ThesisItem Open Access Title: IMPACT OF ORGANIC NUTRIENT MODULES ON PRODUCTIVITY OF PIGEONPEA BASED INTERCROPPING SYSTEM.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-15) Authors: SANJAY, D. J.; Advisor: Ganvir, Dr. M. M.Abstract: The field experiment entitled “Impact of organic nutrient modules on productivity of pigeonpea based intercropping system’’ was conducted during Kharif season of 2018-19 at research farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to find out effect of different organic integrated nutrient management on pigeonpea based intercropping systems. The experiment was laid out in Strip Plot Design (SrPD) with four main plot factors i.e. intercropping system (T1 – Sole Pigeonpea, T2 - Pigeonpea + Soybean 1:4, T3 - Pigeonpea + Foxtail millet 1:4 and T4 - Pigeonpea + Cotton 1:4) 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 PKV-Tara (pigeonpea), AMT-1001 (soybean), Co 1 (foxtail millet) and AKA-7 (cotton). Plant height (cm) was higher in pigeonpea + cotton (1:4) intercropping system. Number of leaves plant-1 was not influenced by the intercropping system. Leaf area, leaf area index and number of branches was maximum at 120 DAS in pigeonpea + foxtail millet (1:4) intercropping system. Number of root nodules and root volume of the pigeonpea crop, dry matter accumulation plant-1 (g) and root dry matter accumulation plant-1 (g) was more in sole pigeonpea. Total leaf biomass added (kg ha-1) and total biomass added for in-situ decomposition (kg ha-1) was higher in pigeonpea + soybean (1:4) intercropping system than other intercropping system. Number of pod plant-1, number of seed plant-1, seed yield (kg ha-1), stalk yield (kg ha-1) and total uptake of NPK (kg ha-1) was found higher in pigeonpea + soybean (1:4) intercropping system. Among organic integrated nutrient management treatment 75% FYM + Vermicompost + 25% Neem cake significantly influenced dry matter accumulation in plant (g) at 90 and 120 DAS, root dry matter (g) at 90 DAS, number of pod plant-1, number of seed plant-1, grain yield (kg ha-1), stalk yield (kg ha-1) and NPK uptake. Pigeonpea + Soybean (1:4) intercropping with organic integrated nutrient management of 75% FYM + Vermicompost + 25% Neem cake was found significantly higher seed yield (kg ha-1), pigeonpea equivalent yield (kg ha-1), system productivity (kg-1 ha-1 day-1), net monetary returns, B:C ratio and system profitability (Rs.-1 ha-1 day-1). Quality parameters viz. protein content (%), protein yield (kg ha-1), oil content (%), oil yield (kg ha-1) were also found higher values in pigeonpea + soybean (1:4) intercropping system. In brief, OINM combination of 75% FYM + Vermicompost + 25% Neem cake in pigeonpea + soybean (1:4) intercropping treatment recorded higher PEY and economic returns.ThesisItem Open Access Title: IMPACT OF ORGANIC NUTRIENT MODULES ON PRODUCTIVITY OF PIGEONPEA BASED INTERCROPPING SYSTEM.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-15) Authors: SANJAY, D.

