Abstract
Addition of nutritional supplements is an effective way to enhance the yield and quality of mushrooms.
This study investigated use of different supplements such as rice bran (10%), bengal gram powder
(10%), urea (2%), ammonium sulphate (2%), poultry manure (10%), and spent mushroom compost
(10%) in rubber sawdust substrate for the cultivation of Jew’s ear mushroom (Auricularia auricularjudae)
and their effect on the nutritional composition of the mushroom. Cultivation was done in
polybags and harvested fruiting bodies were subjected to various chemical analyses using standard
techniques. The results of the study revealed that there was a significant variation in the nutrient
composition of A. auricula-judae cultivated on supplemented substrate. Rice bran supplementation
enhanced carbohydrate and ash content, while urea treatment led to an increase in protein content,
poultry manure supplementation enhanced mineral content of the mushrooms and spent mushroom
compost treatment increased crude fibre content.
