ThesisItem Open Access EFFECT OF DIFFERENT SOURCES OF SULPHUR ON YIELD, QUALITY OF CAULIFLOWER AND SULPHUR FRACTIONS IN AN ACID ALFISOL(CSKHPKV Palampur, 2016-07) NEHA; Sharma, Sanjay KA field experiment was conducted during rabi 2014-15 on cauliflower (Brassica oleracea L. var. Palam Uphar) at the experimental farm of Department of Soil Science, College of Agriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. The experiment consisted of three levels (12.5, 25, 37.5 kg S ha-1) and four sources (Sartaj natural gypsum, locally available gypsum, elemental sulphur and single super phosphate) of sulphur along with one control in a randomized block design. The application of sulphur @ 37.5 kg S ha-1 influenced growth parameters, yield attributes, quality, harvest index and per cent marketable curds significantly over 12.5 kg S ha-1. Likewise, highest net curd yield (113 q ha-1) was recorded with the application of 37.5 kg S ha-1, which was however, statistically at par with that obtained with the application of 25 kg S ha-1 (105.2 q ha-1) but significantly superior to that obtained with the application of 12.5 kg S ha-1 (89.5 q ha-1). Control recorded the lowest net curd yield (77.8 q ha-1). Among sources, Sartaj gypsum recorded maximum value of all these parameters followed by single super phosphate, locally available gypsum and elemental sulphur. Likewise, Sartaj gypsum recorded highest net curd yield (114.2 q ha-1) which was however, statistically at par with single super phosphate (102.9 q ha-1). The uptake of N, P, K, S, Fe, Mn, Cu and Zn by cauliflower increased with increased level of sulphur and followed the yield trend. Among sources, Sartaj gypsum recorded maximum nutrient uptake by cauliflower followed by single super phosphate. The different levels and sources of sulphur did not show any significant effect on soil pH, organic carbon, available K, Fe, Mn, Cu and Zn but had a significant effect on soil available N and P content. In case of fractions, available, water soluble, organic and total sulphur increased significantly with increased levels of sulphur. Sartaj gypsum recorded maximum value of available sulphur (12.4) and water soluble (9.8) followed by single super phosphate, locally available gypsum and elemental sulphur. Different sources of sulphur did not show any significant effect on heat soluble sulphur, organic sulphur and total sulphur. All sulphur fractions were significantly and positively correlated with yield, quality of cauliflower and sulphur fractions. However, higher correlation values were observed with water soluble and available sulphur and least with heat soluble sulphur. Maximum gross returns, net returns per hectare and gross returns per rupee invested were found when sulphur was applied @ 37.5 kg S ha-1 (Rs. 113083, 62286, 2.23, respectively) which was significantly superior to 12.5 kg S ha-1 (Rs. 89417, 40921, 1.84, respectively) but at par with 25 kg S ha-1(Rs. 105333, 55688, 2.13, respectively).ThesisItem Open Access FINANCIAL ANALYSIS OF HIMACHAL PRADESH TOURISM DEVELOPMENT CORPORATION(UHF,NAUNI, 2019-07) NEHA; KATHURIA, KAPILABSTRACT HPTDC has played a vital role in the development of tourism in state. However, HPTDC was not able to continue the initial momentum and hence had run into losses. The present study is an attempt to analyze its financial performance. Secondary data was collected from annual reports of HPTDC. Itprovides insights into widely used financial tool ratio analysis. The objective of the note is to help the reader understand how these ratios should be used to analyze the financial position of a firm. The findings of the study reveal that current ratio & quick ratio are below standard form that is current ratio 0.949 & 0.931 is quick ratio which is below 2:1 and 1:1. The net profit of HPTDC was 1.919 in 2016 which is fluctuating every year. The poor financial performance and improper utilization of resources by Himachal Pradesh Tourism Development Corporation which is running into losses for past many years. It is suggested to control the cost of goods sold and operating expenses. HPTDC should try to match the amount of working with the sales trends. To strengthen the financial efficiency, long-term funds have to be used to finance core current assets and a part of temporary current assets.ThesisItem Open Access GENETIC VARIABILITY FOR YIELD AND ITS ATTRIBUTES IN PUMPKIN (Cucurbita moschata Duch. ex Poir.)(DEPARTMENT OF VEGETABLE SCIENCE COLLEGE OF HORTICULTURE BANDA UNIVERSITY OF AGRICULTURE & TECHNOLOGY BANDA-210001, UTTAR PRADESH, (INDIA), 2023-08-14) NEHA; Ajeet SinghThesisItem Open Access IN VITRO SCREENING OF APPLE ROOTSTOCK M7 REGENERANTS AGAINST DEMATOPHORA NECATRIX HARTIG(COLLEGE OF HORTICULTURE DR.

