Greengram, Sulfosulfuron, Weed management, Wheat, Zero tillage

An experiment was conducted on zero-till (ZT) wheat grown after greengram at Jhansi during 2019-20. Broad-leaved weeds dominated (90-95%) the field, with limited occurrence of grassy weeds (5-10%). Weed density was higher under conventional tillage (CT) than ZT. Wheat grain yield was the highest under ZT, but there was no effect of greengram residue along with ZT. Pre-emergence application (PE) of pendimethalin followed by (fb) post-emergence application (PoE) of sulfosulfuron provided effective control of weeds, and improved weed control efficiency (88.2–90.5%). Herbicidal efficiency index also was maximum with pendimethalin PE fb sulfosulfuron PoE. The improved profitability with enhanced productivity of wheat can be achieved with ZT with application of glyphosate before sowing wheat after greengram and usage of sulfosulfuron PoE for controlling weeds. The greengram residues along with ZT may prove beneficial in the long-run.
