Effect of Dalbergia sissoo tree rows on the growth and yield of cotton crop

ABSTRACT
Maximum percent reduction in yield (per acre) was observed on northern aspect (10.18%) followed by eastern (10.11%), western (9.12%) and minimum on southern aspect (4.97%). Adverse effect on yield was noticed upto 1.63 times the average height of the tree row on northern aspect; 0.67 times on southern aspect; 1.12 to 1.63 times on eastern aspect and 1.47 times on western aspect respectively.
Tree rows with close spacing produced more adverse effect than those planted at wider spacing. Adverse effect of shade caused by the tree rows can be minimized with proper spacing and pruning of trees. Yield losses can also be compensated from the sale of marketable trees.
