ABSTRACT

The experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture & Technology,
Narendra Nagar (Kumarganj), Faizabad, U. P. There were 12 treatments in the experiment i. e. Isoproturon 1000 g/ha,
Isoproturon+2, 4-D 1000+500 g/ha, Clodinafop+metsulfuron methyl 60+4 g/ha, VESTA 400 (Clodinafop 15%+Metsulfuron
methyl 1%) RM 400 g/ha, Clodinafop+2,4-D 60+500 g/ha, Sulfosulfuron 25 g/ha, Sulfosulfuron+metsulfuron methyl
25+4 g/ha, Total (Sulfosulfuron 75%+metsulfuron methyl 5%) RM 40 g/ha, Metribuzin 175 g/ha, Atlantis (Mesosulfuron
3%+ iodosulfuron 0.6%) RM 400 g/ha, Weed free and Weedy check were tested in randomized block design. The results
revealed that VESTA 400 g/ha recorded maximum plant height, dry matter accumulation at harvest (g/plant), leaf area
index, minimum density of weeds and recorded highest number of spikes, length of spikes, test weight, grain yield, straw yield and harvest index.
Key words :Weed management, nitrogen uptake, yield, yield attributes, economics, wheat
