Abstract
To evaluate the application for some type of soil amendments and micronutrient, an experiment was conducted on sandy soil at El-Ismailia, Agricultural Research Center. Such soil amendments were gypsum and bentonite as natural and compost and FYM as organic ones. Both soil amendments were applied with micronutrients as zinc and boron as foliar application. The used crop was peanut as a summer crop. This was performed through evaluating behavior of growth, nutritional status, yield and yield quality of studied crop. Management of crop for water use efficiency was also evaluating. To complete the picture the some soil properties and water characteristics has been performed taking into consideration. Data revealed clear different between both studied natural and organic soil amendments; the latter seemed to be frequently better in all parameters under study, regardless of the studied growth for peanut plants. Results showed that application both compost and bentonite as natural soil amendment was generally suitable for growth, yield and uptake of N, P and K and micronutrients Fe, Mn, Zn and B by peanut plants. This was reflected on the nutrition status of obtained seeds regardless of the applied micronutrients boron+zinc. Data also indicated that content of both protein and seeds oil, as parameters of peanut seeds quality, has been, again, most affected by compost and bentonite. Interaction analyses for the obtained data showed that the compost and bentonite accompanied with micronutrients zinc+boron seemed to be superior with all plant parameters under studied. Efficiency of water used, behaved almost similar to what previously obtained for other studied parameters, compost being the superior. To complete the picture, applied organic soil conditioners as individual treatments play a dual positive role, i.e., reducing soil bulk density vs increasing total soil porosity and pronounced decrease in hydraulic conductivity. The relatively coarse sizes of soil aggregates showed pronounced increases with all soil amendments application used. Nutrients content (macro and micro) in soil concerning to natural and organic soil amendments particularly organic were frequently more obvious compared to natural ones at all studied parameters.
