EFFECT OF DIFFERENT SAWDUST AND EFFECT OF DIFFERENT SUBSTRATE ON THE GROWTH, YIELD AND PROXIMATE COMPOSITION OF SHIITAKE MUSHROOM (Lentinus edudes)

Abstract

Five different sawdust viz. Teak tree (Tectona grandis), Mango tree (Mangifera indica), White siris (Albizia procer), Jackfruit (Artocarpus heterophyllus), Timber tree (Anogeissus latifolia) sawdust supplemented with 12% wheat bran and 1% as basal substrate were selected for studies their performance on growth, yield and proximate composition of shiitake mushroom (Lentinus edudes). The highest mycelium growth rate (4.23 mm/day) was recorded in Le 11 with 1000g of spawn packet The highest time (114.80 days) required to completion of mycelium running was obtained from the treatment completion of strain Le 12 with 1000g spawn packet. The highest time (149.30 days) required for bump formation was obtained from the treatment combination of strain Le 11 with 1000g spawn packet. The highest time (16.50 days) required from opening to first harvest was obtained from the treatment combination of strain Le 12 with 1000g spawn packet. The highest diameter (10.38 cm) of pileus was recorded from the treatment combination of Le 8 with 1000g weight of spawn packet. The highest average number of primordial per packet was recorded from MT (66.45), The highest average length of stripe was recorded from MT (1.60). The highest average thickness of pileus was recorded from KT (0.70), The highest amount of nitrogen content was recorded in MT (6.78%). The highest amount of potassium was attained from MT (1.98%), The highest amount of iron was recorded from MT (625.23ppm). The highest amount of zinc was obtained from KT (9.67%). Therefore, it can be concluded that mango tree sawdust supplemented with 12% wheat bran can be further used as a better substrate for shiitake mushroom (Lentinus edudes) production reducing cost and increasing the yield and nutritional quality.
