Abstract

This study assessed the effect of different nitrogen source inclusion (such as rice husk and rabbit urine) affected the growth performance and proximate compositions of Indian Oyster mushroom. 5% of rice husk and 5% of rabbit urine were added to the prepared substrate composition (sawdust and palm press fibre). The mycelium run, pilus diameter, stripe length, the average total yield, biological efficiency and the proximate composition were analyzed using standard methods. The fastest mycelium run (6.5 days) was observed in 5 % rice husk supplementation. The highest pilus diameter (41.5 cm) and the highest stipe length (18.5 cm) were observed in 5% rice husk supplementation. The highest yield (202.0 g) and biological efficiency (20.2%) were obtained in 5 % rabbit urine supplement and the lowest output (52.0 g) and biological efficiency (5.2%) were observed in 5 % rabbit urine supplementation. The highest moisture (15.61%), crude fibre (8.29%), total ash (9.99%) was observed in 5 % rice husk supplementation and the highest crude fat (3.98%), crude protein (38.15%) and energy (300.04 K/cal) were observed in 5 % rabbit urine supplementation. The result predicts the suitability of combination of palm press fibre and sawdust, supplemented with either 5% rice husk or 5% rabbit urine for commercial cultivation of good oyster mushroom.
