ABSTRACT
A field experiment was undertaken during spring-2014 at the Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar to study the effect of integrated weed management practices on weed and crop performances. The experiment was laid out in a randomized block design, consisting ten treatments. The soil of experimental site was sandy loam in texture with alkaline pH (8.2), medium in organic carbon content (4.5 g/kg) and available N, P and K. The results reveal that the weed free treatment (T9) lowered the weed population (by 118.30%), weed dry biomass (109.40%) and weed control efficiency (78.06%) compared to unweeded control which will reflected to significant increment in seed and stalk yield (98.00% and 54.80%) as well as economics of crop. Due to the highest yield in treatment T9, it was also recorded the highest uptake of N, P and K nutrients i.e., 53.37, 22.24 and 61.17 kg/ha, respectively. In contrast the nutrient uptake by weeds was recorded the lowest in this treatment (T9) due to lower weed biomass. So, efficient ecological acceptable integrated weed management practices are essential to achieve a maximum while reducing the weed population.
