White button mushroom (Agaricus bisporus) is cultivated on a well decomposed substrate, and the left over substrate after crop harvest known as ‘spent mushroom substrate or compost’ (SMS) is not finding many uses. The present study proves that the use of SMS in partial replacement of wheat straw in compost making for A. bisporus cultivation gives higher compost output/unit wt. of wheat straw with superior nutritional profile and higher fruit body yield along with superior nutritional composition. The button mushroom compost was prepared by using fresh SMS of button mushroom in three different proportions along with wheat straw, keeping standard wheat straw based formulation as control in two phase short method of composting. The compost output/unit wt. of wheat straw was 3.54 to 4.35 folds in SMS added treatments compared to 3.04 folds in standard formulation. The composts prepared with addition of SMS were superior in total nitrogen, cellulose, lignin, potassium and phosphorus along with lower C/N ratio (17: 1) compared to control (20: 1). The SMS amended composts gave fruit body yield either higher or at par with control along with higher contents of total ash, vitamin D and minerals on dry wt. basis in harvested fruit bodies.
