Impact of front line demonstration on yield and economics of hybrid rice (Rajalaxmi)

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.
