N.Abstract: The present investigation entitled “Effect of organic sources and PPFM on morphoqualitative traits and soil health in organic cotton under rainfed condition” was carried out at the farm of Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif season of 2016-17 and 2017-18.The experiment was laid out in randomized block design with three replication and ten treatments. The treatments consisted of T1: Absolute control (no organics / Inorganics), T2: RD of nutrient through organics on P equivalent basis (FYM @12.5t ha-1), T3: Seed treatment of biofertilizer (Azatobactor and PSB each @ 25 gkg-1 of seed) + foliar application of PPFM @1 % at FL & BD, T4: Neem cake (NC) @ 250 kgha-1, T5 : GM of sunhemp in between cotton rows (GMS) (1:1), T6: Intercrop with blackgram BGS (1:1), T7: Seed treatment of biofertilizer (Azatobactor and PSB each @ 25 gkg-1 of seed) + PPFM @1 % at FL & BD+ NC, T8: Seed treatment of biofertilizer (Azatobactor and PSB each @ 25 gkg-1 of seed) + PPFM @1 % at FL & BD + cotton+ sunhemp (GMS) (1:1), T9: Seed treatment of biofertilizer (Azatobactor and PSB each @ 25 gkg-1 of seed) + PPFM @ 1 % at FL & BD+ NC + cotton+ sunhemp (GMS) (1:1) and T10 :Seed treatment of biofertilizer (Azatobactor and PSB each @ 25 gkg-1 of seed) + PPFM @1 % at FL & BD+ NC + Intercrop with blackgram BGS (1:1). The experimental soil was Vertisol with clay loam in texture, low in available nitrogen (175.6 kg ha-1), medium in available phosphorus (15.10 kg ha-1) and very high in potassium content (375.4 kg ha-1). The soil pH, EC and organic carbon were 8.08, 0.34 dSm-1 and 3.80 g kg-1, respectively. The crop was sown on 15th June 2016 and 22nd June 2017. Application of recommended dose of nutrient through farm yard manure @12.5 t ha-1 have pronounced significant effect on growth attributes and yield attributes of organic cotton crop and being at par with seed treatment of biofertilzers (Azatobactor and PSB @ 25 g /kg of seed) along with application PPFM @ 1% spray and neem cake application @ 250 kg ha-1 with in- situ mulchning of sunhemp GMS (1:1). The highest seed cotton yield was recorded in the treatment FYM @12.5 t ha-1, however, maximum seed cotton equivalent yield was found in seed treatment of biofertilizer (Azatobactor and PSB @ 25 g /kg of seed) + PPFM @ 1% spray + neem cake @ 250 kg ha-1 with intercropping of blackgram BGS (1:1) and intercrop with cotton + blackgram BGS (1:1) only. Organic sources of manures had no significant impact on ginning percentage, seed index, lint index, oil content and all the fiber quality parameters, but numerically higher values were observed in FYM @ 12.5 t ha-1 followed by seed treatment of biofertilizer (Azatobactor and PSB @ 25 g /kg of seed) + PPFM @ 1% spray at flowering and boll development stage + neem cake @ 250 kg ha-1 with cotton + blackgram. The treatment of recommended dose of nutrient supplied through FYM differ significantly in relation to growth, yield and uptake of nutrients as compared to plant based organic sources of manures. The NPK uptake, physico-chemical and biological properties were improved through different organic sources. The organic carbon values were improved with treatment of FYM @ 12.5 t ha-1, seed treatment of biofertilizer (Azatobactor and PSB @ 25 g /kg of seed) + PPFM @ 1% spray + neem cake @ 250 kg ha-1 + in-situ green maurring sunhemp at 40DAS and cotton + intercropping over initial values of organic carbon as well as over control. Seed treatment of biofertilizer (Azatobactor and PSB @ 25 g/kg of seed) + PPFM+ neem cake @ 250 kg ha-1 with intercropping of blackgram with cotton was found better in terms of GMR, NMR and B: C ratio as well as economic efficiency. On the basis the above findings, it is concluded that the use of different organic sources i.e biofertilizers, neem cake, PPFM and green manures, intercropping with blackgram among that treatment of FYM found better for maximizing yield and improving soil health. However, based on low cost technology seed treatment of biofertilizers (Azatobactor and PSB @ 25 g /kg of seed) followed by PPFM PGR spray @ 1% + neem cake 250 kgha-1 with cotton + blackgram intercropping system (1:1) was emerged as the best alternative to FYM for economic efficiency and monetary returns of organic cotton along with enhancing soil health by growing improved Hirstum variety of cotton under rainfed conditions.ThesisItem Open Access Title: SITE SPECIFIC NUTRIENT MANAGEMENT BASED ON STCR IN SAFFLOWER (Carthamus tinctorius L.).