In-situ Water Conservation technology for upland paddy fields in northwest Himalayan region of India.
It includes construction of small size trenches in the terraces constructed across the slope in hilly region ,it is recommended that the trench area should not be more than 12-17% of the terrace area cultivated in the paddy. The trenches having the capacity ranging from 9.9-23.1 m3 were tested in the terraces where upland paddy was cultivated and found that the trenches having 12-17% of the terrace area performed better having average soil moisture with higher yields varying from 58.4-63.6 % .The economic analysis indicated that the technology was beneficial with DC ratio of 2.14 with net present value of Rs 1.63 Lakhs with the payback period less than 2years.
