Poor residue handling capability of no-till drills in combine harvested rice and wheat fields during sowing of wheat in rabi and pulses in kharif is a major barrier for their extensive use. The problem aggravates more due to lesser inter-spacing between furrow openers and their arrangements on only two toolbars. A study was conducted to assess the effectof furrow opener arrangements on residue accumulation on a test setup with three toolbarsand seven inverted-T type furrow openers. Six patterns of furrow opener arrangements were evaluated in combine harvested wheat field. Furrow openers in V-type arrangement of 2, 2 and 3 on front, middle and rear toolbar, respectively, (Arrangement-B) was thebest in terms of residue entanglement and accumulation of 121 g.m-1 length. No residueaccumulation was observed when the setup was operated under chopped residue conditionwith same arrangement. Residue flow percentage was 100% for this arrangement. There sult suggested arranging the furrow openers on three toolbars with wider furrow openerspacing to minimize the residue accumulation while drilling pulse crops under no-tillresidue condition after wheat harvesting.
