Abstract
A field experiment was conducted on a sandy loam soil at Indian Agricultural Research Institute, New Delhi during rainy (kharif) season of 2003 and 2004. The treatment combinations comprised two cropping systems [pearlmillet sole (50 cm row spacing) and pearlmillet paired row (30170 cm row spacing) + one row of mothbean] and three fertility levels (control, 40 kg N + 20 kg P20gha and 80 kg N + 40 kg P20,/ha) in main plots; and four moisture-conservation practices (no mulch, dust mulch + straw mulch, kaolin + straw mulch and farmyard ma- nure (FYM) Q 5 tlha + dust mulch + straw mulch) in subplots. Split-plot design was followed with three replica- tions. The planting of one row of mothbean between paired rows of pearlmillet proved superior to sole pearlmillet in respect of pearlmillet-equivalent.yield (29.60 qlha), water use and economics. Application of 80 kg N + 40 kg P,OJha as also FYM Q 5 tlha + dust mulch + straw mulch recorded significantly higher pearlmillet- equivalent yield, nutrient uptake, water use and economics compared with the rest of the treatments.
