CULTIVATION OF REISHI MUSHROOM (GANODERMA LUCIDUM) ON DIFFERENT LOCAL SUBSTATES IN KURDISTAN REGION, IRAQ

Abstract

In this investigation, the impact of five locally sourced sawdust types and additional substances on crop yield and chemical contents of Ganoderma lucidum and three levels of spawning rates (5, 10 and 15%) were studied. The organic materials used were as follows: The sawdust of Wheat straw, Rice straw, Populus Canadensis, Salix Alba and Cardboard, some supplemented substrates compare with raw organic Substrates led to an increase in fruits bodies fresh weight by 194 G bag-1compared to the raw substrates by 180 G bag-1 and with significant differences. Otherwise the cap width also had significant differences by 6.3 cm in raw substrates while supplemented substrates were 5.5 cm, While there were some variations in other characteristics examined, such as the weight, length, and diameter of the cap and stipe, there were no noteworthy differences in the levels of protein, nitrogen, carbohydrates, and vitamin C in the mushrooms grown on different organic substrates, while there were significant differences between substrates with ash and fiber, the best substrates were Carolina poplar sawdust by 7.57% for ash and 31.26% for fibers and white willow sawdust 7.76% for ash and the lowest value for ash 6.77% for wheat straw. 30.93% for fibers with Rice straw substrate, there were clear significant differences in most of the studied traits of fungal inoculum levels, and the best level was 15%, which led to a proven increase in most traits.
