ABSTRACT
Maximum percent reduction in yield (per acre) was observed on northern aspect (11.29%) followed by eastern (8.43%), western (8.22%) and minimum on southern aspect (3.40%) respectively. The reduction in yield of cotton crop grown along the east-west oriented tree rows was slightly less than when grown along the north-south oriented tree rows. Adverse effect on yield was noticed up to 1.38 times the average height of tree row on northern aspect; 0.72 times the average height of tree rows on southern aspect; 1.28 times the average height of tree row on eastern aspect and 1.22 times the average height of tree row on western aspect, respectively. Tree rows with close spacing and large crowns produced more adverse effect. Adverse effect of shade caused by tree rows can be minimized with proper spacing and proper pruning of trees. Yield losses would be compensated from the sale of trees.
