Impact Analysis of Krishi Vigyan Kendras on Zero Tillage Maize, a Resource Conservation Technology in Srikakulam District of Andhra Pradesh

Frontline demonstrations resulted in a yield of 80.83 q hawith 14.01 per cent increase over farmer's -1-1practice of 70.90 q hawhich was much more than the district average yield of 47.33 q haand increased net returns of Rs. 18,106 per hectare (53.16 %) over farmers practice. During the study -1-1period extension gap of 9.93 q hawas found to be more than technology gap of 6.17 q hawhich emphasized the need to educate the farmers through various means for the adoption of this resource conservation technology for improved maize production with reduced cost of cultivation. Technology index of 18.51 per cent, indices of realized potential yield of 81.49 per cent and potential farm yield of 87.71 per cent had shown the feasibility of the demonstrated technology at the farmers' fields