(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2020-12-30) Authors: HIWALE, SUMEDH DEVIDAS.; Advisor: Chorey, Dr. A. B.Abstract: A field experiment entitled “Site specific nutrient management based on STCR in safflower (Carthamus tinctorius l.)” was conducted during the rabi season of 2017-18 and 2018-19 at Research Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Experimental plot was clayey in texture with medium in organic carbon (0.59%), low in nitrogen (194 kg ha-1), medium in phosphorus (26.10kg ha-1),fairly high amount of potash (325 kg ha-1) and slightly alkaline in nature. The soil was medium deep black belonging to Vertisols. The experiment was laid out in factorial randomized block design replicated four times. The factor ‘A’ consisted of three manure application treatments i.e. M0- no manure, M1 - 5 t FYM ha-1 and M2 - greengram residue incorporation. while the factor ‘B’ consisted of five nutrient management treatments viz., F0- control (no fertilizer), F1 - recommended NPK, F2 - SSNM (STCR equation), F3 - SSNM (STCR equation) + (ZnSO4 @ 25 kg ha-1+ S @ 10 kg ha-1)and F4 - SSNM (NPK) (deficient + 25 % rec.; Medium: rec.; high: -25 % rec.) with fifteen treatment combination. Objective of study was to evaluate the manure application, nutrient management treatments and their interaction effect on growth, yield, quality, nutrient uptake and economics of rabi safflower.Crop variety used in the present investigation was AKS-207. This variety has been evolved by AICRP safflower Centre, Dr. P.D.K.V. Akola. This variety has suitable for Vidarbha region of Maharashtra. Experimental results revealed that, out of various manure application the application of 5 t FYM ha-1 significantly improved the all growth contributing characters, root parameters, yield attributing parameters, seed yield (kg ha-1), biological yield (kg ha-1), and straw yield (kg ha-1) as compared to no application of manure and found comparable with greengram residue incorporation treatment. The treatment of manure application with 5 t FYM ha-1 significantly improved the days to 50% flowering, days to rosette stage of safflower and chlorophyll content in leaves over no manure application treatment and greengram residue incorporation treatment. Significantly higher oil content (%), oil yield (kg ha-1) and protein content (%), protein yield (kg ha-1) were recorded with application of 5 t FYM ha-1 than the other manure application treatments. No significant influencewas noticed with respect to aphid population and test weight (g) by manure application treatments. Total uptake of nitrogen (kg ha-1), phosphorus (kg ha-1), potassium (kg ha-1), sulphur (kg ha-1), zinc(g ha-1) and available nitrogen (kg ha-1), phosphorus (kg ha-1), potassium (kg ha-1) and sulphur (mg kg-1) found significantly higher under application of 5 t FYM ha-1 than other manure application treatments.Available zinc in soil at harvest was found to be non-significant due to manure application treatments during both the years of i.e. 2017-18 and 2018-19. Soil bacterial, fungal and actinomycetes population at harvest of safflower was found significantly higher under the treatment with application of 5 t FYM ha-1andsuperior over remaining other manure application treatments during both the years study. Higher values for gross monetary returns, net monetary returns and economic efficiency were recorded under application of 5 t FYM ha-1 than no manure and greengram residue incorporation during both the years. However, benefit cost ratio of safflower was found significantly greater with application of greengram residue incorporation, and found superior over no manure and 5 t FYM ha-1 treatments. No manure treatment was recorded lowest growth, yield attributes, root characters, seed yield, biological yield, straw yield, protein yield, oil yield and total uptake of N, P, K, S, as well as economics of safflower. Among the various nutrient management practices treatment of SSNM (STCR equation) along with ZnSO4 @ 25 kg ha-1 + S @10 kg ha-1 recorded significantly higher growth characters viz. plant height, number of branches plant-1, leaf area plant-1, dry matter accumulation plant-1, root dry weight than