Integrated Weed Management in Grain Amaranth

Weed free treatment was recorded significantly the highest grain yield (1726 kg/ha) in comparision to rest of treatments. However, among the integrated weed management treatments, oxyflurofen @ 50 g a.i./ha (PE) and interculturing fb hand weeding at 4 WAS gave significantly higher grain yield (1534 kg/ha) as compared to other treatments. Among different treatments, weed free treatment was recorded significantly higher straw yield (5811 kg/ha) which remained at par with oxyflurofen @ 50 g a.i./ha (PE) and interculturing fb hand weeding at 4 WAS (5394 kg/ha). Weed free treatment noticed the minimum weed index and maximum weed control efficiency which was closely followed by the application of oxyflurofen @ 50 g a.i./ha (PE) and interculturing fb hand weeding at 4 WAS.The maximum net realization was obtained under weed free treatment and it was closely followed by oxyflurofen @ 50 g a.i./ha (PE) and interculturing fb hand weeding at 4 WAS. Whereas, maximum benefit cost ratio was obtained by treatment of oxyflurofen @ 50 g a.i./ha (PE) and interculturing fb hand weeding at 4 WAS which was closely followed by weed free treatment.
