Effect of establishment techniques and weed management practices on yield attributes, yield and quality of Kharif rice (Oryza sativa L.)

A field experiment on “Effect of establishment techniques and weed management practices on yield yield and quality of kharif rice (Oryza sativa L.)” was conducted at Agronomy Farm (17.10º North latitude and 73.10º East longitude), College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.) during Kharif 2017. The field experiment was laid out in strip plot design. The main plot treatments comprised of five crop establishment techniques (T₁: Seed sowingon flat bed with drum seeder, T₂: Transplanting by hand operated transplanter, T₃: Transplanting by mechanical transplanter, T₄:Dibbling on BBF with polymulch and T₅: Recommended manual transplanting with puddling) and the sub plot treatments consisted of three weed management practices (W₁: Weedy check, W₂: Weed free check (hand weeding 20, 40 and 60 DAS/DAT) and W₃: Pre-emergence (Oxadiargyl@ 0.12 kg/ha)+ one hand weeding at 30 DAS/DAT)). There were 15 treatment combinations replicated three times.From investigation, it can be concluded that for obtaining higher grain and straw yield and quality of kharif rice, the rice crop should be established by seed sowing on flat bed by drum seeder along with pre-emergence application of oxadiargyl @ 0.12 kg/ha + one hand weeding at 30 DAS.
