Field experiments were conducted in New Delhi, India, during the 2004 and 2005 summer seasons, to assess the effects of irrigation regimes, planting and irrigation methods and arbuscular mycorrhizal application on the productivity, nutrient uptake, water economization and economics of summer green gram on a sandy loam soil. Two irrigation regimes (I1, 2 irrigations 1 each at pre-flowering and pod filling stages; and I2, 3 irrigations each at branching, pre-flowering and pod filling stages) were allotted in main plots and 8 combinations of planting and irrigation methods (M1, flat bed planting and irrigation; M2, ridge planting and furrow irrigation, M3, ridge planting and alternate furrow irrigation and M4, furrow planting and irrigation) and arbuscular mycorrhizae (V0, control and V1, inoculation) in subplots. Results revealed that it is advantageous to apply 3 irrigations to summer green gram at branching, pre-flowering and pod filling stages by furrow planting and irrigation method with arbuscular mycorrhizae inoculation under the agroclimatic conditions of northwestern India. The highest consumptive use of water, nutrient uptake, benefit:cost ratio and water use efficiency were recorded with furrow planting and irrigation method and arbuscular mycorrhizae combination. However, 2 irrigations recorded higher water use efficiency (43.82 kg/ha-cm) than 3 irrigations (43.03 kg/ha-cm).
