Abstract

Mushroom production is getting more and more attention as a source of food, medicine, and means of recycling organic waste. The purpose of this paper was to report the effect of different substrates composed of waste paper, wheat bran, and pea straw (Pisum sativum) on growth and yield of oyster mushrooms (Pleurotus ostreatus). One-way analysis of variance (ANOVA) was used to analyse the quantitative data collected, and pair-wise comparisons were performed using Tukey.  T11 and T12 had the fastest mycelial run; 13 days each, whereas T15 had the slowest mycelial run, 25 days. T1 and T11 had the fastest primordial development (17 days), whereas T15 had the slowest primordial formation (30 days). T2 had the largest cap diameter (10 cm), the highest fresh weight (1614 g/500 g substrate), and the highest number of fruiting bodies (263); while, T15 had the lowest total biomass (565 g/ 500g substrate) and the fewest fruiting bodies (140). The stipe length was not affected by substrate composition. The maximum number of bunches (7–7.5) were from T4, T5, and T7, while the lowest (5.5) was from T12. T7 showed highest number of aborts, 205, while T15 had the fewest, 110. With 331.2% and 117%,, T2 and T15 exhibited the highest and lowest biological efficiency. Pea straw mixed with varied amount waste paper and wheat bran revealed the possibility of these substrates to be used for oyster mushroom higher yield and yield-related parameters.
