Abstract

The Hybrid rice Rajalaxmi recorded  higher plant height(98.1 cm), effective tillers hill-1(21.5), Length of panicle(24.1 cm),  grains panicle-1(248) and test weight(23.65 g)  than the local check(HYV Lalat). The same also recorded grain yield  63.75 q ha-1 which is 56.53 % higher yield than local check(Lalat) with harvest index of 47.2 % over the years of study .  In spite of increase in yield of  improved technology the technological gap, extension gap and technology index existed which was 6.25 q ha-1, 23.05 q ha-1 and  8.93 % respectively. The improved technology of hybrid rice gave higher gross return of Rs. 88834 ha-1 with a benefit cost ratio of 1.88 and  additional net return of Rs.25277 ha-1 as compared to local check . Hence the existing HYV Lalat can be replaced by Hybrid rice Rajalaxmi  since it fits to the existing farming situation for higher productivity and income.
