ENHANCING PRODUCTIVITY OF IRRIGATED DIRECT SEEDED RICEIN STABLE SEED BED AND WEED MANAGEMENT PRACTICESS. Krishnaprabu
A field experiment was conducted at Experimental Farm, Annamalai University, Annamalainagar during2016 to study the effect of methods of rice establishment and weed management practices in irrigated directseeded rice. Treatment comprised of three crop establishment methods, viz. dry seeding after land preparationusing stale seed bed method by shallow ploughing or by glyphosate 1 kg/ha, puddled wet seeded in mainplot and five weed control measures in subplot, viz. weedy, hand weeding at 15 and 30 DAS, Pendimethalin 1 kg/ha pre emergence followed by 2,4-D EE 500 g/ha at 30 DAS, butachlor 1 kg/ha pre-emergence followedby 2,4-D 500 g/ha, fenoxaprop-p-ethyl with safener 56 g/ha 15 DAS followed by ethoxysulfuron 18 g/ha at20 DAS in a split plot design replicated thrice. Crop establishment methods did not influence rice growthand yield components and yield. Irrespective of method of establishment, hand weeding twice was foundto be superior in managing weeds in DSR than all sequentially applied herbicide treatments.
