Abstract:
Field experiments was conducted to evaluate the performance of integrated weed management practices in growth, yield, nutrient uptake and economics on transplanted rice (Oryza sativa L.) during Navarai and Kuruvai season 2014 at the Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University and at farmer’s field Peruvarapur Village, Virudhachalam Taluk, Cuddalore District. The experiments consisted of fifteen treatments adopting in randomized block design and replicated thrice. The results revealed that early post emergence of Bispyribac sodium 100g/LSC 20g a.i. ha-1 on 20 DAT followed by two row finger type rotary weeder at 40 DAT recorded higher plant height, LAI, DMP, grain yield, straw yield and nutrient uptake by crop and lower uptake by weeds. The net return and benefit-cost ratio were also higher under the application of early post emergence of Bispyribac sodium 100g/LSC 20g a.i. ha-1 on 20 DAT followed by two row finger type rotary weeder at 40 DAT.
