Abstract: The regular recycling of organic wastes in the soil is the most efficient method of maintaining optimum levels of soil organic matter. Recycling of organic matter in the soil should become a regular feature of modern agriculture. So, the main purpose is to evaluate the suitability of compost from different organic sources such as filter mud, spent mushroom and vermicompost mixed with sand (1:2 v/v) as growing media for
promoting growth of one-year-old of date palm (Phoenix dactylifera L.) cv. Sakkoty plantlets produced from tissue culture during acclimatization stage, control treatment were received 1g/L NPK (19:19:19). Thereby, the experiment was carried out under the greenhouse condition at the Central Lab. of Date palm Res. & Develop. Hort. Res. Inst., Giza, Egypt during two successive seasons of 2016 and 2017 seasons. The results indicated that all treatments significantly increased plant height, number of leaves/ plantlet and trunk diameter. Moreover, the content of indoles, chlorophylls pigments, N, P and K in the leaves and total count of benefit microorganisms were enhanced with the superiority of mixture filter mud compost plus sand (1:2 v/v), which gave the utmost high means over all the other mixture in both seasons. A similar trend was also gained
concerning the content of indoles and chlorophyll a, b and carotenoids in the leaves. However, the highest percent of N and K was recorded by the mixture treatment of spent mushroom plus sand (1:2 v/v) in the first season. So, it could be recommended to use filter mud compost as growing media and organic sources of nutrients to achieve consistent increase optimum levels of soil organic matte subsequent promoting growth, of date palm cv. Sakkoty plantlets produced from tissue culture during acclimatization stage.
