A field experiment was conducted in Balindi farm, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, West Bengal with five different wheat cultivars (viz., DBW-39, DBW-107, HD-2967, CBW-38, DBW-187) which were grown under different regimes of conservation agriculture in a split-split plot experimental design. Main plot treatments include three different regimes of tillage intensity viz. Zero-tillage (ZT), Reduced tillage (RT) and Conventional tillage (CT). Subplot treatments are combinations of five level of different nutrient residues combination. Sub-sub plot treatments are five different types of wheat cultivars. Among the tillage systems, zero tillage showed the highest yield (2,319 kg ha-1) compared to conventional tillage and no-tillage. Among the five nutrient residues combinations, 50% residue + 100% N.P.K gave significant yield and DBW-107 (2,626.19 kg ha-1) performed well compared to other varieties. It was found that, among various combinations Zero tillage system with 50% rice residues + 100% N.P.K with DBW-107 variety yield significantly compared to other combinations. Army worm (Mythimna separata) was the major problem during the wheat cultivation at its early growth stage mainly during tillering phase. It was effectively managed by the spot application of Regent (Fipronil) 5 SC @ 1 ml per liter of water.
