Growth and yield of sorghum or cowpea in an agrisilviculture system in semiarid India

摘要: This study was conducted near Hyderabad, India during 1991–1994 to quantify the effects of shoot pruning, fertilization, and root barriers around Leucaena leucocephala trees on intercropped sorghum(Sorghum bicolor) or cowpea (Vigna unguiculata) crop production under rainfed conditions. Crop plants grown with pruned attained higher dry matter leaf area index than did those unpruned trees. Two-year mean grain yields sorghum no were76% 39% pure yield (1553 kg ha–1)for trees, respectively. Corresponding values for were 49% 26% (1075 kgha–1). Sorghum responded fertilizer application more strongly their respective crops, suggesting an increased need in this agrisilviculture system over that currently used crops. Impact small either crop. Irrespective barriers, a high response tree pruning suggested above ground competition light dominated tree/crop interactions system.
