Abstract

An On-farm trial (OFT) was conducted for evaluating the performance of different management practices for control of leaf curl disease of chilli in Kharif season in Chatra district of Jharkhand in two consecutive Kharif seasons of the year 2016-17 and 2017-18. The experiment was conducted in Amgawa village of Simariya block in Chatra district, where farmers generally grow Chili as a cash crop in medium land. Trial was designed in randomized block design consisting of 25 replication with three technological options i.e. TO-I:  Soil application of carbofuran granule @2 gm/plant before transplanting, TO-II – TO-I: Soil application of carbofuradon granule @2 gm/plant before transplanting, + Spray of Spinosad 48 EC @ 2 ml/lit of water after disease incidence twice after 15 days interval and TO-III – TO-I: Soil application of carbofuradon granule @2 gm/plant before transplanting, +Spray of Acephate 75SP @ 2 ml/lit of water after disease incidence twice after 15 days interval besides farmers practices. For evaluation of the performance, percentage infestation of leaf curl disease on plant/5 sqm and yield q/ha was considered, as for economic analysis gross income, net income and B.C. ratio was calculated and compared with all treatments. 

The result indicated that the minimum thrips population was found in technological option TO-III (3.35) followed by TO-II (6.45) and TO-I (6.40) respectively with a higher yield (84.5q/ha). Gross income, Net income and BC ratio was also found more in technological option TO-III. So that technology option TO-III i.e. –soil application of carbofuradone granule @ 2gram/plant before transplanting spray of acephate 75SP @ 2ml/lit of water after disease incidence twice after 15 days interval recommended considering  Bio-physical and socio-economic condition of Chatra district for control of leaf curl disease for resource-rich and resource-poor farmers. This recommendation was also given to ATMA and N.G.Os of the district for faster dissemination among the farming community.
