Supplementation at casing to improve yield and quality of white button mushroom

摘要

Supplementation of substrate at casing to increase the yield and quality of mushroom [Agaricus bisporus (Lange) Sing] is an important practice in commercial production of white button mushroom. This project was done to study the effects of supplementing the compost at casing with ground corn and soybean seed applied at: 0 gas control, 17, 34 and51 gper17 kgcompost on production and harvest quality of A. bisporus. There were significant differences between supplemented and non-supplemented substrates. The34 gsoybean and51 gcorn treatments had the highest yield. There were significant differences in quality indices of mushroom due to the type and amount of the supplement. The51 gsoybean supplement produced higher protein compared with other substrates. The highest vitamin C, total phenol, total soluble solids and antioxidant capacity obtained of 34 and51 gsoybeans or 34 and51 gcorn, respectively. Increased production and quality of A. bisporus may be achieved by addition of suitable amounts of supplements.
