ThesisItem Open Access Assessment of air quality of indoor space through use of different indoor plants(CCSHAU, 2019) Santosh Kumari; Mehta, ManjuThe present study entitled ―Assessment of air quality of indoor space through use of different indoor plants‖. Air quality ―refers to the condition of the air within surrounding. The study was undertaken to know the existing practices and knowledge regarding the indoor plants adopted by homemakers in the house of Hisar city and assesses the indoor air quality through use of indoor plants. The study was carried out in two phases, survey work and experimental work. Survey work was carried out in five randomly selected locality of Hisar city. From each selected locality 30 homemakers were randomly selected from each thus making total sample 150 homemakers. Air quality meter, thermometer and lux meter were used for assessment of air quality of indoor spaces for four weeks in Gangotari hostel of CCSHAU, Hisar. For the experimental work six rooms were selected for assessment of indoor air quality of different rooms i.e.R1(spider plant), R2(rubber plant), R3 (bamboo palm), R4 (snake plant), R5(boston fern ) and one room was RC(control room) for comparison in air quality The study revealed that level of knowledge regarding indoor plants was medium (68.6%). The maximum homemaker used seasonal plants (60.0%) and 94% use indoor plants for aesthetic purpose. A significant correlation among the socio economic status and independent variables and the knowledge and independent variables was found. In all rooms where indoor plants were placed showed improvement in indoor air quality in case of formaldehyde, suspended particulate matter and volatile organic compound. After 4th week in control room formaldehyde increased 1.60 percent whereas, room with spider plant formaldehyde decreased by 74.07%, trailed by 73.30% decrease in room with bamboo palm. The suspended particulate matter after 4th week in control room increased by 70.92% but in room with spider plant it reduced by 50.02% trailed by 32.71% decrease in room with rubber plant. Volatile organic compound decreased in room with spider plant (63.41%), room with rubber plant (51.85%), room with bamboo palm(72.73%), room with snake plant(64.04%). The amount of light was less than recommended light in all experimental rooms. The relative humidity was increased in room with plants in comparison with control room, and relative humidity was higher than the recommended value. The temperature was increased according to the environmental change because the days were becoming warmer.ThesisItem Open Access Genetic evaluation of radish (Raphanus sativus L.) genotypes under low hill conditions of Himachal Pradesh(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2023-10-12) Shalini; Santosh KumariThe present investigation entitled “Genetic evaluation of radish (Raphanus sativus L.) genotypes under low hill conditions of Himachal Pradesh” was carried out during rabi season of 2022 at Experimental Farm of Department of Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur (H.P). Twenty five genotypes including check variety Japanese White were evaluated in Randomized Complete Block Design with three replications to estimate the extent of variability, heritability, genetic advance, correlation and path coefficient analysis for yield and other horticultural traits. Analysis of variance showed significant differences among the genotypes for all the horticultural traits studied. The genotypes LC-58, LC-57 and LC-53 recorded more yield over check variety Japanese White and also performed better for majority of other characters like number of leaves per plant, leaf length, average root weight with leaves, root length and dry matter content in roots, respectively. The estimates of phenotypic and genotypic coefficients of variation were high for ascorbic acid content in roots and root length. High heritability coupled with high genetic advance as per cent mean was observed for plant height, number of leaves per plant, crown diameter, average root weight with leaves, root length, root yield per plot, total soluble solids and ascorbic acid content in roots. The correlation studies at genotypic and phenotypic levels revealed that root yield per plot exhibited significant and positive correlation with average root weight with leaves, plant height, root length, days to marketable maturity, number of leaves per plant, leaf length, dry matter content in roots, total soluble solids, leaf width and crown diameter. The path coefficient analysis indicated that average root weight with leaves observed maximum positive direct effect on root yield per plot followed by leaf length, number of leaves per plant, ascorbic acid content in roots, plant height and total soluble solids. Therefore, selection for these traits would be more effective for improvement of root yield in radish.ThesisItem Open Access Studies on genetic variability in Okra [Abelmoschus esculentus (L.) Moench] under low hills of Himachal Pradesh(College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2023-10-18) Sharma, Akhilesh; Santosh KumariThe present investigation entitled “Studies on genetic variability in okra [Abelmoschus esculentus (L.) Moench] under low hills of Himachal Pradesh” was carried out during kharif season of 2022 at Experimental Farm of Department of Vegetable Science, College of Horticulture and