In this experiment, T 3 : Mango sawdust supplemented with 30% wheat bran 2 and 1% lime performed better in respect of different growth, yield and nutrient composition and mineral content of Pleurotus sajor-caju. Therefore, T : Mango sawdust supplemented with 30% wheat bran and 1% lime can be recommended for farmer level Pleurotus sajor-caju mushroom cultivation. 2 A Thesis Submitted to the Department of Biochemistry Sher-e-Bangla Agricultural University, Dhaka In partial fulfillment of the requirements for the degree of MASTER OF SCIENCE (MS) BIOCHEMISTRY SEMESTER: July-December, 2014 Mon, 01 Dec 2014 00:00:00 GMT http://localhost:8080/handle/123456789/314 2014-12-01T00:00:00Z http://localhost:8080/handle/123456789/313 EFFECT OF CHEMICAL NUTRIENTS (NPK) ON PRODUCTION AND PROXIMATE COMPOSITION OF OYSTER MUSHROOM (Pleurotus ostreatus) SHALAHUDDIN, A. K. M. The study was conducted to the effect of different chemical nutrients : Control 2 : 2 g NPK in 10 kg straw, T : 4 g NPK in 10 kg straw and T 4 3 : 6 g NPK in 10 kg straw, in NPK mix N:P:K=2:1:1. Data on different growth, yield contributing characters, proximate composition of mushroom were recorded and statistically significant variation was observed for different treatments. The highest economic yield treatment, again the lowest economic yield 1 3 . The highest moisture content was found in T 3 1 1 3 1 3 1 3 3 1 1 performed significantly better on growth, yield, nutrient and mineral content of oyster mushroom.

Data on different growth, yield and nutrient composition and mineral content were recorded and significant variation was found for different studied parameter. Mycelium running rate in spawn packet and highest average number of primordia/packet was found to be differed due to different sawdust used. The highest average number of fruiting body per packet was obtained 10.00 with mango sawdust. The highest biological yield (97.3 g), economic yield (89.2 g), biological efficiency (55.60%), cost benefit ratio (4.89) was counted under mango sawdust with 30% wheat bran and 1% lime. Among the chemical characteristics highest content of carbohydrate (74.15%), protein (12.25%), ash (1.36%), lipid (3.23%) was found with mango sawdust treatment. Among the minerals highest amount of nitrogen (1.96%), potassium (2.65%), calcium (1.92%) was found with mango sawdust with 30% wheat bran and 1% lime treatment and the lowest amount of magnesium (0.673mg), zinc (15.15mg) was found with jackfruit sawdust with 30% wheat bran and 1% lime treatment. Therefore it can be concluded that mango sawdust with 30% wheat bran and 1% lime contributed significantly on different growth, yield and nutrient composition and mineral content of Reishi mushroom (Ganoderma lucidum) .
