Description A field experiment was conducted at IARI, New Delhi during 2007 and 2008 to study the effect of planting system and phosphorus on productivity, moisture use efficiency and economics of sole and intercropped pigeonpea [Cajanuscajan (L.) Millisp.] under rainfed conditions on a sandy loam soil. There was significant superiority in growth and yieldattributes as well as yield of pigeonpea under sole pigeonpea as compared to their intercropping with mungbean. However,pigeonpea equivalent yield (1.86 tonnes/ha) was the highest under intercropped pigeonpea. Intercropping system recordedthe higher consumptive use (380.1 mm), moisture use efficiency (4.25 kg/ha-mm), moisture use rate (2.62 mm/day) as well as nutrient uptake and fetched higher net returns (Rupees 21.91 × 103/ha) and B: C ratio (2.1) over sole pigeonpea. Results showed significant improvement in yield attributes and yield under different planting systems (Broad bed and furrow (BBF) and paired row planting) over the uniform row planting. The highest value of moisture use indices (consumptive use, moisture use efficiency and moisture use rate) and economics (net returns and B: C ratios) were recorded with broadbed and furrow planting and lowest in uniform row planting. Among phosphorus levels, application of 80 kg P2O5/ha followed by 40 kg P2O5ha with biofertilizers (phosphate solubilizing bacteria and vesicular and arbuscular mycorrhizae) resulted in better performance of crops over other treatments.
