    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2021-09-16) GAWANDE, VAISHNAVI VITTHALRAO.; Rathod, Dr. T. H.
    The present investigation entitled “Effect of chitosan on growth and seed cotton yield of cotton (Gossypium hirsutum L.)” was conducted during kharif season, 2020-2021 at Central Demonstration Farm, Wani Rambhapur, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment laid out in randomized block design with four replications and seven treatments comprising of different concentrations of chitosan viz., T1 (control), T2 (25 ppm), T3 (50 ppm), T4 (75 ppm), T5 (100 ppm), T6 (125 ppm) and T7 (150 ppm). Sowing of hirsutum cotton variety AKH-09-5 was done on 28th June 2020 by dibbling method at 60 cm × 30 cm (R × P) spacing. Afterwards, all necessary intercultural operations were executed as and when needed. Foliar sprays of chitosan were carried out twice on 35 and 55 DAS. Morphological parameters were recorded at 30, 60, 90, 120, 150 DAS and days to 50% flowering was recorded at the proper stage. Physiological parameters were recorded at 30, 60, 90, 120, 150 DAS and growth parameters at 30-60, 60-90, 90-120 and 120-150 DAS. Biochemical observation was recorded at 60, 90 and 120 DAS. Yield and yield attributes were recorded at harvest. Parameters on fiber properties were recorded during post-harvest. Results revealed that, significantly maximum values of morphological parameters like plant height (cm), leaf area (dm2), leaf area index; physiological parameters like dry matter production(g), relative water content (%) and growth parameters like crop growth rate (g m-2 day-1), relative growth rate (g g-1 day-1), net assimilation rate (g dm-2 day-1); biochemical parameters like chlorophyll content index (SPAD value); yield and yield attributing parameters like number of sympodial branches, number of bolls, boll weight (g) and seed cotton yield (g) were recorded in treatment T4 (75 ppm chitosan) over control (non treated). Treatment sprayed with 75 ppm chitosan was recorded with the highest per cent increase in yield over control i.e. 28.53 percent. From overall results, it can be concluded that foliar application of chitosan (25, 50, 75, 100, 125 and 150 ppm) induced positive influence on morphological, physiological, biochemical and on yield and yield attributing parameters. However, data recorded represents only one season of cotton crop, so it will require further multilocation confirmation.

    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-11) YADAV, YOGITA MANOHAR.; Rathod, Dr. T. H.
    An experiment was conducted on “Evaluation of American cotton Genotypes for morpho-physiological and Oil parameters”, at the experimental field of Cotton Research Unit, Dr. PDKV Akola, during Kharif season of 2016-17 and 2017-18.The experiment was laid out in randomized block design with three replications and twenty seven treatments. The objectives of the experimental trial were: 1) to study the morpho-physiological and yield attributes of American cotton genotypes. 2) To study the oil parameters of American cotton genotypes. The observations were recorded on various morphological parameters viz., plant height (cm), leaf area (dm2), Total dry matter (g), physiological observations like Leaf area index, relative water content(%), Specific leaf weight (g/dm2), relative growth rate (RGR) (g/g/day), Total chlorophyll content (mg/g) and Absolute growth rate (AGR) (g/day) were recorded at 60, 90, 120 DAS and at harvest. Whereas, yield and oil parameters were also recorded per replication and treatment wise. American cotton (G. hirsutum) AKH-1303 followed by AKH-2013-2 and AKH-2013-1 recorded maximum seed cotton yield. Genotype AKH-1303 recorded more plant height (122.60 cm), leaf area (46.22 dm2), total dry matter (77.21 g), leaf area index (2.07), specific leaf weight (0.88g/dm2) over the other genotypes whereas, AKH-1301 recorded significantly more number of leaves (49.30) ) and more total chlorophyll content (1.39 mg/g) over the other genotypes. The check PKV-Rajat recorded more relative water content. With respect to yield and yield attributes, genotype, AKH-8660 took minimum days to square initiation (43.20 days) and IC-359088 (47.42 days) recorded maximum days to square initiation. AKH-31 (55 days) recorded minimum number of days to 50 % flowering over other genotypes. The minimum number of days to 50 % boll bursting was found in genotype AKH-2012-9 (109.83 days). Genotype AKH-1303 recorded significantly highest number of sympodial branches (15.73), higher number of bolls (16.47), maximum seed cotton yield (62.89 g/plant), lint yield (22.12 g/plant), seed index (10.35 g). The check AKH-8828 (41.31%) recorded best ginning percent and AKH-2012-9 recorded significantly highest boll wt. (3.12 g). Genotype AKH-081 (check) recorded maximum oil content (21.60%), while AKH-8660 showed minimum oil content (12.6%). Genotype AKH-976 recorded maximum erucic (0.84%), and linoleic acid (52.64%). Significantly highest arachidic (0.42%) and stearic acid (3.96%) were observed in genotype check variety PKV-Rajat. Significantly maximum myristic (0.90%) and palmitoleic acid (0.58%) were registered in genotype AK-32.Genotype GV-22 recorded highest palmitic acid (23.96%).Highest oleic acid (22.69%) and linolenic acid (0.31%) were recorded in AKH-8828 and AKH-1302 respectively. Analysis of variance for pooled data indicated that there were significant differences among the twenty seven genotypes. The values of PCV (Phenotypic coefficient of variation) were higher than GCV (Genotypic coefficient of variation) indicating the importance of environment on the expression of these characters. The seed cotton yield, oil and oil quality parameters showed high heritability along with high genetic advance which would be rewarding for improvement in these characters through selection. The seed cotton yield per plant exhibited positive and significant phenotypic and genotypic correlation with plant height, leaf area , total dry matter, number of days to square initiation, number of monopodia, number of sympodia, number of bolls, boll weight and lint yield. The results indicated that these characters are more related genetically.