Forestry, Neri, Hamirpur (H.P). Nineteen genotypes including check variety P-8 were evaluated in Randomized Complete Block Design with three replications to estimate the extent of variability, heritability, genetic advance, correlation and path coefficient analysis for yield and other horticultural traits. Analysis of variance revealed significant differences among the genotypes for all the horticultural traits studied. The genotypes LC-109, LC-101 and LC-102 recorded more yield over check variety P-8 and also performed better for majority of the characters viz., fruit length, fruit diameter, average fruit weight, number of fruits per plant and fruit yield per plot. The estimates of phenotypic and genotypic coefficients of variation were high for plant height and fruit yield per plant. High heritability coupled with high genetic advance as per cent mean was observed for plant height, number of fruits per plant, fruit yield per plant and fruit yield per plot. The correlation studies at genotypic and phenotypic levels revealed that fruit yield per plot exhibited significant and positive correlation with leaf length, leaf width, fruit length, plant height, fruit diameter, average fruit weight, number of fruits per plant, hundred seed weight, number of seeds per fruit, harvest duration and fruit yield per plant. The path coefficient analysis indicated that number of fruits per plant observed maximum positive direct effect on fruit yield per plot followed by fruit diameter, leaf length, average fruit weight,harvest duration, number of seeds per fruit and fruit yield per plant. Therefore, selection for these traits would be more effective for improvement of fruit yield in okra.ThesisItem Open Access Studies on preparation of sev using unripe banana(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-06) Sharma, Monika; Santosh KumariA study was undertaken to incorporate unripe banana pulp in sev preparation to enhance and diversify the uses of unripe banana in snack products. The sev prepared by incorporating different levels of unripe banana pulp were analyzed for their physical and sensory characteristics. Chemical analysis and cost evaluation of the optimized product were also carried out. The incorporation of unripe banana sev upto 90 per cent decreased the water uptake of blend from 32.5 to 1.4 ml per 100 g. The yield and oil absorption were reduced from 109.67 to 62.16 and 28.49 to 24.63 g per 100 g, respectively. The diameter and expansion ratio also showed a decreasing trend. On the basis of statistical analysis of the organoleptic qualities, the product with 85 per cent unripe banana was found to be significantly different from control and optimization of ingredients was done in this level. After optimization, an acceptable unripe banana sev was developed from the blend, containing spices (1.0 g red chilli powder, 1.0 g ajwain), common salt @2.0 g and hydrogenated vegetable fat @3.0 g. The scores for different sensory attributes were; colour/appearance (7.89), texture (7.89), taste (8.40) and overall acceptability (8.08). The optimized product had a fat content of 29.89 per cent as compared to control (33.99 per cent). The cost of the optimized product was 16.24 per cent less than the control sev.ThesisItem Open Access Study on green consumerism towards sustainable development(CCSHAU, Hisar, 2022-12) Santosh Kumari; Dua, KavitaGreen consumer is environmentally and socially conscious and very concerned about the environment and, therefore, only purchases products that are environmentally-friendly or eco-friendly. The present study was conducted in two districts of Haryana state i.e. Hisar and Bhiwani. Two blocks from each district were randomly selected. Further, 75 respondents from each village was selected randomly. Thus, total 4 villages were selected to conduct the study thus making total sample size of 300 respondents for objective 1. For objectives 3twenty five respondents having low pre-exposure knowledge and also who were willing to attend the trainings were purposively selected from each village. Thus, total respondents were 100 (25 from each village). Knowledge was imparted to 100 respondents by imparting trainings through lecture-cum-demonstration and through multimedia (booklet, leaflet, poster and videos) prepared by the researcher. After a period of one month, impact of trainings on these 100 respondents was assessed in terms of gain in knowledge. A well structured and pretested interview schedule was developed according to the objectives of the study. It was found that majority of respondents regarding socio economic status showed that 43.0% of respondents belong from upper middle class. Maximum of respondents (44.7.3%) had medium family education status. This shows that more than half (51.2%) of the respondents had overall low knowledge and awareness at pre-exposure stage. Majority of respondents did not follow the eco friendly practices while purchase products at pre exposure stage. The results show that highly significant gain in knowledge was observed in all the respondents regarding all aspects of green consumerism at post exposure stage and highly gain in knowledge was found in awareness about ordinary products responsible for environmental degradation (9.76) and eco friendly home appliances (12.82). Positive correlation was found in all independent variables at 1% level of significant with gain in knowledge.
