Peanut (Arachis hypogaea ) is an important grain legume and, at the same time ,it can be considered among the oil crops that is widely cultivated in sandy soils of Egypt. The current research represents a trial towards its cultivation in a calcareous salt affected soil having a clay loam texture.These conditions are thought to be not suitable for growing peanut plant. Therefore, some treatments involved spraying plants with K in either humate or silicate forms whether applied solely or combined with amino acids and/or yeasts in a field investigation which was carried out for two winter successive seasons i.e.2022 and 2023. It has been shown that such treatments could affect significantly all plant growth parameters i.e. plant height, number of branches plant-1, weight of pods plant-1 and weight of seeds plant-1. Also, the plant contents of the macro nutrients ( N,P and K), micronutrients (Fe, Mn and Zn) as well as some chemical compounds i.e.chlorophyll A, chlorophyll B and carotenoids in leaves of the peanut plant beside of its contents of protein, carbohydartes and oil in seeds responded positively and significantly to the aforementioned treatments. However, it is worthy to indicate that the effects of the silicate form surpassed that of the humate one and, at the same time, the yeasts enhanced the effect of the applied K more than the amino acids. The integration between K-silicate+amino acids+yeasts recorded the highest increases in macro and micro- nutrient concentrations in plants; hence raised significantly plant growth and productivity