    Title: SEED BORNE FUNGI OF MUNGBEAN AND ITS MANAGEMENT.
    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-09-28) Authors: DHANDGE, SWAPNIL RAMCHANDRA.; Advisor: Kamble, Miss. Geetanjali A.
    Abstract: Green gram (Vigna radiata (L.) wiczek) is one of the most important pulse crop in India. It is an important wide spreading, herbaceous, annual, legume pulse crop under the family-leguminoseae. It is an excellent source of easily digestible protein and minerals. It is highly nutrious containing 24% of high-quality protein, 1.3% fats, 56.6% carbohydrates and 3% dietary fibers. It is rich in minerals having 140 mg calcium, 8.4% iron and 280 mg phosphorous. It is grown in arid and semi-arid tropics. Several factors are responsible for low production of green gram. Among them, seed borne diseases play an important role. Hence, assessment and management of seed borne fungi of green gram is important. Green gram seed samples of different varieties viz., Vaibhav, TARM-4, TARM-1, TAP-7, AKM-1228, and PKV AKM-4, PKVM-8802, Utkarsh, Kopergaon, Green gold were collected from Pulses Research Unit and CDF, Vani Rambhapur Dr. PDKV, Akola respectively and used for present studies. Seed samples for detection of seed borne fungi were tested by standard blotter paper method (ISTA, 1996). The seed samples of green gram showed association of eight fungi belonging to six genera viz., Alternaria alternata, Aspergillus flavus, A. niger, Curvularia lunata, Fusarium oxysporum, F. semitectum, Rhizoctonia bataticola, Rhizopus spp. However, among all other seed borne fungi F. oxysporum, F. semitectum, R. bataticola and A. alternata were observed as pre dominant fungi in green gram. Fungicides were tested against seed borne fungi in vitro by employing poisoned food method. Combi product Carboxin + Thiram (0.3%) was found most effective fungicides over all other treatments for arresting the mycelial growth (100%) of all associated seed borne fungi followed by Tebuconazole (0.1%). Among bioagents, Trichoderma asperellum was found most effective against seed borne fungi followed by T. herzianum, Bacillus subtilis and Pseudomonas fluorescens.

    (Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-05-30) A, KU. BLESSEENA.; Deotale, Dr. R. D.
    The effect of foliar sprays of tocopherol (100 ppm, 200 ppm, 300ppm, 400 ppm and 500 ppm) and micronutrients (ZnSO¬¬¬4 0.5% and FeSO4 0.5%) on the morphophysiological, chemical, biochemical, yield and yield contributing parameters of chickpea variety JAKI 9218 was studied during rabi 2018-2019 at farm of Botany section, College of Agriculture, Nagpur. Experiment was laid out in RBD design with three replications and eighteen treatments. Sowing was done by dibbling method on 21st October 2018 at a spacing of 30 cm x 10 cm. Thereafter, all the intercultural operations were done as and when required. The recommended dose of 20 kg N ha-1 and 50 kg P2O5 ha-1 was applied in all treatments. Spraying of tocopherol and micronutrients was done two times i.e. on 25 and 40 DAS. Morphophysiological parameters such as plant height, leaf area and dry weight of plant were recorded at 25, 45, 65 and 85 DAS. Whereas, number of branches plant-1 was recorded at the time of harvest. RGR and NAR were calculated at 25-45, 45-65 and 65-85 DAS. Plant height was recorded at maturity. Chemical and biochemical parameters like leaf chlorophyll, N, P, K content in leaves, protein content in seed were also estimated at 25, 45, 65 and 85 DAS. Observations on yield and yield contributing parameters like 100 seed weight, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, plot-1 and ha-1 were recorded. Data obtained from all the observations was statistically analyzed to measure their significance or non-significance. Data revealed that the two foliar sprays of tocopherol (100 ppm) and micronutrient (ZnSO¬¬¬4 0.5%) significantly enhanced morpho-physiological parameters viz., plant height, leaf area, total dry matter production, number of secondary branches plant-1, RGR, NAR, chemical and biochemical parameters viz., nitrogen, phosphorus, potassium, chlorophyll in leaf, protein content in seed, yield and yield contributing parameters viz., 100 seed weight, number of filled pods plant-1, number of unfilled pods plant-1, seed yield plant-1, plot-1 and ha-1 over control. Also, by considering B:C ratio treatment T9 (100 ppm tocopherol + 0.5% ZnSO4) was found more effective treatment exhibiting B:C ratio of 2.61 against 1.97 in control and can be considered as most effective and beneficial treatment in chickpea.

