Background: Among the pulses grown in the kharif season, blackgram occupies 8654 ha area in the Gariyaband district. But because of improper cultivation practices, blackgram yield is quite low (430 kg/ha). Thus Cluster Frontline Demonstrations were planned and carried out to disseminate latest package of practices to the farmers inorder to boost blackgram production and productivity. Methods: 50 cluster frontline demonstrations were conducted during kharif season of 2020-21 and 2021-22 in farmer’s field at Mauhabhatta and Kamepur villages of Gariyaband district, Chhattisgarh State. The demonstrations were carried out in 20 ha area to show the higher production potentiality of the technique using improved variety Indira Urd-1. Result: The results revealed that improved seed of Indira Urd-1 treated with Rhizobium +PSB and recommended plant protection cover, recorded average yield of 6.82 q/ha as compared to 4.35 q/ha in control plot. The demonstrated technology gave higher net returns and B:C ratio of 28087 Rs/ha and 3.02 in comparison to control (16245 Rs/ha, 1.67). The average extension gap, technology gap and technology index recorded were 2.47q/ha, 5.18 q/ha and 43.16% respectively. The results indicate that adoption of improved production technologies minimized the yield gap and provided higher economic returns to the farming community.
