Impact of Cluster Frontline Demonstration on Productivity and Profitability of Greengram in Morigaon District of Assam

Abstract

The cluster frontline demonstration on greengram were conducted by Krishi Vigyan Kendra, Morigaon during 2016-17 and 2017-18 on summer season covering 60ha land with 150 demonstrations across total 8 villages with 8 clusters of Morigaon district of Assam. The improved technologies consisted of improved high yielding variety, pre-emergence weedicides, use of biofertilizers as a seed treatment, vermicompost, neem based pesticides and yellow sticky card as insect-pest management. The result revealed that the highest grain yield was obtained in demonstrated plot with an average of 1243kg/ha compared to 725kg/ha in farmer’s practice. Higher average net return (Rs.41,530/ha)was obtained in the demonstration plots compared to farmers’ practice plot(Rs.14,705/ha).The average B:C ratio was 1.45 in demonstrated plot compared to 0.47 in farmer’s plot. The average increase in the demonstration yield over farmers’ practice was 71.67per cent and net return increase over farmers’ practice was 182 per cent. The average technology gap of 157 kg/ha whereas the average extension gap of 518 kg/ha and average technology index 11.21 percent were recorded.
