Effect of different herbicides on weed control in cotton and soybean intercropping system

A field experiment was conducted at Cotton Research Scheme Farm, VNMKV, Parbhani during kharif season ۲۰۱۵-۱۶ and ۲۰۱۶-۱۷ in randomized block design with seven treatments in three replicates. Sowing was done by dibbling with spacing ۱۲۰ cm x ۳۰ cm for Bt.cotton and for soybean ۶۰cm x ۵cm. The result indicated that, spraying of pre emergence application of Oxyflurofen ۲۳.۵% EC at ۰.۱ kg/ha ai followed by hand weeding and hoeing at ۶ week after sowing (WAS) recorded significantly highest seed cotton equivalent yield (۱۸۶۸ kg ha-۱), gross monetary returns (۸۱۵۹ Rs/ha) and net monetary returns (۳۹۰۲۴ Rs/ha) over rest of the treatment except it was on par with application of pre emergence application of Pendimethalin ۳۰% EC at ۰.۷۵ kg/ha ai with hand weeding and hoeing at ۶ WAS and Alachlor ۵۰ % EC at ۲.۰ kg/ha ai followed by hand weeding and hoeing at ۶ WAS. The treatment Spraying of pre emergence application of Oxyflurofen ۲۳.۵% EC at ۰.۱kg/ha ai followed by hand weeding and hoeing at ۶ WAS was found productive and profitable followed by Pendimethalin ۳۰% EC at ۰.۷۵ kg/ha ai with hand weeding and hoeing at ۶ WAS and Alachlor ۵۰ % EC at ۲.۰ kg/ha ai followed by hand weeding and hoeing at ۶ WAS.
