ThesisItem Open Access Diallel Analysis in Brinjal (Solanum melongena L.)(PhD)(SKNAU, 2011) Choudhary, SantoshThesisItem Open Access Diversity Studies in Round Gourd [Praecitrullus fistulosus (Stocks) Pangalo](Agriculture University, Jodhpur, 2020-07-16) Kumar, Sunil; Moond, S.K.; Choudhary, Santosh; Ram, MoolaA field experiment entitled “Diversity studies in Round gourd [Praecitrullus fistulosus (Stocks) Pangalo]” was carried out at the College of Agriculture, Jodhpur (Rajasthan). The experiment was laid out in Randomized Block Design with three replications during Kharif 2019 on 20 different genotype of round gourd including two check cultivars, to estimate the extent of genetic variability, heritability, genetic advance, correlation among the yield and other attributing traits, direct and indirect effect of yield contributing traits through path coefficient analysis and genetic divergence through D2 statistics. Analysis of variance (ANOVA) exhibited significant differences for all the studied characters suggesting the presence of great inherent genetic variation amongt the genotypes. The phenotypic coefficients of variation were slightly higher than the respective genotypic coefficients of variation for all the characters under study. High estimates of heritability were noted for almost all the traits except days taken to 50% female flowering, leaf area and days to anthesis of first female flower. High heritability and high genetic advance as per cent of mean were observed for the traits of main vine length at harvest, number of marketable fruits per plant, fruit yield per plant, fruit yield per hectare, fruit yield per plot, node on which first male flower appeared, fruit diameter, shelf life and rind thickness, suggesting additive gene action for expression of these characters. Hence, these characters may prove effective for selection to improve fruit yield per plant in round gourd. Correlation studies among the characters revealed that fruit yield per plant had significant positive association with the characters like number of leaves par plant, main vine length at harvest, internodal length, leaf area, number of marketable fruits, fruit diameter, fruit weight, rind thickness and shelf life both at phenotypic and genotypic levels. Path coefficient analysis of various quantitative characters indicated that main vine length at harvest, internodal length, days to anthesis of first female flower, days taken to 50% female flowering, number of marketable fruits per plant, fruit diameter, fruit weight and rind thickness exhibited positive direct effect on fruit yield per plant. Based on the relative magnitude of D2 values, Tocher’s method resulted in formation of three clusters. Out of the three clusters, cluster I was the largest comprising of fifteen genotypes followed by II with four genotypes while the cluster III was monogenotypic, suggesting the existence of high degree of heterogeneity between the genotypes. The trait of fruit shelf life contributed the maximum towards genetic divergence. The highest intra-cluster distance was recorded in the cluster II, while the inter-cluster distance was the highest between cluster I and II, followed by cluster II and III, indicating that superior recombinants could be obtained by mating between genotypes of these clusters.ThesisItem Open Access Effect of Foliar Fertilization of NPK on Growth and Yield of Carrot (Daucus carota L.) in Loamy Sand Soil of Rajasthan(Agriculture University, Jodhpur, 2021-07-08) Chouhan, Rakesh; Choudhary, Santosh; Moond, S.

The experiment consisted 12 treatments viz., control, 2 ml/l nano urea, 4 ml/l nano urea, 50% RDN, 50% RDN + 2 ml/l nano urea, 50% RDN + 4 ml/l nano urea, 75% RDN, 75% RDN + 2 ml/l nano urea, 75% RDN+ 4 ml/l nano urea, 100% RDN,100% RDN + 2 ml/l nano urea and 100% RDN + 4 ml/l nano urea, and was laid out in Randomized Block Design (RBD) with three replications. The results of the study clearly indicate that application of 100% RDN + 4 ml/l nano urea recorded the highest plant height, number of branches per plant, internodal length, total number of cuttings and minimum number of days taken for first cutting and shortest average cutting interval over the control. The treatment 75% RDN + 4 ml/l nano urea remained at par with 100% RDN + 4 ml/l nano urea. Quality parameter of Nagauri methi like iron content of leaves, chlorophyll content, protein contents of leaves and seed were significantly higher with application of 100% RDN + 4 ml/l nano urea over the control and statistically at par with 75% RDN + 4 ml/l nano urea. The lowest values of these parameters were recorded with control treatment. The maximum fresh and dry herb yields and seed yield were recorded markedly higher with application of 100% RDN + 4 ml/l nano urea, being statistically at par with 75% RDN + 4 ml/l nano urea. The lowest values of these parameters were recorded with control treatment. Significantly higher net returns (₹ 322565/ha) and B:C ratio (3.05) were obtained with application of 75% RDN + 4 ml/l nano urea over the control followed by 100% RDN + 4 ml/l nano urea net returns (₹ 322540/ha) and B:C ratio (3.04). Hence, 75% RDN + 4 ml/l nano urea application can be beneficial for producing higher productivity and net returns of Nagauri methi in western Rajasthan.ThesisItem Open Access Effect of Sowing Date, Row Spacing and Nitrogen Levels on Productivity of Garden Cress (Lepidium sativum L.)(PhD)(SKNAU)(SKNAU, 2009) Choudhary, SantoshThesisItem Open Access Effect of Spacing and Training Method on Growth and Yield of Off-season Ridge Gourd (Luffa acutangula L.)