T10 (50 ppm NAA + 300 ppm HA), T11 (50 ppm NAA + 400 ppm HA) and T12 (50 ppm NAA + 500 ppm HA) were tested. Seeds were sown at the rate of 75 kg ha-1 by dibbling method at a spacing of 45 cm x 20 cm on 26th Sept. 2018 after receiving the sufficient rainfall. Thereafter, all intercultural operations were done as and when required. Spraying of humic acid and NAA was done two times at 40 and 70 DAS with hand sprayer. The observations on morpho-physiological, growth analysis, biochemical and chemical parameters like plant height plant-1, number of braches plant-1, total dry weight plant-1, leaf area plant-1, leaf chlorophyll and N, P, K content in leaves were recorded at 40, 60 80 and 100 DAS respectively. Similarly RGR and NAR were calculated at 40-60, 60-80 and 80-100 DAS. Oil content in seeds also estimated. Observations on yield and yield contributing parameters like number of capitula plant-1, number of seeds capitulum-1, 1000 seed weight, seed yield plant-1, plot-1, ha-1 and harvest index were also recorded. Data obtained from all the observations were subjected to statistical analysis. Data revealed that two foliar sprays of 300, 400 and 500 ppm humic acid and 25 and 50 ppm NAA alone or in combination significantly enhanced morpho-physiological parameters viz., plant height, number of branches, leaf area, dry weight of plant, RGR, NAR, chemical and biochemical parameters viz., nitrogen, phosphorus, potassium, chlorophyll in leaf and oil content in seed and yield and yield contributing attributes viz., number of capitula plant-1, number of seeds capitulum-1, 1000 seed weight, seed yield plant-1, plot-1 and ha-1 over control. Considering the treatments under study two foliar sprays of 50 ppm NAA + 300 ppm humic acid at 40 and 70 DAS was found to be most effective treatment in improving morpho-physiological, chemical and biochemical, yield and yield contributing paramaters of safflower cv. PKV-Pink and ultimately increased yield by 56.56 per cent over control.

    The Physiological response of foliar sprays of ascorbic acid (100, 200, 300 and 400 ppm) and zinc sulphate (0.5%) on the morpho-physiological, chemical, biochemical, yield and yield contributing parameters of chickpea cv. PDKV-Kanchan was studied during rabi 2018-2019 at farm of Botany section, College of Agriculture, Nagpur. Experiment was laid out in RBD design with three replications and ten treatments. Sowing was done by dibbling method on dated 22nd Oct 2018 at a spacing of 30 cm x 10 cm. Thereafter, all the intercultural operations were done as and when required. The recommended dose of 20 kg N ha-1 and 50 kg P2O5 ha-1 was applied in all treatments. Spraying of ascorbic acid and zinc sulphate was done two times i.e. on 25 and 40 DAS. Observations about morpho-physiological parameters such as plant height, leaf area and dry weight of plant were recorded at 25, 45, 65 and 85 DAS. RGR and NAR were calculated at 25, 45, 65 and 85 DAS. Plant height was recorded at maturity. Chemical and biochemical parameters like leaf chlorophyll, N, P, K content in leaves, protein content in seed were also estimated. Observations on yield and yield contributing parameters like 100 seed weight, number of pods plant-1, number of seeds pod-1, seed yield plant-1 (g), plot-1 (kg) and ha-1 (q) were recorded. All these above mentioned parameters were analyzed statistically. Foliar sprays of ascorbic acid (100, 200, 300 and 400 ppm) and zinc sulphate (0.5%) significantly enhanced morpho-physiological parameters viz., plant height, number of branches plant-1, leaf area, dry weight of plant, RGR, NAR, chemical and biochemical parameters viz., nitrogen, phosphorus, potassium, chlorophyll in leaf, protein content in seed, yield and yield contributing parameters viz., 100 seed weight, number of pods plant-1, number of seeds pod-1, seed yield plant-1 (g), plot-1 (kg) and ha-1 (q) over control. From overall results, it can be stated that foliar application of ascorbic acid and zinc sulphate with different concentrations improved the morpho-physiological, chemical and biochemical and yield contributing parameters might have helped in attaining better seed yield in the present investigation. The highest per cent increase in yield over control was observed in foliar application of 0.5% zinc + 200 ppm ascorbic acid (T8) i.e. 28.48 % over control (T1). But, considering the B:C ratio foliar application of 0.5% zinc + 200 ppm ascorbic acid was found most effective treatment having B:C ratio of 2.78 as compared to 2.36 in control. Finally on the basis of B:C ratio it is inferred that, spraying plants at 25 and 45 DAS with 0.5% zinc + 200 ppm ascorbic acid could be considered as the most suitable concentration to expect promising improvement regarding the growth parameters, physiological characters and yield quality and quantity of chickpea.