rest of the treatments and found statistically at par with treatment of SSNM (STCR equation) during both years of investigation. Similarly, yield attributes of safflower were also recorded significantly higher with the application of F3 - SSNM (STCR equation) + (ZnSo4 @ 25 kg ha-1+ S @ 10 kg ha-1)and remain at par with fertilizer application through F2 - SSNM (STCR equation). Application of fertilizer through SSNM (STCR equation) along with ZnSO4 @ 25 kg ha-1+ S @ 10 kg ha-1 recorded higher seed, protein, oil yield, GMR, NMR, economic efficiency and B:C ratio ha-1. The NPK uptake by the crop was higher with fertilizer application through F3 - SSNM (STCR equation) + (ZnSO4@ 25 kg ha-1+ S @ 10 kg ha-1)and found statistically comparable with the treatment of SSNM (STCR equation). The available NPK in soil after harvest were also found highest with the application of fertilizer with SSNM (STCR equation) + (ZnSO4 @ 25 kg ha-1+ S @ 10 kg ha-1) during both years of investigation. From the two years study, it is concluded that, the nutrient management treatments did not showed significant influence on aphid population and soil moisture content (%) at different growth stages of safflower. Days to 50% flowering, days to rosette stage and chlorophyll content in plant increased significantly with SSNM (STCR equation) + (ZnSO4@ 25 kg ha-1+ S @ 10 kg ha-1)as compared to other nutrient management treatments and found numerically on par with treatment of SSNM (STCR equation). Among nutrient management treatments, the treatment of SSNM (STCR equation) + (ZnSO4 @ 25 kg ha-1+ S @ 10 kg ha-1)registered higher microbial population of bacteria, fungi and actinomycetes and found statistically at par with SSNM(STCR equation) treatment during both the years. As regards growth characters, yield attributes quality parameter, seed yield, biologicalyield, straw yield, economics and total uptake of N,P,K, S,Zn and availableN,P,K, S as well as microbial population were found lowest under the treatment of no fertilizer during the years of study.ThesisItem Open Access Title PERFORMANCE OF Bt COTTON UNDER ETc BASED DRIP IRRIGATION AND POLYMULCH TECHNIQUE.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2020-09-27) Authors: ISAL, RAJABHAU LAXMAN; Advisor: Wanjari, Dr. S. SAbstract: A field experiment entitled "PERFORMANCE OF Bt COTTON UNDER ETc BASED DRIP IRRIGATION AND POLYMULCH TECHNIQUE."was conducted at the Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra (India) during kharif 2013-14 and 2014-15 on clayey soil. The cotton crop was sown on 12th June during both the years. The experiment was sown on broad bed furrow laid out with eight treatment combinations in Factorial Randomized Block Design replicated thrice. Treatment comprises of without polythene mulch and with polythene mulch and four irrigation levels as 0.4 ETc, 0.6 ETc,0.8 ETc and 1.0 ETc were constituted the factor I and the factor II respectively and check treatment was taken as farmers practice, where sowing was done on ridges and furrow with polythene mulch and without polythene mulch. 12The soil of experimental plot was medium deep black with fairly uniform and levelled topography. The rainfall at initial stages of crop growth was more than normal during first year and less than the normal during second year of experimentation. During 2013-14, the weather parameter were about normal, whereas during 2014-15, weather parameters fluctuations were sometimes extreme and not so satisfactory for crop growth . Plant height along with growth parameter viz., number of leaves, number of sympodial branches, leaf area and total dry matter plant-1 were significantly improved under polythene mulch during 2013-14 and 2014-15. Application of polythene mulch recorded significantly higher number of bolls plant-1 and seed cotton yield plant-1 seed cotton yield ha-1, stalk and biological yields ha-1 over without polythene mulch during both the years of experimentation. The soil moisture content, water use efficiency and soil temperature were higher under polythene mulch than without polythene mulch. Uptake of nitrogen, phosphorus and potassium were also higher under polythene mulch. The gross and net monetary returns and B:C ratio were marginal under polythene mulch. Among the four irrigation levels, irrigation level of 1.0 ETc showed higher values of growth