Abstract:

A field experiment was conducted at Birsa Agricultural University farm (Lat:23⁰17’N, Long:83⁰19’E, Altitude:625 m above MSL) in Kharif 2012 and 2013 with 3 rice hybrids and one high yielding variety viz., DRRH-3, PAC-837,ARIZE TEJ and Lalat having four seed rate in split plot design to assess the effect of varying seed rate and cultivars under aerobic condition. Rice hybrids, PAC 837 gave significantly higher total dry matter accumulation, crop growth rate, net assimilation rate, leaf area index, effective tillers (306 m-2), grains per panicle (115), 1000-grain weight (24.30 g) resulting in higher grain (4.94 t ha-1) and straw (7.03t ha-1) yield and harvest index (41.20%) with net return (Rs. 37790 ha-1) and benefit cost ratio (1.48) than other rice cultivars. Rice hybrid PAC 837 sown with 25 kg seed per ha produced higher grain yield (5.2 t ha-1), net return (` 41710 ha-1) and benefit: cost ratio (1.70) than other combinations of hybrids or HYV and seed rate except hybrid rice PAC 837 sown with 35 kg seed ha-1. Hence, it may be concluded that cultivation of aerobic rice hybrid PAC 837 with 25kg seed per ha may be practiced in Jharkhand for higher productivity and profitability.
