Enhancing in the productivity of blackgram through chemical and bio fortification practice trials in Kalaburagi district of Karnataka

Abstract

Blackgram (Vigna mungo L.) is one of the major rainy season pulse crops also known as urd or mash grown throughout India. One of the major constraints of its low productivity is non-adoption of improved technologies. In this point of view Krishi Vigyan Kendra, Kalaburagi conducted Front line demonstration at 108farmers field to demonstrate production potential and economic benefit of improved technologies comprising improved varieties, integrated nutrient management and timely weed removal, line sowing (30 × 10 cm), and IPM. The seeds were treated with biofertilizers. Pre-emergence application of weedicide Pendimethalin at 2.5 kg a.i /ha used for effective control of the weeds during Kharif season of 2014-15 to 2016-17 in rainfed condition. The improved technology recorded a mean yield of 8.46 q/ha which was 14.18 % higher than that obtained with farmers practice yield of 7.29 q/ha. The improved technologies resulted higher mean net income of Rs.27613 /ha with a benefit cost ratio of 2.83 as compared to local practice (Rs. 22721/ha, 2.55 respectively). There is a need to adopt multipronged strategy that involves enhancing blackgram production through better adoption of improved technology.