Varieties in Arid Region of Rajasthan(Agriculture University, Jodhpur, 2019-05-28) Somveer; Choudhary, Santosh; Moond, S.K.; Raiger, P.R.A field experiment was conducted at College of Agriculture, Mandor, Jodhpur during the Kharif season of 2018, to find out the suitable variety and its optimum sowing time and spacing for higher yield, quality and net returns of carrot in western Rajasthan. The treatments comprising two varieties (‘Pusa Rudhira’ and ‘Pusa Vrishti’), three spacing (20 cm × 10 cm, 30 cm × 10 cm and 30 cm × 20 cm) and four dates of sowing (10th August, 25th August, 10th September and 25th September) allocated in Factorial Randomized Block Design with three replications. Experiment results revealed that variety ‘Pusa Vrishti’ recorded significantly higher growth parameters while ‘Pusa Rudhira’ recorded significantly higher yield parameters, root yield (23.8 t ha-1), quality parameters and net returns (Rs. 2,55,491) with lesser days to marketable maturity (73.9). Among different spacing, significantly higher growth and yield parameters were observed in widest spacing (30 cm × 20 cm). However, root yield (24.5 t ha-1) and net returns (Rs.2,26,604) were recorded highest in S1 (20 cm × 10 cm). The 25th September sowing recorded significantly highest growth parameters, yield parameters, yield (25.8 t ha-1) and quality parameters besides being earliness in term of maturity (73.7 days). However, the highest net returns (Rs. 3,09,028) and B:C ratio (4.33) were recorded in 10th August sowing. The combination of ‘Pusa Vrishti’ sown on 25th September, recorded highest plant height at 60 DAS (39.3 cm) and fresh weight of aerial part (101.9 g) whereas, ‘Pusa Rudhira’ sown on 25th September combination recorded significantly higher values of fresh weight of root (139.4 g), root yield (11.1 kg plot-1) and root yield (25.8 t ha-1). Hence, variety ‘Pusa Rudhira’ sown in closer spacing of 20 cm × 10 cm spacing under staggered sowing is found to be superior in terms of yield, quality, earliness and net returns in the arid regions of Rajasthan.ThesisItem Open Access Effect of Zinc and Iron Application on Growth and Yield of Garlic (Allium sativum L.)(Agriculture University, Jodhpur, 2022) Kuri, Ronak; Choudhary, SantoshA field experiment was conducted at Instructional Farm, College of Agriculture, Jodhpur to assess the “Effect of zinc and iron application on growth and yield of garlic (Allium sativum L.)” during Rabi, 2021-22. The experiment comprised 13 treatments consisting of three levels each of ZnSO4 and FeSO4 at 5, 10 and 15 kg/ha as soil application and three levels of each as a foliar application at 0.3, 0.5 and 0.7% concentration at 60 and 90 DAP and control. The experiment was laid out in a randomized block design with three replications. The results revealed that all the growth parameters, yield parameters, quality attributes, and economics of garlic were influenced significantly by different levels of soil and foliar application of ZnSO4 and FeSO4. Among the different levels of Zn, soil application of ZnSO4@15 kg/ha and foliar application of ZnSO4@0.7% being at par with ZnSO4@10 kg/ha and ZnSO4@0.5%, respectively recorded significantly higher growth and yield attributes over control. Therefore, the growth and yield parameters under ZnSO4@15 and 10 kg/ha; and ZnSO4@0.7 and 0.5% were recorded statistically at par with each other. Further, among different levels of Fe, soil application of FeSO4@15 kg/ha and foliar application of FeSO4@0.7%, being at par FeSO4@10 kg/ha and FeSO4@0.5%, respectively recorded significantly higher growth and yield attributes over control. Similar to Zn levels, FeSO4@15 and 10 kg/ha, and FeSO4@0.7 and 0.5% recorded growth, yield and quality parameters statistically at par with each other. A significant residual effect of ZnSO4 and FeSO4 in soil was recorded with soil application of both nutrients. The highest net returns (`4,65,154/ha) were obtained from foliar application of ZnSO4@0.7%; whereas the highest B: C ratio (3.08:1) was obtained from soil application of ZnSO4@15kg/ha. Moreover, with soil and foliar application of FeSO4 highest net returns (`4,32,621/ha) and B: C ratio (2.84:1) were recorded with FeSO4@0.7% over control and other treatment of FeSO4. Hence, soil application of Zn and Fe by ZnSO4 and FeSO4@15 kg/ha or their foliar application at 0.7% concentration can be beneficial for producing higher productivity and net returns of garlic in western Rajasthan.ThesisItem Open Access Evaluation of Sweet Pepper (Capsicum annum L.

