The effect of nutrient supplements on the yield of Pleurotus ostreatus mushroom grown on composted sawdust of Triplochiton scleroxylon

Abstract

Cocoa nib dust, groundnut testa and dry leaves of Leuceana leucocephala significantly increased the yield of the mushroom. The best supplement was groundnut testa, which increased the yield by 57%. Yields were however reduced by the inorganic supplements used: Epsom salt, urea and NPH fertilizer (23:15:5). Epsom salt increased the pileus diameter and weight at 0.2% but the other supplements did not affect the morphology
