ThesisItem Open Access Rain water harvesting in rural and urban families of Haryana(CCSHAU, 2014) Bhutani, Anshul; Sehgal, BinooWater is an essential natural resource for sustaining life and environment. The available water resources are under pressure due to increasing demands and the time is not far when water, which we have always thought to be available in abundance and free gift of nature, will become a scarce commodity. Conservation and preservation of water resources is urgently required to be done. Hence, the present study attempts to access the knowledge and perception regarding rain water harvesting and its utilization technologies among the urban and rural respondents. Training on RWH and its utilization technologies was also provided by setting up of a demonstration unit. The study was conducted in four phases. In phase I, survey was done on 150 urban and rural women respondents each to study the knowledge regarding rain water harvesting and its utilization technologies. In phase II, demonstration unit was set up on RWH and its utilization technologies. In phase III, training was imparted to thirty interested women respondents each from urban and rural areas on rain water harvesting and its utilization technologies. In phase IV, strategies were formulated for the propagation of these technologies. Results reveal that urban families were found to be consuming more quantity of water in all the household activities as compared to rural families as urban localities received water supply for 2 hours or less twice a day while in contrast to this rural areas received it for 1 hour or less once a day or on alternate day. Maximum water was consumed for flushing (178.3±41.8 litres) in urban localities and for bathing (61.5±26.3 litres) in rural areas. Nearly half of the respondents (52.3%) had awareness about rain water harvesting technology. No awareness with regard to the two rain water utilization technologies i.e. double-walled pot and pitcher irrigation was found among the respondents as these were new to the respondents. Rain water harvesting structure was got constructed outside the back gate of College of Home Science, CCSHAU, Hisar to collect rain water from one suitable roof of the college building. Volume of the tank is 1800 cu. ft and capacity of the tank to store rainwater is 50,958 litres. Two rain water utilization technologies i.e. double-walled pot and pitcher irrigation were selected for the study and demonstration unit of these were set up in the enclosure of Domestic Farm Unit, Deptt. of FRM, COHS, CCSHAU, Hisar. One year old flowering plant, Tabernaemontana divaricata (Crape Jasmine) was undertaken for the study. Least amount of water (19.5 litres) was consumed by the plant in the treatment T4 (Double-walled pot with mulch and cardboard ring). The water saving through this treatment came out to be maximum i.e. 34.7 per cent as compared to control (Tc). The total amount of water consumed by the plant planted through Pitcher Irrigation was 33.1 litres whereas the total amount of water consumed by the plant planted through conventional method (control) was 61.8 liters and the water saving through Pitcher Irrigation came out to be 46.4 per cent. With regard to knowledge of respondents, it was found that maximum gain in knowledge was for ‘working’ of rain water harvesting among both urban (93.7%) and rural (96.4%) respondents. Regarding double-walled pot, mean score on different components ranged from 3.6 – 10.9 among urban respondents and 3.0-10.7 among rural respondents after imparting training. Their knowledge level was recorded as high as 23.4 (urban respondents) and 23.3 (rural respondents) for ‘construction’ and ‘working’ of pitcher irrigation. Training changed the attitude of the respondents towards rain water harvesting technology from favourable to most favourable for majority of the urban and rural respondent. It changed from least favourable to most favourable for majority of urban and rural respondents for double-walled pot and pitcher irrigation. In totality, 81.7 per cent respondents attained high level of symbolic adoption for rain water harvesting, 66.7 per cent respondents for double-walled pot and 75.0 per cent for pitcher irrigation. Overall acceptability of the urban respondents regarding rain water harvesting was 81.6 per cent, for double-walled pot it was 88.1 per cent and for pitcher irrigation it was 64.8 per cent. Overall acceptability of the rural respondents regarding RWH was 82.1 