Pruning management is a potential tool to minimize competition between trees and agricultural crop for light, nutrients, moisture and space in agroforestry system. An experiment was carried out for three years (2010-12) in the Department of Forestry, JNKVV, Jabalpur under the All India Coordinated Research Project (AICRP) on Agroforestry. The experiment consisted of four pruning treatments (viz 0, 25, 50 and 75 % pruning) and one open in main plot and three late sown wheat varities (viz. MP 3020, GW273 and GW366) in sub-plots. The experiment was laid out in split plot design with four replications. Data of three years revealed that significantly higher grain yield (26.99 q ha-1) was recorded in open condition, followed by 75 % pruning (23.59 q ha-1), 50 % pruning (21.09 q h-1) and 25 % pruning (19.35 q ha-1). No pruning recorded significantly lowest yield (15.16 q ha-1). Wheat variety GW 273 recorded the highest grain yield (23.65 q ha-1). Mean data of 3 years showed that D. sissoo in 25 % pruning gave more tree height (11.1 m), dbh (23.1 cm), cylindrical volume (187.3 m3 ha-1) and stand biomass (451.3 q ha-1) as compared to those with 50 % and 75 % pruning. Wheat + D. sissoo in 25 % pruning gave the highest monetary returns (Rs. 40018 ha-1) at par with 50 % pruning (Rs. 35237 ha-1) but significantly superior to 75 % pruning (Rs. 32957 q ha-1), no pruning (Rs. 29112 q ha-1), crop alone (Rs. 26882 q ha-1) and tree alone (Rs. 26787 q ha-1). Among wheat varieties, GW 273 gave the highest monetary return (Rs. 35123 q ha-1) as compared to other varieties.
