Summary
Pleurotus ostreatus (444) and P. sajorcaju (537) were grown on a pasteurized mixture of chopped wheat straw (70%) and milled corncobs (30%) nonsupplemented and supplemented with two levels of delayed-release nutrient. Yields for both lines increased 2.3 and 3.2 fold on substrate containing 16% and 32% (dry weight basis) delayed-release nutrient additions, respectively. For mushroom size, a differential response was observed for genotype and delayed-release nutrient. Line 444, a wild isolate from Missouri, produced larger mushrooms on substrate containing higher levels of delayed-release nutrient. Line 537, a commercial isolate used in Italy, produced smaller mushrooms with higher levels of nutrient. Mushrooms of line 537 were harvested 3 to 4 days earlier and line 444 was harvested 12 to 14 days earlier from supplemented substrate.
