Abstract

The effect of chemical and biological oat straw supplements was evaluated in order, to increase productivity in Pleurotus ostreatus var. BGAT. The evaluated products were: extract of pinheads var. CL, extract of pinheads var. BSMA; extract of pinheads var. BGAT; agromil; copper sulfate; Trichoderma metabolites; sorghum paste; and control, each in two different doses. The experimental unit consisted on a polyethylene bag of 40x60cm, with 4.3kg of humid substrate + 200g of inoculums, which were distributed in a totally random design, with six repetitions. The evaluated variables were: days to pinhead formation, number of pinheads, number of days from pinhead formation to crop, total yield, and biological efficiency. Variance analysis and Tukey test were carried out. Sorghum paste significantly stimulated the formation of fruitful pinheads of P. ostreatus var. BGAT, with larger number of pinheads, total yield and biological efficiency, increasing production by 31.6%. Fewer days from pinhead formation to crop were achieved with the extract of var. BSMA, 61.7% faster than substrate without supplementation. Copper sulfate did not increase production, yielding less product than the control substrate without supplementation.
