In search of suitable substrate for production of Macrocybe gigantea (Giant mushroom) locally available different agro-waste like wheat (Triticum aestivum) straw (WS), chickpea (Cicer arietinum) straw (CS), Lentil (Lens culinaris) straw (LS), Lawngrass (Zoysia tenuifolia) dry, WS+CS (1:1w/w), WS+LS (1:1w/w), CS+LS (1:1 w/w) and WS+CS+LS (1:1:1 w/w) were evaluated for the yield performance. The spawn run completed in 21-24 days in all the substrate while pinheads appears 14-16 days after casing of the bags. The substrate wheat straw +lentil straw (1:1 w/w) was found the best by producing maximum yield 5210g/6400g dry substrate (81.41% BE) followed by Lentil straw alone with yield of 5180g/6400g dry substrate (80.94% BE). The per cent increase in yield over check (wheat straw) was calculated and maximum 92.96% yield was increase in case of wheat straw + lentil straw and 91.85% in lentil straw alone. The average weight per fruit body was recorded maximum 61.11g in case of lawngrass.
