The Effects of Peat and Sand Amended Spent Mushroom Compost on Growing of Tomato

In this study, the effects of peat and sand amended spent mushroom compcst (SMC) on grov ı ing of tomato(Lycopersicon escelantum Mili. cv.H 2274.) were investigated, and 100% Peat and SMC, mixtures of SMC with 25%, 50%, 75% Peat, and 50% SMC + 25% Peat + 25% Sand and 50% Peat + 25% SMC + 25% Sand were used as growing media. Plant growing in SMC mixing with peat and sand was compared with 100 % Peat as control. 25% P + 75% SMC was ascertained the most appropriate mixture for plant growing in SMC mixtures. Shoot and root dry weights of control was found higher than other treatments. There was no statistical difference among 100% SMC, 50% Peat + 50% SMC and 75% Peat + 25% SMC whereas sand significantly negatively affected plant growth (P< 0.01).
