This research was conducted in the Mushroom Research Laboratory at Al-Qasasin Research Station, Ismailia Governorate. The research was conducted over two successive seasons, 2019 and 2020. This experiment aimed to study the effect of some organic additives to the rice straw environment on the physical crop and its husks. Components of the bodies of the oyster mushroom (Pleurotus Florida strain 14).These parameters were measured during the experiment of cap diameter, cap weight, fruit body weight, dry matter, early yield (gm), total yield, N.P.K. contents, carbohydrate, and protein content. The results showed significant differences in all the traits under study, and the use of rice straw + humic acid at an at 5% achieved the highest values in most of these traits. Regarding the chemical components of the fruit bodies, the use of rice straw + humic acid enhances the proportions of dry matter, phosphorous, nitrogen, protein, and total carbohydrates. Also, applied coffee residues to rice straw were recorded In general; the results indicated that using rice straw with humic acid at the rate of 15 %as growth substrate to oyster mushroom was table substrate as compared to other applications
