The study was carried out to test the possibilities of using cassava peels, stalks singly and in combination and to determine the effect of additives on the performance of the Pleurotus pulmonariuson the substrates. The research started with different steps, media production, and development of spawn, substrate preparation, vegetative phase, mushroom fruiting and harvesting. The experiment was in five sets; One set was using cassava peels alone, cassava stalk alone, cassava and stalk combination, cassava peels and PKC, cassava stalk and PKC. The data obtained were subjected to analysis of variance (ANOVA). Test of significance were carried out using Duncan multiple range test at P0.05.The cassava stalk (80%) + cassava peels (20%) had primordial appearance in 6days, cassava stalk alone at 28days and cassava peels alone 15days. The biological efficiency of cassava peels was 8.9%, cassava stalks was 13.1% while cassava peels and cassava stalk with the addition of PKC increased the biological efficiency from 34.0% to 48%. The results of this study shows that the mushroomPleurotus pulmonariusexhibited an increase in performance with increased additive (PKC), 20% inclusion level is the most efficient.
