Most of the rabi sorghum in the country and Karnataka is cultivated under receding soil moisture conditions, which is subjected to drought at various growth stages. In this context, the growing of drought-tolerant genotypes which are adaptable to water-limited conditions is the need of the hour. With this view, front-line demonstrations were conducted to popularise the variety (SPV 2217) in the Suntnoor village of Aland taluka, Kalaburagi District. The results of front-line demonstrations indicated a higher yield (22.75 q/ha) of SPV 2217 as compared to the local variety (19.10 q/ha) due to the maintenance of greenness at physiological maturity. Due to higher yield, higher income was obtained and that led to a higher B:C ratio (2.42) as compared to the local variety (2.06). So, this improved drought-tolerant variety of sorghum can be effectively utilized by the farmers for higher productivity as compared to the local variety.

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.

Chickpea (Cicer arietinum Linn.) is most important pulse crop in Karnataka state. The productivity of chickpea is low because of non adoption of available technologies by the farmers. Hence, Krishi Vigyan Kendra, Kalaburagi conducted 149 demonstrations at farmers’ field during the last 6 years showing improved production technology. The results revealed variation in the yield obtained probably due to variation in agro-climatic parameters under rainfed condition. The highest yield of FLDs plots of chick pea achieved by adopting improved production technology was 12.87q/ha compared to farmers’ practice (10.06 q/ha). Adoption of improved production technology increased yield by 27.80 per cent over farmers’ practices. The average technological gap, extension gap and technological index were calculated as 7.13 q/ha, 2.81 q/ha and 35.65 per cent, respectively. The economical parameters indicated that net profit of Rs. 33, 213/-ha was recorded under FLDs plot over farmer practices Rs 24, 095/-ha.
