Abstract
Frontline demonstrations were conducted with recommended scientific package and practices at farmer’s fields in the Chhattisgarh plain agro-climatic zone of Balaghat district, Madhya Pradesh to evaluate the performance of two rice varieties viz., JR-81 and JRB-1under irrigated conditions during Kharif 2019. The data on yield and economics of demonstrated under FLD, when compared with farmer’s practices on popular rice variety MTU-1010 revealed that both the rice varieties performed superior to MTU-1010. JR-81 and JRB-1with improved production technologies showed increased mean grain yield by 17.17% over existing farmers practice with Rs. 2450 ha-1 extra expenditure on inputs. The mean extension gap (7.80 q ha-1) and mean IBCR (4.78) recorded were sufficiently high, which may motivate the farmers to adopt JR-81 and JRB-1 varieties with the improved rice production technology.
