Abstract
The effect of different spawn seed on different variety show significant effect on mycelia running rate of oyster mushroom that reduced the required days to complete mycelium running in the spawn packet compared to the sawdust alone. Effect of different spawn seed on different variety found to be significant in yield contributing characters and yield of oyster mushroom with some extent. The highest biological yield, economic yield, dry yield, biological efficiency (BE) and benefit cost ratio (BCR) 264.9g, 259.3g, 25.17g, 86.90, 9.11% respectively was observed in maize based spawn seed on the Pleurotus florida variety. Effect of different spawn seed on different variety has a profound effect on chemical composition of oyster mushroom. Considering all the parameters in this experiment, maize based spawn seed on the Pleurotus florida variety is found promising for lowering the cost of production as well as increasing the yield and quality of fruiting body. Wheat based spawn seed on the Pleuorotus ostreatus variety may be the fair choice.

Highlights
Mushroom plants are classified in the group of fungi and the term mushroom is used to mean these large fleshy fungi
Effect on mycelium growth The effect of different spawn on different variety showed significant effect on mycelial running rate of oyster mushroom that reduced the required days to complete mycelium running in the spawn packet compared to the sawdust alone
Maize and wheat with Pleurotus florida variety showed the highest rate of mycelium running and lowest in chickpea with Pleurotus cystidiosus variety
Summary
Mushroom plants are classified in the group of fungi and the term mushroom is used to mean these large fleshy fungi. Mushroom cultivation fits in very well with sustainable farming and has several advantages, it uses agricultural waste products, a high production per surface area can be obtained, after picking; the spent substrate is still a good soil conditioner. Mushroom is short duration and land saving crop It grows independent of sunlight, relatively fast growing, does not require fertile soil since grown on composted or non-composted agro wastes as wheat and paddy straw, banana leaves, sugarcane bagasse and leaves, wheat etc. Our country has resources and potential for large scale production of mushroom both for consumption and export .Variety is most prominent factor for better yield. In this experiment the findings of different variety on different substrates are observed.
