Abstract
A field experiment was conducted with seven rice hybrids (NPH-567, NP-549, NPH-8899, NPH-369, US-312, PAC-837 and Bio-404) and a local check (Kanaklata) to study their growth characteristics, dry matter production, partitioning ability and productivity during rabi seasons of 2012 and 2013. The variety Kanaklata showed the maximum plant height. The results revealed that among the cultivars studied, the maximum tillers (13.1/plant) were produced by US-312. Highest LAI was recorded by US-312 and maximum obtained at 60 days after transplanting (4.62), whereas SLW enhanced up to 90 days after transplanting. Hybrid US-312 produced maximum dry matter (25.10 g/plant) followed by NPH-8899 (24.12 g/plant) and these varieties had good partitioning ability of dry matter to developing grains. The yield components viz., filled grains per panicle, panicle length, number of panicles per metre square and 1000-grain weight were higher in US-312 followed by NPH-8899, as a result recorded highest yield of 7480 and 7235 kg/ha, respectively compared to check variety Kanaklata (5560 kg/ha).
