Impact of Front Line Demonstration on Yield and Economics of Hybrid Rice Varieties (JRH-5 and JRH-19)

Abstract

The objective of the present investigation was to assess the performance of two hybrid rice varieties namely, JRH-5 and JRH-19 under irrigated ecosystem by conducting Frontline demonstrations (FLDs) in three consecutive kharif seasons of the year 2016, 2017, and 2018, in the farmer's fields located in the agro climatic zone of the Chhattisgarh plains. The FLDs were carried out using scientific package and practices of rice. The yield and economic data of the plots compared with the existing farmer practices and variety-MTU-1010 revealed that the FLDs with hybrid rice varieties JRH-19 and JRH-5 performed better. With the enhanced production technologies in FLDs with JRH-5 and JRH-19 and with only an additional input cost of Rs. 2742/ha, the mean grain yield increased by 28.21% over current farmer practices. The average extension gap (12.27 q/ha) and average IBCR (6.14) were high enough to encourage farmers to use the introduced rice production technology with the hybrids JRH-5 and JRH-19.
