| Abstract | ||
| A field experiment was conducted on a newly reclaimed sandy soil at the Experimental Farm of Ismaellia Agriculture Research Station during a summer season of 2009 to study the effect of applied potassium sulfate, as a mineral fertilizer, alone and its integrated with different Ksources, i.e., vinasse (by-product of sugarcane complementary industries) and wood ashes on groundnut yield and its components, i.e., chemical constituents (i.e., macro and micro nutrients uptake by both hays and seeds) and biochemical ones (i.e., seed protein, oil and its components of fatty acids). The effect of different applied K-sources on some soil properties was taken into consideration in the current study. The obtained results show that application of the tested K-sources led to a significant increase for each of the studied plant parameters (i.e., weight of 100 seed in g, weight of pods in kg fed-1, hay and seed yields in kg fed-1), chemical constituents (i.e., macro and micro nutrients uptake by both hays and seeds) and biochemical ones (i.e., seed protein, oil and its components of fatty acids). Whilst the application of the tested Ksources had a greater effect on the aforementioned plant parameters, particularly the combined treatments of potassium sulfate integrated with vinasse followed by wood ashes, which were recorded the greatest values, and potassium sulfate fertilizer alone. As for response of soil properties to the applied treatments, the obtained data reveal that the combined treatments of potassium sulfate integrated with either vinasse or wood ashes resulted in a significant decrease in each of soil pH and ECe values vs a significant increase in each of soil content of organic matter and available nutrients of N, P and K. Thus, it could be recommended that application of potassium sulfate as a mineral fertilizer integrated with either vinasse or wood ashes as combined treatments can be used for maximizing the profitability of potassium sulfate in such newly reclaimed sandy soils, and in turn increasing the yield of groundnut seeds and improving its quality. | ||