An experiment on, “Effect of different decomposing culture on quality of compost from weed biomass” was carried out during August to November in year 2018-19 at Centre for Organic Agriculture Research and Training (COART) Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola with twelve treatments as different weed biomass viz., of Cassia tora, Sorghum helepense, Parthenium hysterophorus and some other species of weed replicated thrice in Factorial Randomized Block Design by using different decomposing cultures like S-9 culture, PDKV culture and Dung slurry. The periodical chemical analysis carried during weed composting indicated decrease in pH, total organic carbon, C:N ratio while increase in nutrient content and microbial population with the advancement of composting. Composting samples were collected and analyzed for chemical and biological properties at different stages viz., 30, 60, 90 DAF tanks and at maturity (differed with different treatments). Initially the maximum temperature (47.2 0C) was recorded in Parthenium hysterophorus followed by 45.6 in mix weed, 45.1 0C in Sorghum helepense and 44.8 0C in Cassia tora compost at 3 weeks after filling of compost pits. Further the temperature was steadily decreased towards maturity. Among the three decomposing culture PDKV culture recorded highest temperature followed by S-9 and dung slurry. It was revealed that Sorghum helepense weed biomass indicated statistically higher reduction of about 32.69 kg over initial weight added in compost pit of 60 kg at start of filling of compost pit. However, Cassia tora recorded less reduction in weight of about 29.13 kg. Mix weed recorded reduction in weight of about 31.80 kg and Parthenium hysterophorus recorded reduction in weight of about 31 kg over initial weight of material added in compost pit of 60 kg. Among four weed biomass, the pH was significantly highest in mix weed during composting (7.38 at 30 DAF and 7.92 at DAF respectively). At maturity, EC of mix weed compost was significantly lower than other weed compost. At maturity stage mix weed compost showed significantly maximum reduction (20.58 %) in total organic carbon while the lowest C:N ratio (15.13: 1) was recorded with mix weed compost. Mix weed compost was rich in total N (1.36 %), P (0.65 %) and K (0.59 %) followed by Cassia tora, Parthenium hysterophorus and Sorghum helepense compost. Among the different weed biomass, compost obtained from mix weeds recorded significantly maximum bacterial, fungal and actinomycetes population at maturity.ThesisItem Open Access Title: EFFECT OF LIQUID INOCULANTS OF AZOSPIRILLUM BRASILENSE AND PHOSPHATE SOLUBILIZING BACTERIA ON GROWTH AND YIELD OF SORGHUM.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-06-24) Authors: PANDA, DEBESH KUMAR; Advisor: Nemade, Dr. S. M.Abstract: A field experiment entitled “Effect of liquid inoculants of Azospirillum brasilense and phosphate solubilizing bacteria on growth and yield of sorghum” was undertaken during the kharif season of 2018 on clay loam soil of Sorghum Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). An experiment was laid out in the factorial randomized block design in three replications. There were twelve treatment combinations consisting of three different levels of RDF viz., F1 - 50% RDF, F2 -75% RDF, F3 -100% RDF (80:40:40 kg/ha of N:P2O5:K2O) and four seed treatments viz., S1 -Control (without seed treatment and only application of fertilizer), S2 - seed treatment with Azospirillum brasilense and phosphate solubilizing bacteria @ 25 g each/kg seed, S3 - seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 2 ml each/kg seed and S4 - seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 4 ml each/kg seed. Among different levels of RDF, 100% RDF recorded significantly higher plant height (203.68 cm), total dry matter (g/plant) accumulation (145.50 g), grain yield (43.06 q/ha), fodder yield (92.75 q/ha), protein content (9.61%), protein yield (414.26 kg/ha), NPK uptake, available nutrient status (kg/ha), GMR (Rs 101024/ha), NMR (Rs 75818/ha) and B:C ratio (3.01). However, application of 50% RDF recorded significantly higher rhizospheric effect (cfu/g of soil) of both Azospirillum and PSB at seedling, flowering and grain filling stages. Seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 4 ml each/kg seed recorded significantly higher plant height (198.93 cm), total dry matter (g/plant) accumulation (140.79 g), grain yield (43.27 q/ha), fodder yield (93.78 q/ha), protein content (9.60%), protein yield (415.53 kg/ha), NPK uptake, available nutrient status (kg/ha), rhizospheric effect (cfu/g of soil) of both Azospirillum and PSB at seedling, flowering and grain filling stages. GMR (Rs 101687/ha), NMR (Rs 76981/ha) and B:C ratio (3.11) over other seed treatments. However, S4 - seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 4 ml each/kg seed was statistically at par with S3 - seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 2 ml each/kg seed in growth, yield, nutrient uptake and economics of sorghum. Thus, application of 100% RDF and seed treatment with liquid Azospirillum brasilense and phosphate solubilizing bacteria @ 2 ml each/kg seed found promising over other respective treatments.ThesisItem Open Access Title: EFFECT OF TILLAGE AND WEED MANAGEMENT PRACTICES IN SOYBEAN UNDER INCEPTISOL.(Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-12) Authors: MANTE, ASHWINI RAMDAS.; Advisor: DESHMUKH, Dr. J.
