Competitiveness of rice cultivars under stale seedbed in dry direct-seeded rice
2013
Singh, M.K.
A field experiment was conducted to study the performance of cultivar and weed management practices under stale seed bed in dry direct seeded rice. The treatment consisted of combination of two methodsof rice sowing i.e. dry seeding after stale seed bed by glyphosate 1 kg/ha and shallow tillage and two weed management treatment (weedy and two hand weeding) in main plot and four cultivars viz. ‘BPT-5204, Sarjoo -52, PRH-10’ and ‘HUBR2–1’ in sub-plot replicated thrice in split plot design. The results revealed that ‘Sarjoo-52’ was found to be more competitive than other cultivars in terms of grain yield and economics. Studies on competitive traits revealed that number of grains/panicle had highest direct positive effect whereas number of panicles/m² via number of grains/panicle had more indirect effect on grain yield.