Application of K @ 50, 100 and 150 per cent of recommended dose increased plant height, dry matter accumulation, total and effective tillers per metre row length, grains per ear and test weight significantly. Similarly, application of Zn (10 kg ha-1 ) and B(1 kg ha-1 ) influenced these growth and yield attributes of wheat significantly. Highest grain (42.52q ha-1 ) and straw (66.80q ha-1 ) yield of wheat was recorded under 150 per cent of recommended dose of K. Application of 150 percent of recommended dose of K increased grain and straw yield by 43.7 and 46.9 per cent over no K, respectively. Application of Zn (10 kg ha-1 ) increased grain and straw yield by 10.9 and 9.8 per cent over no Zn, respectively. The increase in grain and straw yield with the application of B (1 kg ha-1 ) was 5.6 and 6.3 per cent, respectively. Application of K increased N, P, K, Mn, Fe, Cu and B contents significantly at maximum tillering and harvesting. Application of Zn increased Zn and B contents significantly at both the stages but the contents of Fe, Mn and Cu decreased. However, B increased the contents of Zn and B only at maximum tillering stage and Zn, Mn and B at harvesting (grain and straw). Almost similar effects of K, Zn and B application on total nutrient uptake were observed. Application of Zn increased partial factor productivity, physiological efficiency, agronomic efficiency and apparent recovery. B application increased partial factor productivity and apparent recovery only. Application of K, Zn and B increased available K, DTPA extractable Zn and available B content significantly, respectively.ThesisItem Open Access MORPHOLOGICAL CHARACTERIZATION AND DISEASE REACTION STUDIES IN CAULIFLOWER(UHF.NAUNI, 2022-09) NEHA; MEHTA, D KABSTRACT The present investigation entitled “Morphological Characterization and Disease Reaction Studies in Cauliflower” was carried out at the Research Farm of Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Rabi season 2020- 21. Thirty genotypes of cauliflower including check variety PSBK-1 were evaluated for morphological characters based on DUS, horticultural traits and disease reaction to black rot and stalk rot which were further analysed in completely randomized design. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The genotypes were morphologically classified based on twenty one DUS characters. This variation is useful in identification of superior genotypes for inclusion in breeding programmes or direct use as a cultivar. Furthermore, association of any of these morphological characters with desirable traits or yield components can serve as a phenotypic marker in the selection process. Analysis of variance for horticultural traits revealed significant differences among all the genotypes for most of the characters under study. Mean performance of genotypes for various traits revealed that genotype Pusa Himjyoti recorded the highest marketable curd yield per hectare and genotypes Snowball Super, White Heart, UHF-CAU-1, Early Snowball, UHF-CAU-4, UHF-CAU-8 and KT-18 were found to be statistically at par with Pusa Himjyoti. All these genotypes have white to snow white curd with self- blanching habit. High heritability along with moderate genetic advance as per cent of mean was recorded for net curd weight indicating the occurrence of additive gene action. High heritability along with low genetic advance as per cent of mean was observed in plant height, leaf length, plant spread, stalk length and gross plant weight indicating the prevalence of non-additive gene interaction for these traits. Correlation coefficient revealed that the number of leaves per plant, plant spread, curd polar diameter, curd equatorial diameter, curd size index, curd solidity, gross plant weight and net curd weight were significantly and positively correlated with marketable curd weight. Thus, selection of these traits may be effective for selecting superior genotypes with high marketable curd weight. The maximum positive direct effect on marketable curd weight was contributed by curd equatorial diameter followed by curd polar diameter, net curd weight, curd solidity and number of leaves per plant. Thus, improvement in these characters will lead to higher yield in cauliflower. In case of disease reaction studies, no genotype was found resistant to stalk rot but in case of black rot, only one genotype White Heart was found resistant whereas Snowball Super and PSBK-1 showed moderately resistant reactionThesisItem Open Access STUDIES ON DEVELOPMENT OF PROTOCOL FOR FROZEN BUTTON MUSHROOM (Agaricus bisporus (Lange) Sing.)