per cent, for double-walled pot was 59.8 per cent and for pitcher irrigation was 87.1 per cent. Strategies were finally formulated on the basis of findings of the study and comprised of awareness generation by educational institutions, extension functionaries and media and action to be taken by legislative formulation.ThesisItem Open Access Risk Assessment of Workers in Polyhouses of Haryana(CCSHAU, 2014) Promila; Singh, KiranThe present study was conducted to find out the risk among workers of four different types of polyhouses (Hi-tech, NVPH, WIT and AINSH) in Haryana state. The information regarding number, area and type of polyhouses and subsidy provided by Govt. of India and Haryana on polyhouse farming was collected from respective district horticulture offices of Haryana State. Season wise climatic data (temperature, humidity, light, air contaminants, level of CO2 and solar radiation) of different polyhouses was taken to find out the difference of climatic data between polyhouses and conventional farming as well as within polyhouses. Workers form three district were examined on the basis of involvement pattern in polyhouse farming, satisfaction regarding workplace and organizational facilities and problems faced by workers at workplace. For the ergonomic study, 15 women workers of polyhouses of Karnal district were selected on the basis of good health status. Results depict that in Haryana State 614 different types of polyhouses were found under the area of 17,71,121 m2 . The total area under polyhouse farming was 0.49% of total cultivated area in Haryana State. Maximum number of polyhouses (92) and area (2,76,470m2) were found in Karnal district. Regarding environmental parameters, temperature, humidity, dust and CO2 level in polyhouses of Karnal district 19.80C, 63.9%, 255.1ppm, 6841ppm) was significantly higher (CD-0.9, 1.7, 25.9 and 33.5) than polyhouses of Ambala district (17.9 0C, 61.1 %, 222.6 ppm, 650.8 ppm) and Hisar district (17.40C, 60.18%, 221.3 ppm, 640.6ppm). Findings explain that concentration of temperature humidity and CO2 was found higher in WIT polyhouses, i.e. above 50 percent 40 percent and 50 percent, respectively in comparison to conventional farming in all month. In NVPH and WIT polyhouses climate was at extreme danger with heat score of 1820F and 2230F, which depicts that if workers continue to do work in this environment can have threat of possible heat stroke. Workers (62.79%) were involved in polyhouse type of farming from last 2-3 years and found to be working for 5-8 hrs (73.25%) daily. In polyhouse farming, workers were spending most of their days (280 days) on tying activity followed by bed making (245 days) and bed washing (242 days). Karnal workers were found to be exposed to higher temperature and humidity and were facing high problem of burn skin ( =2.04) degradation in quality of work ( =2.00), vomiting Regarding physiological parameters, in working condition heart rate of WIT polyhouse workers (103.5b.min-1) was found to be significantly higher in comparison to workers of NVPH (96.16 b.min-1), Hi-tech (92.16 b.min-1), AINSH (92.9 b.min-1) and conventional farming (87.6 b.min-1). Though blood pressure of the workers from WIT (62/98mmHg) and NVPH (61/94mmHg) polyhouses was found significantly lower in comparison to workers of other polyhouse. ( =2.00) and headache ( =2.10) in comparison to workers of Hisar and Ambala districts. Bed making and bed washing activities were done in sitting posture with flexion motion. High degree of flexion was illustrated in tying, pruning and harvesting activities with flexion of 1220, 1080 and 900, respectively. The maximum forwarded deviation (increase) in angle was observed in bed washing (202±2.6), sowing (200±2.1) and field preparation (199±1.6). On the basis of OWAS and REBA analysis the posture of workers during bed washing, tying and pruning was inappropriate with recommendation of necessary change in posture for activity. Regarding physiological parameters, in working condition heart rate of WIT polyhouse workers (103.5b.min-1) was found to be significantly higher in comparison to workers of NVPH (96.16 b.min-1), Hi-tech (92.16 b.min-1), AINSH (92.9 b.min-1) and conventional farming (87.6 b.min-1). Though blood pressure of the workers from WIT (62/98mmHg) and NVPH (61/94mmHg) polyhouses was found significantly lower in comparison to workers of other polyhouse. High concentration of temperature, humidity and carbon-dioxide were significantly