parameters such as functional leaves, sympodial branches, leaf area plant-1 and total dry matter plant-1. Whereas, it was comparable with irrigation at 0.8 ETc. As regards yield attributes, number of bolls plant-1, boll weight and seed cotton yield plant-1 were significantly higher with irrigation level 0.8 ETc over 0.4 ETc and 0.6 ETc but was found on par with irrigation level 1.0 ETc. Irrigation level of 0.8 ETc recorded higher seed cotton yield, stalk yield and harvest index. The soil moisture content was significantly higher under the irrigation level at 1.0 ETc, however, water use efficiency was higher under irrigation level 0.4 ETc followed by 0.6 ETc and 0.8 ETc. The higher uptake of nitrogen, phosphorus and potassium, gross monetary returns, net monetary returns and B:C ratio were recorded with the irrigation level 0.8 ETc fallowed by 1.0 ETc,0.6 ETc and 0.4 ETc irrigation levels. Polythene mulch produced higher growth contributing,yield and yield attributes over without polythene mulch due to higher growth of plant under the polythene mulch. Irrigation level of 1.0 ETc gave the highest values as regards to growth and growth contributing characters, however yield and yield attributes were higher in irrigation level 0.8 ETc As regards to check treatments (farmers practice) sowing on ridges and furrow with polythene mulch gave higher values of growth parameters viz., number of leaves, number of sympodial branches, leaf area plant-1, total dry matter plant-1, yield attributes, gross monetary returns, net monetary returns, and B:C ratio over sowing on ridges and furrow without polymulch during 2013-14 and 2014-15. On the basis of two years data, it could be concluded that application of polythene mulch (silver-black) with 0.8 ETc irrigation throug drip found better for increasing the productivity and economic returns of cotton while saving the water.ThesisItem Open Access STUDIES OF AGROMETEOROLOGICAL INDICES OF COTTON ((Gossypium hirsutum L.)) GENOTYPES UNDER DIFFERENT SOWING TIMES AND PLANT DENSITY.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-04-06) DHAKATE, ANANT AMBADAS.; Tupe, Dr. A. R.Abstract: A research entitled “Studies of Agrometeorological indices of cotton genotypes under different sowing times and plant density” was conducted at the All India Coordinated Research Project on Agrometeorology, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) during kharif season 2019-20. Three cotton genotypes viz, hirsutum cotton AKH-081, arboreum cotton AKA-7 and Bt cotton Balwan with two plant densities at the population density of 60 x 10 cm (1,66,666 pl/ha) and 75 x 10 cm (1,33,333 pl/ha) with two weather variability of monsoon sowing and late sowing were laid out in split plot design with three replications. Soil of experimental plot was medium deep black. Cotton crop was sown on June 28 and July 12, 2019. Total rainfall of 775.0 mm received during the crop growing season. Monsoon sowing recorded more physiological growth in terms of plant height, number of leaves, dry matter accumulation than late sowing and gives more seed cotton yield than late sowing. Bt cotton genotype Balwan recorded higher growth in terms of leaf area and total dry matter weight plant-1. Significantly more number of sympodial branches, number of boll and seed cotton weight plant-1 was produced by Balwan. Genotype Balwan required more number of days to maturity. High population density at 60 x 10 cm (1,66,666 pl/ha) lowered growth and yield attributes plant-1 and caused earlier maturity of crop. Genotype Balwan recorded higher seed cotton yield (1731 Kg ha-1) than AKH 081 (1517 Kg ha-1) and AKA-7 (1414 Kg ha-1). High population density at 60 x 10 cm (1,66,666 pl/ha) though has smaller individual boll size (weight) and fewer bolls plant-1, however, the increased number of plants compensated for fewer yield attributes plant-1 and cumulatively seed cotton yield output was significantly higher (1629 Kg ha-1). Population density of 75 x 10 cm (1,33,333 pl/ha) yielded 1479 Kg ha-1¬ seed cotton. Ginning percentage was more with AKA-7 (40.93%) followed by AKH 081 (38.48%) and Bt cotton genotype Balwan (37.00%). Bt cotton genotype Balwan recorded higher 2.5% span length (26.60) followed by AKH 081 (26.00) and AKA-7 (24.02). Lint index was more with AKH 081 (4.87) followed by AKA-7 (4.08) and Balwan (3.87). Over the cotton canopy, canopy temperature was lowest in AKH 081. Therefore, hirsutum cotton genotype AKH 081 have an advantage with respect to not only light capture in the canopy but also due to the ability to maintain more favorable (cooler) canopy temperatures indicative of comparatively lower degree of field scale plant water stress in AKH 081 and its greater tolerance to environmental stress comparative to genotype Balwan and AKA-07. Relative humidity during morning hours was higher by about 20 % during earlier growing stage and by about 30 % during later stages of crop growth. Radiation intensity was comparatively more in monsoon sowing than late sowing, radiation intensity was comparatively more with increased population density from 1,33,333 pl ha-1 to 1,66,666 pl ha-1. Earliest sown crop recorded the highest (2107.7 D0) thermal units. Thermal use efficiency and Radiation use efficiency of crop was highest in monsoon sowing.ThesisItem Open Access RESPONSE OF FODDER OAT TO SILICON LEVELS UNDER DIFFERENT CUTTING MANAGEMENT(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-01-06) WANJARI, RAGINI MUKESHRAO.; Chorey, Dr. A. B.Abstract: A field experiment entitled “Response of fodder oat to silicon levels under different cutting management’’ was conducted during rabi season of 2018 at the farm of Agronomy department, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola.

However, crude fibre (36.82%) and nitrogen free extract (55.26%) was higher in silicon application @150 kgha-1. No cut treatment recorded highest plant height and dry matter accumulation at harvest (26.74 g), seed yield (18.14 q ha 1) and straw yield (140.58 q ha 1), crude protein yield (5.43 qha 1) and crude fibre yield (46.72 qha 1) after harvest, total N,P,K and Si uptake (116.38, 28.47,124.45 and 2.62 kgha-1), available N,P,K and Si in soil after harvest (237.59, 20.63, 348.92 and 68.39 kgha 1) while cut at 55 DAS produced significantly higher number of tillers at harvest, green forage yield (290.18 q ha 1) and dry matter yield (40.15 q ha 1), crude fibre (36.80 %), ether extract (3.07 %), ash content (8.19 %), crude protein yield (2.99 qha 1) and crude fibre yield (14.48 qha 1) at cut, Gross Monetary Returns (Rs. 98714 ha¬-1), Net Monetary Returns (Rs. 65007 ha-1) and B:C ratio (2.92). However, cut 45 DAS recorded highest crude protein (7.18 %) and NFE (55.38%).ThesisItem Open Access EFFICACY OF PRE AND POST EMERGENCE HERBICIDES AGAINST WEED FLORA IN ONION (Allium cepa L.).(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2020-09-30) THAKARE, AKANKSHA MANOJ.; Kakade, Dr. S. U.Abstract: The field experiment was conducted at AICRP-Weed Management, Agronomy farm, Dr. Panjabrao Deshmukh Krishi Vidyapith, Akola to study the “Efficacy of pre and post emergence herbicides against weed flora in onion (Allium cepa L.)” during the year of 2018-19 in rabi season. The experiment was carried out to study the relative efficacy of herbicides and cultural practice on weed control in onion as well as to study its effect on growth and yield of onion. The experiment was laidout in randomized block design with nine treatment replicated thrice. In the present experimentation, chemical weed management practices i.e. herbicides used under treatment were Pendimethalin 24% + Oxyfluorfen 4% ZE @480+82 g a.i./ha (T1), Pendimethalin 24% + Oxyfluorfen 4% ZE @541.80+92.56 g a.i./ha (T2), Pendimethalin 24% + Oxyfluorfen 4% ZE @600+102.5 g a.i./ha (T3), Pendimethalin 24% + Oxyfluorfen 4% ZE @1083.60+185.12 g a.i./ha (T4) are the herbicide with combine (pre-mix) formulation with different concentration of active ingredient and other treatments were Pendimethalin 38.7% CS @ 677.25 g a.i./ha (T5), Oxyfluorfen 23.5% EC@ 200 g a.i./ha (T6), Quizalofop ethyl 5% EC@ 50 g a.i./ha (T7), 2 HW 25 & 45 DAT (T8) and weedy check (T9). All the recommended agronomic practices were followed for raising the crop. The soil of experimental field characterized as clayey in texture, having slightly alkaline pH (7.7), moderate organic carbon status (0.41%), low nitrogen content (197.21 kg ha-1), medium available phosphorus content (18.76 kg ha-1), high potassium status (366.49 kg ha-1). Onion (Variety-Akola safed) was transplanted on 14th December 2018 at 20 x 10 cm spacing with 100:50:50 kg ha-1 NPK. The crop was harvested on 9th April 2019. Weed