Effect of crop establishment methods, nutrient levels and weed management on yield attributing characters of hybrid rice
Author(s): Abhinandan Singh and IB Pandey
Abstract: A field experiment was carried out during two consecutive kharif seasons of 2017 and 2018 at research farm of TCA, Dholi, Muzzafarpur of Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar to study the effect crop establishment methods (puddled transplanting, unpuddled transplanting and dry direct seeded rice) nutrient levels (75% RDF, 100% RDF and 125% RDF) and weed management practices (weedy check, hand weeding twice, bispyribac sodium + pyrozosulfuron and brown manuring) on yield attributes of hybrid rice. Amongst crop establishment methods, puddled transplanting produced maximum number of panicles/m2 (364.37 and 376.06), length of panicles (27.21 and 27.73), number of grains/panicles (237.31 and 243.35), number of filled grains/panicles (229.56 and 236.66) and test weight (24.18 and 24.33) which was found significantly superior over other method of sowing. 125% RDF recorded highest yield attributes viz. number of panicles/m2 (359.92 and 370.57), length of panicles (27.64 and 28.15), number of grains/panicles (229.54 and 239.49), number of filled grains/panicles (220.77 and 230.72) and test weight (24.22 and 24.32) but was found at par with 100% RDF and the both significantly surpassed over 75% RDF during both years. Among weed management practices, maximum number of panicles/m2, length of panicles, number of grains/panicles, number of filled grains/panicles and test weight was recorded under hand weeding twice but was showed similar to combined application of bispyribac-sodium + pyrazosulfuron and both had significantly higher than the application of brown manuring. The minimum yield attributing characters was recorded under weedy check which was significantly lower than weed management practices.