The maximum stem diameter at harvest was found in „Pusa Deepti‟ (17.3mm). Genotype „Pusa Deepti‟ recorded the maximum fruit length (9.74cm) and number of fruits per plant (19.53) whereas, „Orobelle‟ recorded the maximum fruit diameter (6.00cm). The genotype „Indra‟ was observed with earliest 50% flowering (68.0 days), maximum fruit weight (75.13g), fruit yield per plant (1.345kg), fruit yield per 1000m2 (48.8q) and pericarp thickness (0.60cm). whereas, „Orobelle‟ recorded the highest crop duration (221 days). The maximum number of locules per fruit (4.80) was found in „Ganga‟. In terms of quality parameters, the genotype „Arka Gaurav‟ recorded maximum ascorbic acid (168.6mg/100g) and total soluble solids content (7.53%)‟. The genotype „Indra‟ was observed with maximum shelf-life (8.6 days). The „Indra‟ was identified as remunerative genotype exhibiting highest net returns (`1,04,666/-) and B:C ratio (2.51) per 1000 m2 area. Hence, considering the highest fruit yield genotype „Indra‟ was found to be economically remunerative option for growing sweet pepper under modified net house to improve the socio economic and nutritional status of farmers under western Rajasthan conditions.ThesisItem Open Access Genetic Variability and Divergence Study for Seed Yield and it’s Components in Pearl Millet [Pennisetum glaucum (L.) R. Br.](Agriculture University, Jodhpur, 2019-05-24) Yadav, Shankar Lal; Rajpurohit, B.S.; Choudhary, B.R.; Choudhary, SantoshAn experiment entitled “Genetic Variability and Divergence Study for Seed Yield and it’s Components in Pearl Millet [Pennisetum glaucum (L.) R. Br.]” was carried out during Kharif 2018 at the Research Farm of Project Coordinating Unit, AICRP on Pearl Millet, Mandor, Jodhpur. The experiment was laid out in Randomized Block Design (RBD) with 30 genotypes and three replications to estimate the extent of genetic variability, heritability, genetic advance, correlation coefficient, path coefficient analysis and genetic divergence among all the genotypes. Analysis of variance showed highly significant variance among the genotypes for all the characters, under study, indicated availability of wide spectrum of variability among the genotypes. The phenotypic coefficient of variation (PCV) was slightly higher than the respective genotypic coefficient of variation (GCV) for all the characters under study indicated less influence of environment on the genotypes in expression of traits. Highest magnitudes of PCV and GCV were observed for zinc content whereas, the lowest PCV and GCV were observed for days to maturity. High estimate of heritability along with high genetic advance as percentage of mean were observed for days to 50% flowering, plant height, number of productive tillers per plant, panicle length, panicle diameter, stover yield per plant, grain yield per plant, 1000 grain weight, harvest index, iron content and zinc content indicated role of additive gene action for expression of these characters and are proven important for improving seed yield. High heritability values with moderate genetic advance as percentage of mean were observed for days to maturity and protein content. The grain yield per plant was found positively correlated with plant height, panicle diameter, stover yield per plant, 1000 grain weight and harvest index which showed that these traits are may be the selection criteria in breeding programme for improvement of seed yield. Path coefficient analysis revealed that stover yield per plant, harvest index, plant height and 1000 grain weight were the important characters for selection of high yielding accessions as they exerted high positive direct effect as well as showed positive significant correlation with grain yield per plant. Based upon the genetic variability, heritability, genetic advance as percentage of mean, correlation and path analysis it was concluded that stover yield per plant, grain yield per plant, harvest index, number of productive tillers per plant, panicle diameter and panicle length are most important yield components in pearl millet breeding programme. Based on the relative magnitude of D2 values resulted through Tocher’s method the genotypes were grouped in six clusters. Out of six clusters, cluster I was the largest comprising of 25 genotypes followed by mono genotypic cluster II, III, IV, V and VI. This suggested the existence of high degree of diversity among the genotypes. The trait iron content contributed maximum towards genetic divergence. The intra cluster distance was recorded in cluster I. The inter cluster distance was highest between cluster IV and VI followed by cluster V and VI, and III and VI indicated that superior recombinants can be achieved by crossing between the genotypes RIB-17/009 x RIB-15177, J-2405 x RIB-15177 and RIB-335/04 x RIB 15177 in a definite fashion.ThesisItem Open Access Genetic Variability and Path Coefficient Analysis Study in Cauliflower (Brassica oleracea