Abstract
The study was conducted in North-eastern part of Karnataka during 2018-19 to evaluate performance of pigeonpea (Cajanus cajan) in association with 25 years old eastwest and north-south bund planted neem (Azadirachta indica) in agroforestry system under rainfed conditions. The experiment was laid out in split plot design with three replications and 12 treatment combinations with selective randomization with one outside control. Main plot consisted of 4 directions viz., eastern, western, northern and southern directions and sub plot consisted of 3 distances viz., 0-5.4, 5.4-10.8 and 10.8-16.2 m from tree line. Neem planted in east-west direction has attained 126.5 cm girth and 12.6 m height whereas in northsouth direction it has attained girth of 131.6 cm and height of 13.2 m. Pigeonpea seed yield was higher on southern direction (587 kg ha-1) and at distance of >10.8 m (761 kg ha-1) from tree line over other directions and distances. Southern direction planting at >10.8 m distance recorded higher seed yield (778 kg ha-1) and was comparable to sole pigeonpea (780 kg h-1) compared to 0-5.4 m distance on western direction (346 kg ha-1). Lower yield under agroforestry system was attributed to reduction in growth and development of crop due to shading and leaf interference. Soil pH and EC were lower and organic carbon and available nitrogen, phosphorus and potassium were higher under agroforestry system particularly in western and northern directions in 0-5.4 m distance and these decreased with increase in distance from tree line. Further, investigation revealed that microbial population was significantly correlated with the soil organic carbon and nutrients particularly on western and northern directions.
