NUTRIENT SUPPLEMENTATION OF MUSHROOM COMPOST AT CASING: VEGETABLE OILS

Abstract
Supplementation of compost at casing with various ground seeds caused greater increases in mushroom yield than their respective seed oil meals when supplemented and compared at equivalent rates of nitrogen addition.Supplementation with various refined and crude seed oils increased mushroom yield, particularly in the first break or flush of mushrooms. This constitutes evidence for a relationship between lipid metabolism and the initiation of fruiting in the cultivated mushroom, Agaricus bisporus (Lange) Sing.
