INTEGRATED WEED MANAGEMENT IN DIRECT SEEDED RICE UNDER IRRIGATED CONDITION ( TED CONDITION (Oryza sativa L.)

Abstract

A field experiment was conducted in Kharif season of 2015 at, J.N.K.V.V. College of Agriculture, Instructional
Farm, Rewa (M.P.) under All India Coordinated Rice Improvement Project to study- “Integrated Weed Management
in Direct Seeded Rice under Irrigated Condition (Oryza sativa L.)”. The treatments comprised ten weed control
methods which were laid out in randomized block design with three replications. The rice variety IR-64 was line
sown under irrigated condition keeping seed rate 50 kg/ha and distances between rows 20 cm. The crop was
grown as per recommended package of practices. The Study revealed that amongst the different weed control
treatments, the equally highest grain yield (40.39 to 40.72q/ha) were obtained under pendimethalin + bispyribac
sodium or 2,4-D (T2
and T3
) and from butachlor + bispyribac sodium (T6
) treatments. The highest weed control
efficiency (78.12%)and net income (Rs. 38612 /ha) was achieved under T6 (Butachlor @1.5kg/ha(4DAS)+
bispyribac sodium @ 35g/ha (20DAS) followed by T2(pendimethalin@1.00kg/ha(4DAS)+bispyribac sodium @
35g/ha (20DAS) 77.97% and Rs. 37.346/ha respectively
