B.; Amarshettiwar, Dr. S. B.The present investigation on “Morpho-physiological and biochemical response of rabi sorghum genotypes to moisture stress under late sown rainfed condition” was carried out during rabi 2015-16 and 2016-17, at Sorghum Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. To estimate the morpho-physiological, growth and biochemical parameters associated with moisture stress tolerant under late sown rainfed condition and finding association among these all parameters for stress tolerant through correlation with yield for further study. The experiment was laid out in randomized block design, replicated thrice with thirteen genotypes (treatments) viz., M 35-1 (c), Phule Anuradha (c), Ringni (c), CSV-22R, CSV-26R, CSV-29R, Parbhani Moti, PKV-Kranti, Phule Maulee, Elongvan-19, Elongvan-42, Elongvan-227, Elongvan-277. Sowing was done under late condition by dibbling method on 21st November 2015 and 2016. Gap filling was done and plant protection measures were applied when necessary. Periodic observations were recorded on morpho-physiological parameters viz., leaf area plant-1, total dry matter, RWC, CTD, CCI and stomatal frequency at 30, 60 and 90 DAS with plant height at 30, 60, 90 DAS and harvest. Different growth parameters viz., RGR, CGR and AGR at 30-60 and 60-90 DAS while, LAI, SLW and number of green leaves plant-1 at 30, 60 and 90 DAS whereas, biochemical parameters like leaf proline content, CSI and nitrogen content in leaves were recorded at 60 and 90 DAS, nitrogen, protein and micronutrients content in seed were estimated after harvest and periodic soil moisture content was noted in thirty days interval upto harvesting. Observations on yield and yield contributing parameters were also recorded per replication and genotype (treatment) wise at harvest. Morpho-physiological, growth and biochemical parameters were correlated with grain yield. In the present investigation results revealed that genotype CSV-29R recorded significantly maximum leaf area plant-1 (21.85 dm-2), TDM plant-1 (108.75 g), RWC (65.85%), CTD (1.35oC) and CCI (39.20) at 90 DAS and abaxial (156.50 mm-2), adaxial stomatal frequency (132.0 mm-2) at 50 % flowering stage. Whereas, plant height-1 an maximum under CSV-26R (212.29 cm) at harvest, Among the genotypes, CSV-29R exhibited more RGR (0.34 g g-1 day-1), CGR (34.114 g m-1day-1), AGR (2.303 g day-1) at 60-90 DAS, LAI (3.34), SLW (1.23 g dm-2) and number of green leaves plant-1 (9.83) at 90 DAS than other genotypes and best check M 35-1. While, genotypes E-19, Phule Maulee, E-227, E-277 and PKV-Kranti also performed better for various morpho physiological and growth parameters. In biochemical analysis, the genotypes CSV-29R and E-19 at 90 DAS rewarded significantly higher proline content (4.38 and 23.40 µ mole g-1 FW), CSI (0.47 and 0.43%) and leaf nitrogen content (2.47 and 2.42%) respectively. Nitrogen content in seed (2.25 and 2.31 %), protein content in seed (14.06 and 13.05 %) and micro nutrients like, Zinc (17.20 and 15.93 mg kg-1) recorded maximum in the genotypes CSV-29R and E-19 respectively, while other seed micro nutrients i.e., Mn (5.68 and 5.45mg kg-1), Fe (46.43 and 44.25 mg kg-1) and Copper (1.80 and 1.65 mg kg-1) recorded significantly highest in genotypes E-19 and CSV-29R respectively, than other genotypes and checks at harvest. Phule Anuradha (check) and CSV-29R were found earlier in physiological maturity. In relation with yield and yield attributes, genotype CSV-29R and E-19 noted significantly highest panicle length (18.17 and 16.63 cm), panicle diameter (7.33 and 7.20 cm), earhead exertion (74.7 and 70.5 %), number of grains panicle-1 (1544 and 1478), grain weight plant-1 (22.95 and 20.67 g), test weight (32.62 and 30.62 g), grain yield (2393 and 2090 kg ha-1), biological yield (6308 and 5844 kg ha-1) and harvest index (37.96 and 35.76 %) respectively, than other genotypes and best check M 35-1. Among the three checks, M 35-1 recorded best in performance on the basis of all traits under study than other check genotypes viz. Phule Anuradha and Ringni in moisture stress under late sown rainfed condition. Current study was also erudite for the optimization of appropriate concentration of PEG for screening the genetic resource of rabi sorghum for further detailed studies. Various osmotic stress levels had substantial effects on germination and early vegetative growth traits of rabi sorghum genotypes. At highest concentration (-0.066 MPa) of osmotic (PEG) stress condition, genotypes M-35-1, E-277 and E-227 showed positive result for shoot length, root length and seedling dry weight. Germination per cent, seedling vigour, shoot length, root length, seedling dry weight and stress tolerance index also decreases with increase in osmotic stress. Considering the correlation coefficient on grain yield found positive and significant correlation with all morpho physiological, growth and biochemical parameters except plant height plant-1. While, yield has negative significant correlation with days to 50 % flowering and physiological maturity. Traits under study viz., may be used in the breeding programme for the development of moisture stress tolerant genotypes under late sown rainfed condition for changing climatic scenario.ThesisItem Open Access Morpho-physiological and biochemical response of rabi sorghum genotypes to moisture stress under late sown rainfed condition.(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-09-13) BOBADE, PRATIK NAGESH.; Amarshettiwar, Dr. S.