(PAU, 2013) NEHAIn this study, Agaricus bisporus strains P-1 and U-3 were cultivated on long method compost. Strain U-3 was higher yielder (14.31 kg/100 kg) than strain P-1. The freshly harvested mushrooms were subjected to different washing treatments [plain water, citric acid (0.5%), potassium metabisulphite (0.05%) or combinations of these washings with blanching (40 sec) ] prior to quick freezing at -350C (10 mins), packing in polypropylene bags and storing at -18ºC. Observations were made on physical (color and texture), microbiological (bacterial count) and biochemical (polyphenol oxidase enzyme, carbohydrates, fat and proteins) properties every month. The results of color measurement of L* value decreased gradually during storage. There were significant differences in the overall color difference ( E) calculated on the basis of the L, a and b values and E was least for the treatment of blanching + CA+ KMS. Texture analysis showed that hardness decreased gradually in both strains U-3 and P-1 during storage but was acceptable upto two months of storage. Maximum hardness (1361.02 gm in U-3 and 1257.47 gm in P-1) was recorded in treatment T7 (Blanching + CA + KMS). There was no microbial spoilage in fruit bodies packed and freezed in any of the treatments but activity of polyphenol oxidase (PPO) enzyme increased gradually. The minimum PPO activities (0.036 U.min-1 gm-1 in U-3 and 0.038 U.min-1 gm-1 in P-1) were observed in treatments T6 (Blanching + KMS), T7 (Blanching + CA + KMS) and T8 (KMS + KMS). Nutritional analysis of the frozen fruit bodies showed that there was there was a minimal decrease in total sugars, lipids and protein content in both the strains compared to freshly harvested mushrooms. However, during the storage period no significant changes in these nutritional components was observed.ThesisItem Open Access STUDIES ON POSTHARVEST HANDLING OF DAHLIA(Dahlia variabilis Willd.) cv. ‘GIANI ZAIL SINGH’(UHF,NAUNI, 2016) NEHA; SHARMA, B.P.ABSTRACT The investigation entitled, “Studies on postharvest handling of dahlia (Dahlia variabilis Willd.) cv. ‘Giani Zail Singh’” were carried out at the Experimental Farm and Laboratory of Department of Floriculture and Landscape Architecture, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni-Solan in the year 2015-2016. During the studies, three experiments viz. Standardization of different pulsing solutions; wrapping materials & storage durations and holding solutions on post harvest life of dahlia cv. ‘Giani Zail Singh’ were conducted separately. Pulsing solutions experiment was laid out in Completely Randomized Design with 10 treatments and 3 replications. It was observed that pulsing solution comprising of Sucrose 10 % + 8-HQC (400 ppm) + BA (50 ppm) for 16 hours improved the postharvest parameters such as amount of pulsing solution consumed (11.56 ml), amount of vase solution consumed (44.37 ml), appearance of cut bloom (4.72), flower diameter (12.75 cm), vase life (8.70 days) and minimum weight change (6.01 %) of the cut stems. An experiment of 7 wrapping materials and 4 storage durations was laid out in Completely Randomized Design (Factorial) with 3 replications. Wrapping of cut stems in cellophane and stored for 24 hours at 40 C increased the flower quality and longevity. Holding solutions experiment was laid out in Completely Randomized Design using 13 treatments and 3 replications. Holding solution comprising of Sucrose 2 % + NaOCl (25 ppm) improved different postharvest parameters such as amount of solution consumed (59.08 ml), appearance of cut bloom (4.56), flower diameter (13.21 cm), vase life (9.25 days) and minimum weight change (13.64 %) of the cut stems.