affecting the heart rate, blood pressure and lung function capacity of the workers of WIT and NVOH polyhouses. Lung function capacity and heart rate of the workers from WIT polyhouse was found to be significantly (P<0.05) lower in comparison to other polyhouses with conventional farming. On the basis of study working environment of Hitech polyhouse was found significantly appropriate for workers with temperature of 170C -210C in winter and 280C-320C in summer, humidity of 63%-71% in winter and 40%- 53% in summer and CO2 of 350 ppm-523ppm in winter and 378ppm-490ppm in summer.ThesisItem Open Access Economic and Adoption Feasibility of Biomass Pellet Production Unit and Use of Pellet Stoves- A Pilot Study(CCSHAU, 2014) Sunita Kumari; Singal, SavitaThe present study was undertaken in village Kaimri of Hisar district, Haryana state. Study was conducted in four phases. Under phase-I, baseline survey on availability and use of fuels was conducted on 100 rural respondents. In phase-II, training on pellet making was imparted to ten rural women for 7 days and fifty women were trained in use of pellet stove. One pellet stove and 60- 70 kg. of pellets were distributed to selected fifty respondents for use for two months. Under phase-III, thermal efficiency of pellet stove was calculated by using the formula given by Sharma et al. (1988). In phase- IV, economic feasibility of pelletizing unit was calculated on the basis of cost-benefit ratio. Adoption feasibility of pelletizing unit and pellet stove was calculated with the help of scale given by Rogers and Shoemaker (1971). Majority of the respondents belonged to middle age (47.00%), were illiterate (43.00%) and had medium sized family. Wheat straw and cotton stalks were available in large quantities to respondents from medium and large land holding categories. Respondents used 5- 10 kg. of biomass fuel (59.00%) in traditional chulha which was collected on alternate day. Respondents faced ‘severe’ to ‘most severe’ problems in collection, fetching, storage and use of biomass fuels. Preexposure knowledge of the respondents regarding biomass pelletizing and use of pellet stove was found to be low. After imparting trainings, percentage gain in knowledge was 77.32 and 85.72 per cent for biomass pelletizing process and use of pellet stove, respectively. Thermal efficiency of pellet stove was found to be 44.93 per cent. Cost-benefit ratio of pelletizing unit was 1:2.27 which reflects it as an economically viable entrepreneurial unit. Adoption feasibility of pelletizing unit was 77.10 per cent on adoption feasibility index. Respondents used between 601-700 gm. of pellets at a time for preparing chapati/parantha, and heating of milk or water on it. Health benefits were perceived as ‘most beneficial’, followed by economical benefits and benefits related to use of pellet stove. Situational constraints like non-availability of kerosene oil and pellets ranked highest. Respondents considered pellet stove as ‘most feasible’ with 78.93 per cent on feasibility index.ThesisItem Open Access Optimization of Biomass Mixes for Harnessing Clean Fuel Energy through Pelletization: An Experimental Study(CCSHAU, 2014) Shukla, Shivangi; Singal, SavitaThe present study was conducted in two phases. Phase-I was status of biomass availability in Haryana. For this, rice, jowar, bajra, maize, cotton, sugarcane, wheat, barley, gram, and rapeseed and mustard were identified as major crops of Haryana. Findings reveled that in kharif season, rice crop generated the highest amount of biomass and in rabi season, highest amount of biomass was generated from wheat crop. Energy potential was also found highest in these two crops (rice in kharif season and wheat in rabi season). Phase-II was experimental work. In this phase, three types of biomass i.e. cotton stalk, twigs and leaves, and sawdust were used in seven different combinations for making of pellets. The prepared pellets were tested on the basis of moisture content, compression strength, calorific value, thermal efficiency, gas composition, and ash content. It was found that pellets made from different combinations were more or less similar to each other on one or more parameters. Pellets were disseminated to ten women respondents (who were similar on the basis of physical parameters) in village Kaimeri, district Hisar (Haryana) for economic and ergonomic evaluation of use of pellets. All the respondents were instructed to prepare the standardized meal (20 chapattis with 