Abstract:
Effect of two organic growth supplements, Wheat bran and Molasses individually and in combinations on growth behavior and yield potential of two different species of oyster mushroom viz., Pleurotus florida and Pleurotus sajor-caju revealed that the treatment T14 (Wheat bran 800 g + Molasses 400 ml) consider best in terms of minimum mycelium growth, spawn running, pin head formation and harvesting days among all the treatments. In case of P. sajar caju 2.33 days while, in P. florida 2.67 days required for mycelium growth initiation, 13 and 14 days for spawn running period, 18 and 20 days for pin head formation respectively. The harvesting of first flush of P. florida required less average number of days 21.67 than 22 days of P. sajor-caju. The maximum production of P. florida obtained from T14 treatment (molasses 400 ml + wheat bran 800 g) as 590 g, 430 g, 292 g and 182 g at 1st, 2nd, 3rd and 4th flushes of harvesting respectively with total production was 1494 g which is 53.54% increase over control while, in P. sajor-caju maximum production was obtained as 623 g, 455 g, 280 g and 135 g respectively, at 1st, 2nd, 3rd and 4th flushes of harvesting respectively, total production was 1493 g which is 42.05% increase over control.
