Effect of Sawdust Ash on Nutrient Status, Growth and Yield of Cowpea (Vigna unguiculata L. Walp)

M.A. Awodun

Abstract:
The study investigated suitability of sawdust ash as nutrient source for cowpea. Six rates of ash: 0, 2, 4, 6, 8 and 10 t ha-1 were applied in two trials and soil and leaf nutrient composition and growth parameters were determined. Sawdust ash treatments applied to soil significantly increased soil and leaf N, P, K, Ca and Mg contents and numbers of pods, pod weight, number of branches, number of leaves and grain yield. Soil nutrient contents increased with the amount of sawdust ash up to 8 t ha-1 before it declined.