1 kg wheat flour and ½ kg potato curry) both, on traditional mud stove and pellet stove. During cooking, time, fuel, and money cost of pellets (used in pellet stove) and biomass (used in traditional mud stove) was calculated and significant saving of time, fuel and money was found during cooking on pellet stove over traditional mud stove. Environmental, physiological and biomechanical parameters were also recorded before and after 20 minutes of start of cooking, both, on traditional mud stove and pellet stove. Significant change in temperature, CO2 content, heart rate, energy expenditure, lung function and angle of deviation at both cervical and lumber region of respondents was found during cooking on traditional mud stove. Whereas, no significant change in any of the parameter except Vmax25%, Vmax50% and SVC was found during cooking on pellet stove. VAD score was also found high after 20 minutes of cooking on traditional mud stove than pellet stove.ThesisItem Open Access Economic and Adoption Feasibility of Biomass Pellet Production Unit and Use of Pellet Stoves- A Pilot Study(CCSHAU, 2014) Sunita Kumari; Singal, SavitaThe present study was undertaken in village Kaimri of Hisar district, Haryana state.

In phase-I, the baseline survey was carried out to study the existing practices of storing spices (turmeric, red chilli and coriander) and flours (semolina, gram flour and refined flour). In IInd phase, experiments were conducted to compare the different practices of storage in terms of infestation and to modify the existing low cost solar technology for safe storage of spices and flours. Under phase- I, Hisar district of Haryana state was selected purposively. Mangali and Harita villages of Hisar I block and II block were selected purposively due to easy accessibility of the respondents. A sample of 50 respondents from each village were taken, thus to make a total sample of 100 respondents. Data were collected personally with the help of well structured interview schedule. Findings revealed that majority of the respondents had farming as family occupation, very less percent were growing grams and spices on own field. Out of the respondents who powdered spices and flours at home, majority were giving sun exposure before storage while respondents who purchased spices and flours in powdered form, a small fraction exposed spices and flours before storage. Majority of the respondents used cloth for sun exposure and plastic containers for storage. In phase-II the experiments were conducted to test the efficiency of three types of storage practices viz., stored directly after purchase, stored after open exposure and stored after exposure in solar bed. The experiments were conducted for half an hour (12:00 to 12:30 pm) in open area of the laboratory of Department of Family Resource Management, College of Home Science, CCS Haryana Agricultural University, Hisar. Nine samples of ½ kg of each spice (turmeric, red chilli, coriander) and flour (semolina, gram flour and refined flour) were taken for 3 treatments. Each treatment was replicated thrice. Moisture of each sample was recorded before storage, after exposure to sun and after every month for successive 3 months. To modify the solar bed, different thicknesses of polythene was used for conducting experiments. Findings reveal that temperature in solar bed was significantly higher than open exposure and direct storage and due to the high temperature, moisture content in spices and flours was lower when exposed in solar bed in comparison to open exposure and direct storage. No infestation was found in spices and flours which were stored after exposure in solar bed. Study unveiled that temperature in case of solar bed with more gauge of polythene was raised to higher degree and insects were killed in less time in comparison to solar bed with lesser polythene gauge. This was because black sheet of solar bed is good absorber of heat.ThesisItem Open Access Management of House Dust Mites of Indoor Environment Through Selected Non Conventional Plant Products(Department of Family Resource Management, College of Home Science, Maharana Pratap University of Agriculture: Udaipur, 2010) Khatri, Kirti; Lodha, NeetaThesisItem Open Access Assessment of Manual Material Handling (MMH) Tasks in Agriculture and Designing Technology for Identified Tasks(Department of Family Resource Management, College of Home Science, Maharana Pratap University of Agriculture: Udaipur, 2010) Sinwal, Neelima; Suman Singh
