Leaf ant root (tuber) nutrient uptake patterns of cassava (Manihot esculenta Grantz) alley-cropped with gliricidia (Gliricidia sepium), leucaena (Leucaena leucocephala), and senna [Senna (syn. Cassia) siamea] as influenced by vesicular-arbuscular micorrhizal (VAM) inoculation in a degraded Alfisol were investigated in 3 consecutive years. The cassava plants were mulched with fresh prunings of each hedgerow tree species at 2-month intervals in the second and third years of alley cropping. While VAM inoculation significantly influenced the root uptake of nutrients, the leaf uptake was not affected except for the uptake of P. In most cases, there was not dofference in the nutrient concentration between inoculated and uninoculated plants, either in the leaf or in the root, indicating that the productivity of cassava was regulatedbu the amount of nutrients the roots could absorb. In spite of similar total soil N in all inoculated and uninoculated alley-cropped cassavaplots and similar exchangeable soil K contents in inoculated and uninoculated alleycropped cassava plots with leucaena and senna, greater uptake of N, P, and K and grater concentrations of K were observed in roots of inoculated alley-cropped cassava with gliricidia and leucaena than with senna. |
