Home Science

Popularization of nutrition garden to improve the micro nutrients

Demonstration on nutritional garden was conducted in 5 villages with two beneficiaries in each location. Approximately 64 Kg of green leafy vegetables and 52 Kg of other vegetables worth Rs. 950/- was produced within a period of 3 months. A great change in consumption pattern was observed. Now they are taking greens twice in a week and vegetables consuming regularly. Their health status was improved.

Effect of nutrition education in rural areas

This trial was conducted at 5 different Govt. schools in Indhukurpet, Devispet, Cherlayagarithopu, Nellore Rural and Kothur villages on 356 students. Pre and Post evaluation were conducted on Nutrition Education and it was found that their knowledge and attitudes were improved 46% in nutrition and 57% in health habits.

Performance of drudgery reducing hand implements

(a) Improved hand weeders

Conducted demonstrations at selected locations. In demonstrated plot, a person did weeding operation with improved hand weeders in ground nut field of 4 cents whereas with the traditional weeders a person weeded 2.5 cents of groundnut field in 4 hours. According to the farm women, they felt less drudgery while weeding in different crops.

(b) Headload manager:

This front line demonstration was conducted at 5 different locations. By using this instrument farm women can weigh the agricultural produce with less strain on the shoulders. Still there is a need to popularize this head load manager usage among farm women.

(c) Harvesting bag:

Harvesting bag was helpful in picking more quantity of cotton (4.34kg/30min) than the picking operation without using harvesting bag(2.44Kg/30 min). By using this harvesting bag, cotton picking efficiency was improved.

Vermi compost

This trail was conducted at 3 different locations. The results showed that there was a production of 12.25 kg of earth warms and 850 kg of vermi compost in 4 months duration in an area of 112.5 cut size pit.