L. var. botrytis) Under Arid Climatic Conditions(Agriculture University, Jodhpur, 2023-09-10) Nehra, Nitu; Choudhary, SantoshA field experiment on “Genetic Variability and Path Coefficient Analysis Study in Cauliflower (Brassica oleracea L. var. botrytis) Under Arid Climatic Conditions” was carried out during Rabi, 2022-23 at the Instructional Farm of the College of Agriculture, Jodhpur (Rajasthan). The experiment was laid out in Randomized Block Design with 16 genotypes and three replications to estimate the extent of genetic variability, heritability, genetic advance, the correlation between yield and other characters, the direct and indirect effect of yield contributing traits through path analysis. Significant differences in the analysis of variance for each attribute indicated that there are great inherent genetic variances among the genotypes. For each of the investigated traits, the phenotypic coefficient of variance was slightly greater than the corresponding genotypic coefficient of variation. High estimates of heritability and genetic advance as per cent of mean were observed for the characters viz., curd yield per plant followed by curd yield per plot, curd yield per hectare, ascorbic acid, days to 50% curd initiation, days to 50% curd maturity, plant height, leaf width, leaf length, curd circumference. The moderate heritability was recorded for SPAD Unit, curd width and plant spread. Correlation coefficient analysis among the traits studied revealed that curd yield per plant has a strong positive significant association with characters like plant height, plant spread, leaf length, leaf width, days to 50% curd initiation, days to 50% curd maturity, curd circumference, curd width, ascorbic acid and SPAD Unit. Path coefficient analysis of various quantitative characters indicated that cured width, days to 50% curd initiation, days to 50% curd maturity, ascorbic acid and curd circumference exhibited a positive direct effect on curd yield per plant while, plant height exhibited the maximum negative direct effect on curd yield per plant. Based on yield and yield attributes, among varieties Sabour Agrim and in hybrids Fortaleza were found superior and can be recommended for testing in large environments to check its suitability for growing in arid region of RajasthanThesisItem Open Access Genetic Variability, Character Association and Path Analysis Study in Sweet Potato [Ipomoea batatas (L.)

Moench)” was carried out during August 2019 to November 2019 at the Instructional Farm, College of Agriculture, Jodhpur (Rajasthan). The experiment comprised of 12 varieties and hybrids of okra viz. „P-8‟, „Pusa Bhindi-5‟, „Samrat F1 Hybrid‟, „Punjab Suhawani‟, „Arka Nikita‟, „Shakshi F1 Hybrid‟, „Palam Komal‟, „Kashi Kranti‟, „Shakti F1 Hybrid‟, „Arka Anamika‟, „Kashi Pragati‟ and „Laxmi F1 Hybrid‟ and was laid out in Randomized Block Design with three replications. Significant differences were found amongst the varieties and hybrids of okra for the studied characters. The „Arka Anamika‟ recorded the maximum number of branches per plant (2.80), stem diameter (17.10 mm), number of leaves per plant (69.06), number of fruit per plant (25.80), fruit yield per plant (369.78), fruit yield per plot (4.95 kg) and estimated fruit yield per hectare (122.23 q). The „Palam Komal‟ recorded the maximum plant height (139.73 cm) and numbers of nodes on main stem (30.80) while „Laxmi F1 Hybrid‟ produced the largest leaves (156.86 cm2 ). The earliest first flower anthesis (39.67 DAS) and 50% flowering (39.33 DAS) and first picking (45.40 DAS) were recorded in „Kashi Pragati‟, whereas the maximum fruit length was recorded in „Pusa Bhindi-5‟ (12.36 cm). The „Samrat F1 Hybrid‟ recorded the maximum fruit diameter (16.02 mm) and fruit weight (12.99 g) while the longest shelf life of fruit was obtained in „Kashi Kranti‟ (4.47 Days). Fruits of all the varieties and hybrids were dark green in colour with hairy appearance and five ridges except „Arka Anamika‟ which produced green colour fruits. Analysis of variance exhibited significant differences for all the characters which shoed the presence of abundant inherent genetic variation among the genotypes. The phenotypic coefficients of variation were higher than the respective genotypic coefficients of variation for all the characters under study. High estimates of heritability were observed for leaf area followed by days taken to first anthesis, fruit yield per hectare, fruit yield per plot, stem diameter, days taken to first picking, shelf life of fruit, fruit yield per plant, days taken to 50% flowering and number of fruits per plant. Genetic advance as percent of mean (genetic gain) ranged from 29.44 % for yield per hectare to 5.78 % for fruit length. High genetic advance was recorded for fruit yield per plant, fruit yield per hectare and leaf area.ThesisItem Open Access ThesisItem Open Access To Study Performance of Brinjal (Solanum melongena L.)

