Effect of Nutrient Management and Green Manure Inter Cropping on Weed Dynamics of Direct Seeded Red Rice

Field experiments were conducted during rabi 20142015 to study the effect of green manure (Sesbania aculeate) inter cropping with three different nutrient levels in four directed seeded red rice varieties, viz., Chandikar, Nourguan, TKM 9 and TPS 1 on weed flora, total weeddensity and weed dry biomass. Among the four varieties, land race chanikar recorded the lowest grasses, sedges and broad leaf weed density. In-situ incorporation drum seeded daincha (Sesbania aculeate) at 30 DAS and application 75% RDF significantly reduced the total weed density, and total weeddry biomass. Among the differentcombinations drum seeding variety Chandikar with Sesbania aculeate at 75% recommended dose of fertilizer (50: 25: 25 kg NPK ha⁻¹) in two split application recorded the lowest total weeds density and lowest total weed dry biomass production.
