Productivity enhancement of blackgram (Vigna mungo l.) through improved production technologies at farmers’ field in tribal belt of Rajasthan

Blackgram (Vigna mungo L.) is an important pulse crop in Rajasthan. One of the major constraints of its low productivity is non-adoption of improved technologies. Front line demonstrations were conducted at 200 farmers’ fields, to demonstrate production potential and economic benefits of improved technologies comprising yellow vein mosaic resistant varieties (PU-31, PU-1, Azad Urd3), line sowing (30x10 cm), integrated nutrient management (20: 40: 20, NPK kg/ha + Rhizobium + PSB@20 g/kg seed) and weed removal (at 25 days after sowing) at Banswara district of Rajasthan which comes under southern sub-humid plain zone IV B during kharif seasons 2013 to 2016 in rainfed conditions. The improved technologies recorded a mean yield of 6.15 q ha-1 which was 102 per cent higher than that obtained with farmer's practice yield of 3.08 q ha-1. The improved technologies resulted higher mean net income of Rs. 15116 per ha with a benefit cost ratio of 2.03 as compared to local practice (Rs. 1625 per ha and 1.10)
