Effect of planting methods on soil moisture regime, survival and dry weight of seedlings of different tree species.

摘要

A field experiment was conducted at Sanknal village, Bijapur district during July 2007. Soil moisture regime, survival, dry weight of seedlings and economics of different tree species were influenced by various planting methods in dry tract of northern Karnataka, Planting of tree species in crescent method recorded higher soil moisture content, dry weight and survival of seedlings (73.22 and 69.50% at 200 and 500 days after planting) followed by staggered trench method of planting. The tree species Gliricidia sepium recorded higher soil moisture content, dry weight and survival of seedlings at 200 and 500 days after planting (84.08 and 80.16%, respectively) as compared to other tree species. The staggered trench method appeared to be optimum with low cost and optimum results in terms of growth and productivity. However, none of interaction effects was found to be significant.