species recorded in experimental field were Stromatium dhatura, Parthenium hysterophorus, Euphorbia hirta L., Commelina benghalensis, Alternanathera triandra., Digera arvensis Forst., Tridax procumbens L., Euphorbia geniculata Orteg., Argemone mexicana L., Xanthium strumarium L., Chenopodium album L., Phyllanthus niruri L., Portulaca oleracea L., Lagasca mollis, Acalypha indica among the dicot weeds and among monocot the dominant weeds were Cyprus rotundus, Cynodon dactylon, Eleusin indica L. and Dactyloctenium aegyptium L. Weedy condition throughout the crop growth period caused 40 to 80 % reduction in bulb yield of onion. Among the herbicidal treatments, Pendimethalin 24% + Oxyfluorfen 4% ZE @600+102.5 g a.i./ha was found to be effective in controlling weeds across the crop growth period. Among the various treatments under study weed free recorded significantly higher values of major parameters whereas, in herbicidal treatments, the maximum growth and yield attributes were recorded with treatment Pendimethalin 24% + Oxyfluorfen 4% ZE @600+102.5 g a.i./ha which were at par with Pendimethalin 24% + Oxyfluorfen 4% ZE @1083.60+185.12 g a.i./ha. The same treatment recorded better weed control efficiency and lowest weed index. The lowest weed density of both monocot as well as dicot was observed in treatment with spraying of pendimethalin 24% + oxyfluorfen 4% ZE @600+102.5 g a.i./ha as pre emergence which ultimately result in lowest weed dry matter accumulation , higher weed control efficiency and lower weed index. The nutrients uptake by weeds was more in weedy condition. However, total nutrient uptake by crop was observed maximum with application of Quizalofop ethyl 5% EC@ 50 g a.i./ha. Treatment with application of pendimethalin 24% + oxyfluorfen 4% ZE @600+102.5 g a.i./ha PE was recorded with highest onion bulb yield production and hence these treatment was found most economical with maximum value of GMR (188290 Rs ha-1) and B: C ratio (3.04).ThesisItem Open Access RESPONSE OF CHICKPEA (Cicer arietinum L.)

Chickpea variety JAKI-9218 was sown on 13th November 2018 at 30 cm x 10 cm spacing with 25:50:30 kg N: P2O5: K2O ha-1. The crop was harvested on 5th March 2019. Single application of 45ppm GA3 at flower initiation recorded significantly higher plant height at 68 DAS. Single application of 45ppm GA3 at flower initiation recorded significantly more number of leaves plant-1 at 49 DAS and recorded significantly higher leaf area plant-1 (22.10 cm2) and significantly higher values of ‘total chlorophyll’ At 49 DAS. At 49 and 68 DAS and at harvest, two applications of 30 ppm GA3 at flower and pod initiation stages recorded significantly higher dry matter accumulation in chickpea crop. Out of eleven treatments tested under experiment, the yield attributing parameters like number pods plant-1, grain yield plant-1 and seed index were found significantly highest in foliar treatment application of 30 ppm GA3 at flower and pod initiation stages. This treatment also recorded significantly highest grain yield kg ha-1 among all the treatments. The effect of various treatments on grain protein content was found non- significant. Highest gross monetary returns and net monetary returns were found in the treatment of two applications of 30ppm GA3 at flower and pod initiation stages. However, two applications of 15ppm GA3 at flower and pod initiation stages recorded higher value of benefit: cost ratio. The effect of various treatments on nutrient uptake by the chickpea crop was found non- significant.ThesisItem Open Access EFFECT OF ORGANIC SOURCES OF NUTRIENTS ON COTTON BASED INTERCROPPING SYSTEMS.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2020-10-21) POTE, VISHAL SHRIKRUSHNARAO.; Ganvir, Dr. M. M.Abstract: Field investigation entitled “Effect of organic sources of nutrients on cotton based intercropping system” was carried out during kharif season 2019-20 at research farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). The experiment was laid out in Strip Plot Design (SrPD) with four mainplot factors i.e. intercropping system (T1 – Cotton + Blackgram 2:1, T2 - Cotton + Sunhemp 2:1, T3 - Cotton + Pigeonpea 6:1 and T4 – sole Cotton and three sub plot factors i.e. organic integrated nutrient management (N1 – 100% FYM + Vermicompost, N2 – 75% FYM + Vermicompost + 25% Neem cake and N3 – Control) replicated three times. The varieties adopted are AKA-7 (Cotton), Blackgold (Blackgram). PKV-Tara (Pigeonpea) and Local (Sunhemp). Plant height (cm) was higher in cotton + sunhemp (2:1) intercropping system. Leaf area, number of sympodial branches, dry matter accumulation, root length and root dry weight was highest at 120 DAS in cotton + sunhemp (2:1). Higher chlorophyll content was recorded in cotton + sunhemp (2:1) intercropping system. Total leaf biomass added (kg ha-1) and total biomass added for in-situ decomposition (kg ha-1) was higher in Cotton + Pigeonpea (6:1) intercropping system than other intercropping system. Number of picked boll plant-1 and seed cotton yield plant-1 was higher in cotton + sunhemp (2:1) intercropping system due to the better growth of cotton crop. Seed cotton yield (kg ha-1), stalk yield (kg ha-1) and lint yield (kg ha-1) was higher in sole cotton rather than other intercropping system. Higher seed cotton equivalent yield (kg ha-1), system productivity and total uptake of N and K (kg ha-1), GMR, NMR, B:C ratio and system profitability was recorded in cotton + pigeonpea (6:1) intercropping system. Among the organic integrated nutrient management treatments, application of 75% FYM + Vermicompost + 25% Neem cake influenced plant height (cm) at 60DAS, leaf area (dm2) at 60 DAS, sympodial branches at 60 DAS, dry matter accumulation plant-1 (g) at 60 DAS, SPAD reading at 60 DAS, seed cotton yield (kg ha-1), stalk yield (kg ha-1) and NPK uptake. Soil fertilitystatus was higher in 75% FYM + Vermicompost + 25% Neem cake treatment. Treatment with 75% FYM + Vermicompost + 25% Neem cake recorded higher seed cotton equivalent yield (kg ha-1), Gross monetary and comparable net monetary returns (Rs. ha-1).ThesisItem Open Access EFFECT OF ORGANIC PLANT GROWTH PROMOTER (OPGP) ON SOYBEAN CROP.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-03-25) PATIL, PRASHANT VASANTA.; Khadse, Dr. V. A.Abstract: The present investigation entitled “Effect of organic plant growth promoter (OPGP) on soybean crop”. The field experiment was conducted at Centre for Organic Agril. Research and Training, Agronomy Farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashatra during kharif season 2019. The experiment was laid out in randomized block design with seven treatments combination and three replications. Treatment consist of six foliar spray of organic plant growth promoter (OPGP) @ 2.5 per cent concentration viz., Panchagavya, Jeevamrut, Cow urine, Vermiwash, Goat urine, Decomposer. These sprays were applied at 20, 40 and 60 days intervals after sowing of crop. The soil of experimental plot was clay in texture. Soil was slightly alkaline in reaction, the soil was moderate in available nitrogen, low in available phosphorus high in available potassium, and moderate in organic carbon. The soybean variety Suvarna Soya (AMS-MB-5-18) was sown on 30th June 2019 and harvested at 17th October 2019. The experiment was laid out in randomized block design with seven treatments and three replications. The gross plot size was 6.00 m x 5.40 m. Organic plant growth promoters (OPGP) were analyzed on chemical and biological basis before application. Panchagavya has recorded higher macro and micro nutrients along with beneficial microbial count viz., bacteria, fungus and actinomycetes as compared to other liquid organic plant growth promoter. Experimental result revealed that growth characters i.e. plant height, number of leaves, leaf area, number of branches, number and dry matter accumulation of soybean were significantly higher with the application of foliar spray of Panchagavya @ 2.5 per cent over all other organic plant growth promoters spray except foliar spray of Vermiwash @ 2.5 per cent which showed at par performance. Yield attributes viz., number of pods plant-1 (41.09), seed weight plant-1 (12.47 g) and seed yield (1846 kg ha-1), straw yield (2128 kg ha-1) and biological yield (3974 kg ha-1) of soybean were recorded maximum with application of foliar spray of Panchagavya @ 2.5 per cent, which was found at par with foliar spray of Vermiwash @ 2.5 per cent over rest of the treatments. Highest gross monetary returns, net monetary returns and B:C ratio on the basis of growth, yield and economics studies were recorded with treatment foliar spray of Panchagavya @ 2.5 per cent.
