    Development and testing of low cost solar box for drying of vegetables
    (CCSHAU, 2011) Gautam, Anita; Singal, Savita
    The study was conducted in two parts viz. preliminary survey and experimental work. Survey was carried out in 2 villages of Hisar district to study the existing practices of drying of vegetables with a sample of 100 women respondents (50 from each village) who were drying vegetables at home. In part-II, experiments were conducted to develop a low cost solar box, solar drying of vegetables, and testing the cooking quality of dried vegetables. Majority of the respondents were drying fenugreek leaves, kachar, and chillies. Some respondents also dried bitter gourd, round gourd, cluster beans, cauliflower, green peas and in the quantity of 4-6 kgs for about 6 months. Experiments were conducted in the open area of department of Family Resource Management CCSHAU, Hisar under three phases. In phase-I low cost solar box (measurements: length-1.2 m, width-0.6 m, height of front wall-0.2 m, height of back wall-0.6 m) were developed with the help of College of Agricultural Engineering.. All sides of box and lid were covered with white polythene sheet and base was covered with black polythene sheet. Holes (1cm diameter) was made in the front wall and at the back wall of the box for the inlet and outlet of air. In phase-II, eight vegetables were selected viz. green peas, carrot, fenugreek leaves, cluster beans, round gourd, cauliflower, bitter gourd, and french beans for drying in open sun and in solar box. Initial moisture content of these vegetables was recorded with the help of oven on wet basis. Drying of selected vegetables was conducted from 10.00 am to 4.00 pm under open sun (Sample A) and inside solar box (Sample B) Temperature inside solar box was higher than ambient temperature. Therefore, box drying rate of vegetables inside solar box was faster than open sun drying. Solar box dried vegetables regained more moisture than open sun dried vegetables when soaked in water. In phase-III, cooking quality of dried vegetables was evaluated on the basis of organoleptic test (using 9 point hedonic scale) through 10 judges. Results showed that overall acceptability of solar box dried cooked vegetables in terms of color, appearance, aroma, texture and taste almost all were significantly better than cooking quality of open sun dried vegetables.

    Management Of household waste In urban areas In Hisar district
    (2011) Hemlata; Sangwan, Veena
    The present investigation aims at studying the existing garbage disposal practices and selecting the efficient and easy disposal method to be introduced at household level and studying its acceptability. Knowledge level of the respondents about various aspects related to garbage and its problems was tested before and after the mass media exposure. Existing method of waste generation and disposal was studied on a sample of 100 respondents in two localities of Hisar district.. Experiment work was conducted in Dept of Family Resource Management, COHS, CCSHAU, Hisar. Effectiveness of the compost prepared was tested on the basis of C/N ratio. Regarding generation of waste, varying nature of waste including organic and inorganic was coming out of every household and maximum share was of organic waste (91.19%). Out of 8.81 per cent of inorganic waste, paper was generated in large quantity (3.75%) followed by clothes (1.94%). Majority of the respondents were not satisfied with the existing garbage disposal practices outside the home (64.0%). Compost prepared with earthworms was found best as it had narrowed C/N ratio. After mass media exposure, maximum gain in knowledge was found on various aspects of waste and its problems. Gain in knowledge was highest for ‘Effect of garbage on health and environment’ (43.34%) followed by ‘vermicomposting of organic waste’ (40.21 %) and segregation of garbage (37.11). Regarding various aspects of acceptability of the appropriate disposal method it was found that the respondents were willing to do segregation of garbage and found segregation as easy to do. Regarding vermicomposting technique most of the respondents liked vermicomposting and reported it as a good method of converting household waste into rich manure. However, did not agree to adopt this method at household level but agreed to segregate the garbage if composting is done at community level. At household level organic waste is being generated as a huge amount, 91.19 per cent of the total waste. If this organic waste can be disposed off at close vicinity by vermicomposting, a major problem can be tackled down along with saving the environment.
