Response of rice (Oryza sativa L.) hybrids on growth and yield under agro-climatic conditions of Allahabad Uttar Pradesh

Abstract

The field experiment was conducted during kharif season of 2016 at Crop Research Farm SHUATS, Allahabad. The experiment was carried out to find the performance of 22 hybrids comparing with check variety (Vikrant 44), which laid out in Randomized Block Design (RBD) & replicated thrice. The experiment finding revealed that the treatment T12 (KR15-33) significantly performed better than all other varieties viz; Plant height (112.87 cm), Dry weight (78.73 g), RGR (0.113 g g-1 day-1), Number of effective tillers per hill (11.82), Panicle length (25.93 cm), Number of filled grains plant–1 (248.89), Grain yield (5.74 t ha–1), Straw yield (11.44 t ha–1), Biological Yield (17.21t ha–1). While the same treatment T12 (KR15-33) recorded highest gross return (137600 Rs ha–1), net return (111169 Rs ha–1) and B: C ratio (4.20), however treatment T11 (KR 15-32) and T13: (KR 15-34) were statistically at par with treatment T12.
