Abstract

The field demonstration on IPT for quality seed production in blackgram was conducted in 4 villages comprising of 76 locations of Nagapattinam District in Cauvery delta zone under Tamil Nadu – Irrigated Agriculture Modernization and Water Bodies Restoration and Management Project (TN-IAMP) during April 2018 – June 2018 by Tamil Nadu Rice Research Institute, Aduthurai, Thanjavur District, Tamil Nadu. The impact assessment with reference to increase in knowledge levels of farmers regarding scientific package of practices, extent of adoption of selected technology and percent adoption of production technology was carried out in all five blocks. The data on overall adoption level of black gram grower about recommended cultivation practices revealed that majority of the respondent had medium level of adoption of the cultivation practices (55.26%) while 31.58 and 13.16 % of them adopted of recommended cultivation practices in low and high level adoption respectively. The productivity achieved under demonstration over farmer’s practices created awareness and motivated the other farmers to adopt critical innovations for blackgram cultivation viz., selection of high yielding varieties, integrated nutrient management particularly post flowering nutrient management, integrated pest management and other technology of blackgram.
