Abstract:
An experiment was conducted to find out “Weed flora influenced by integrated weed management in grain amaranth (Amaranthus hypochondriacus L.)” at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during rabi season of 2020-21. The treatments comprised of ten methods of weed management viz., Pendimethalin @ 400 g a.i./ha (PE), Pendimethalin @ 400 g a.i./ha (PE) and inter culturing fb hand weeding at 4 WAS, T₃- Oxadiargyl @ 50 g a.i./ha (PE), Oxadiargyl @ 50 g a.i./ha (PE) and inter culturing fb hand weeding at 4 WAS, Oxadiargyl @ 50 g a.i./ha (PoE) at 3 WAS, Oxyflurofen @ 50 g a.i./ha (PE), Oxyflurofen @ 50 g a.i./ha (PE) and inter culturing fb hand weeding at 4 WAS, Inter culturing fb hand weeding at 3 WAS, Weed free, Weedy check were evaluated in randomized block design with replicating thrice. Significantly lower population of weed as well as dry weight of weed were registered in weed free treatment which was closely followed by Oxyflurofen @ 50 g a.i./ha (PE) and interculturing fb hand weeding at 4 WAS. The maximum number of weed and dry weight of total weed were recorded under the treatment of weedy check at harvest. Weed free treatment noticed the minimum weed index and maximum weed control efficiency which was closely followed by the application ofOxyflurofen @ 50 g a.i./ha (PE) and interculturing fb hand weeding at 4 WAS.
