Abstract:
The effect of various supplements at di fferent levels with sawdust showed significant effort
on mycelial running rate and reduced the required days to complete mycelium running in the
spawn packet. The supplementation of sawdust found to be significant in yield and yield
contributing characters of oyster mushroom with some extent. The highest biological yield.
economic yield, dry yield, biological efficiency (BE) and benefit cost ratio (BCR) of 270.5g,
266.5g, 26.34g, 93.29, 9.57%. respectively was observed in sawdust supplemented with
NPK mixed fertilizer (N=O.6%, P=O.3%, K=O.3%). Sawdust supplemented with different
levels has a profound effect on chemical composition of oyster mushroom. Sawdust
supplemented at different substrate found to be significant with mineral content of the
fruiting body. Considering all the parameters in five experiments, NPK mixed fertilizer
(N=O.6%, P=O.3%. K=O.3%) supplemented with sawdust is found promising for lowering
the cost of production as well as increasing the yield and quality of fruiting body. Cow dung
(11.5%) and starch (5.5%) as supplement with substrate may be the fair choice.