The experiment comprised of twelve brinjal cultivars and hybrids viz. „Pusa Hybrid-5‟, „Pusa Shyamla‟, „Pusa Hybrid-6‟, „Pusa Upkar‟, „Pusa Kaushal‟, „Pusa Uttam‟, „Pusa Hybrid-9‟, „Pusa Anupam‟, „Soyla Local‟, „MAHY 80‟, „MAHY Kalpataru‟ and „Sungro F1 Hybrid Brinjal No. 117‟ and was laid out in Randomized Block Design with three replications. Significant differences were found amongst the cultivars and hybrids of brinjal for the studied characters. The „Pusa Hybrid-5‟ recorded the maximum plant height (106.67 cm), while the maximum numbers of primary branches plant-1 (8.73) and number of leaves plant-1 (288.13) were recorded in „Pusa Anupam‟. The „MAHY 80‟ produced the largest leaves (156.68 cm 2 ). The „Pusa Hybrid-9‟ recorded the maximum stem girth (49.72 mm) and plant dry weight (211.14 g), while the maximum plant fresh weight (761.43 g) in „Soyla Local‟. The earliest first flower bud formation (26.93 DAT) and 50% flowering (35.0 DAT) were noted in „Pusa Hybrid9‟. The „Pusa Uttam‟ produced the maximum number of clusters plant-1 (52.40), while „Pusa Kaushal‟ produced the maximum number of flowers cluster-1 (6.93) but the maximum number of fruits cluster-1 (1.09) was produced in „MAHY 80‟. The „Pusa Hybid-6‟ produced the maximum number of fruits plant-1, highest fruit yield plant-1 , highest fruit yield plot-1 and estimated highest fruit yield ha-1 (36.20, 1.65 kg, 32.21 kg and 509.69 q, respectively). The maximum fruit diameter (5.02 cm) was recorded in „MAHY 80‟ at marketable stage and „Pusa Upkar‟ (8.59 cm) at physiological maturity stage. The „Pusa Hybrid-5‟ had the longest fruit length at both marketable stage (14.07 cm) and physiological maturity stage (17.07 cm). The heaviest fruits at marketable stage were observed in „MAHY 80‟ (72.74 g) and at physiological maturity stage in „Sungro F1 Hybrid Brinjal No.117‟ (234.0 g). Fruits of all the cultivars and hybrids were non-spiny except „Soyla Local‟ and „MAHY Kalpataru‟. The fruits having highest TSS (5.10 ºBrix) were noted in „Pusa Hybrid-6‟. The highest crop growth rate was observed in „Sungro F1 Hybrid Brinjal No. 117‟ (11.71 g m-2 day-1), while the highest net assimilation rate (0.285 mg cm-2 day-1) in „Pusa Uttam‟. The brinjal „Pusa Hybrid-6‟ resulted as the highest yielder under shade-net house conditions in off-season of western Rajasthan providing the highest net returns (Rs. 23,332 per 500 m2 area) and B:C ratio (1.84) followed by „Pusa Hybrid-9‟and „MAHY 80‟. * Post-graduate student, Department of Horticulture, College of Agriculture, Jodhpur. ** Assoc.
