Growth and yield of maize alley cropped with Leucaena leucocephala and Faidherbia albida in Morogoro, Tanzania

摘要: This study examined the effect of alley cropping Leucaena leucocephala and Faidherbia albida on wood biomass, maize grain yield soil nitrogen status. The treatments were: trees planted alone at 1 × 5 m spacing; intercropped with a sole crop. Mulch biomass averaged 6.18 0.97 t ha−1 for L. F. albida, respectively. Corresponding production was 1.71 1.11 ha−1. Both total N inorganic (NO 3 − –N plus 4 + –N) were higher under lowest leucocephala. Similarly, foliar concentration in plots least intercropping. Maize little affected by tree intercrop as competition resources reduced through periodic pruning clean weeding. There no gain due to presence albida. These results suggest that Gario is justified but not increasing yield.