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.ThesisItem Open Access PHYSIOLOGICAL AND BIOCHEMICAL INVESTIGATION ON LEAF REDDENING IN Bt AND NON Bt COTTON ( Gossypium spp.)(Dr. Punjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra, 2016-12-31) RAUT, SUMIT MURLIDHAR; Durge, Dr. D. VThesisItem Open Access Physiological and biochemical investigation on leaf reddening in bt and non bt cotton (Gossypium spp.)(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2016-12-31) RAUT, SUMIT MURLIDHAR; Durge, Dr. D. V.Cotton IS an 1111portant commercial fib re crop of global significance which plays a dominant role in world ag riculture ancl industri al economy. India is important grower of cotton on a global scale. Among the productionconstrai nts leaf reddening is the predominant problem of Bt cotton growers which became issue of debet for ascertaining the causes and remedies for leaf reddening. To ascertain the role of nutrients in leaf reddening, the present field experiment entitled, "Physiological and biochemical investigation on leaf reddening in Bt and non Bt Cotton (Gossypium spp.)" was carried out at AICCP, experimental field of Cotton Research Unit, Dr. PDKV Akola, (M.S.) during Kharif season of 2013-14 and 2014-15 in split plot design replicated thrice. Main plot treatments consisted of three hybrids [viz., Mallika (Bt), RCH 2 (Bt) and PKV Hybrid 2 (non Bt)], sub plot treatments were two fertilizer doses [viz., 100% RDF and 125% RDF]. Sub-sub plot treatments consisted of seven different chemical sprays [viz., 2% Urea, 2% DAP, 2% KN03, 1% MgS04, 500 ppm Cycocel, irrigation and control]. Thus, 42 treatment combinations were formed. The fertilizer dose for Bt (120:60:60 NPK kg/ha) and non Bt cotton (60:30:30 NPK kg/ha) was applied in two split doses. At the time of sowing 50% N and full dose of P and K was applied and remaining N was applied after 30 DAS. The two foliar sprays were given at 60 and 80 DAS. The recommended package of practices was. followed during course of investigation. Besides the yield data, periodical observations on morphological (plant height, leaf area plant-1; dry matter plant-1 and red leaf incidence), physiological (photosynthetic efficiency and relative water content} and biochemical (cell sap pH, total chlorophyll, N, Mg, anthocyanin proline and carbohydrate content of leaf) parameters were recorded at 60, 80, 100 and 120 DAS. The Phenological observations were alsoc recorded Soil fertility status (available N, P and K) were recorded before sowing and after harvesting in both the years. The observations on sucking pest (number of leafhopper, aphids, thrips and whitefly leaf1) were also recorded. The experimental evidences pointed out that the incidence of leaf reddening was more in Bt cotton than non Bt colton. The minimum intensity of reddening in Bt and non Bt cotton was observed in the treatment combination of 125 % RDF +foliar sprays with KN03 and MgS04. Among the foliar sprays 2% KN03 (60 and 80 DAS) had shown minimum leaf reddening. However, the xiv treatment combination (125% RDF + 1 % MgS04) was found to be the best for highest total chlorophyll content. The study also revealed that the mineral nutrients, which were mostly responsible for reddening viz., nitrogen and magnesium content in leaves, were decreased as the crop growth stage advanced. The PKV Hybrid 2 ·recorded rna~imum cell sap pH, total chlorophyll, leaf nitrogen and magnesium content than the Bt cotton hybrids. In case of fertilizer dose, 125% RDF and foliar sprays of 2% KN03 and 1% MgS04 maintained higher cell sap pH, total chlorophyll, nitrogen, and magnesium content of leaves in non Bt cotton than Bt cotton. Accumulation of highest proline, anthocyanin and carbohydrate were found in reddening affected leaves. It was evident that, the application of 125% RDF showed 9.21 % reduction in leaf reddening incidence. Similarly 16.14% increased seed cotton yield per plant with application of 125% RDF over 100% RDF. Per cent reduction of red leaf incidence was recorded 18.33% in 2% KN03 treated plot followed by 1% MgS04 i.e. 14.76% over control. Seed cotton yield per plant was Increased by 39.33% in 2% KN03 treated plot followed by 1% MgS04 sprayed plot i.e. 31.88% over the control (untreated plots). Application of 125% RDF and the two foliar sprays of 2% KN03 and 1% MgSO~ at 60 and 80 DAS had reduced the risk of leaf reddening as well as helped in increasing seed cotton yield in Bt and non Bt cotton hybrids at Akola conditions. It is concluded from the present study that th.e reduction In chlorophyll, nitrogen and magnesium content in plant at boll development stage was the cause of reddening in Bt and non Bt cotton. This study also suggested that, the nutrients were one of the causes for leaf reddening. Bt cotton had more nutrients requirement especially at boll development stage, which was fulfilled by the foliar sprays. Hence, present study also provides future guide line of research for various combinations of nutrients for foliar sprays for Bt cotton hybrids at different development stages, which can reduce leaf reddening and there by yield sustainability can be achieved.ThesisItem Open Access STUDIES ON DROUGHT TOLERANCE IN RABI SORGHUM(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2008-11-18) BAND, PALLAVI EKNATHRAO; DURGE, D.V.ThesisItem Open Access POST HARVEST FUNGAL DISEASES OF MANDARIN, MANGO AND BANANA(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2014-12-12) INOOLE, MANOHAR NAMDEORAO; Gade, Dr. R.M.ThesisItem Open Access DROUGHT TOLERANCE STUDIES IN COTTON SPECIES(Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2013-12-24) AMARSHETTIWAR, SHRIKANT BALIRAM; Rathod, T.
