Effect of Different Chemical Nutrients (NPK) on Growth and Yield of Oyster Mushroom (Pleurotus ostreatus)
The study was conducted about the effect of different chemical nutrients (NPK) on the production and proximate composition of oyster mushroom (Pleurotus ostreatus). Mother culture of oyster mushroom was used as test crop for this experiment. The experiment consists of four different mixers of chemical nutrients viz. T1 (only 10 kg straw); T2 (2 g NPK in 10 kg straw); T3 (4 g NPK in 10 kg straw) and T4 (6 g NPK in 10 kg straw). Where NPK was kept as 2:1:1. The highest economic yield (267.38 g) was recorded in T3 treatment, again the lowest economic yield (208.11 g) was observed in T1. The highest moisture content was found in T1 (88.57%) treatment, while the lowest moisture content was recorded in T3 (84.12%). The highest biological yield (282.36 g) and economic yield (267.38 g) was attained from T3. The highest benefit cost ratio (5.17) was found from T3. Chemical nutrients (4 g NPK) with 10 kg rice straw performed significantly better on growth and yield of oyster mushroom.
