Abstract

Yield and yield contributing attributes of BR11 rice were influenced by different doses of the herbicides used. The highest grain yield (5.14 t ha-1), thousand grain weight, straw yield were obtained by the treatment Golteer 5G at 24.70 kg ha-1. The tallest plant and second highest grains/panicle were produced in Settoff 20WG at 50 g ha-1. Number of grains/panicle was found to be maximum in plots treated with Ronstar 25EC at 1.0 l ha-1. The smallest plant, lowest number of effective tillers plant-1, non effective tillers plant-1, grains panicle-1, thousand grains weight, grain yield and straw yield were found in control. Golteer 5G at 12.35 kg ha-1 produced the highest number of non effective tillers plant-1. The results also demonstrated significant difference among the treatments.
