Yields

Abstract: A field experiment was carried out for two summer seasons at Ismailia Agric. Res. Station to study the effect of some natural minerals combined with potassium dissolving bacteria inoculation in the presence of different nitrogen forms on chemical properties of soil, nutritional status and yield of peanut-sesame. Each experiment was designed in a split-split design with three replications. Three forms of nitrogen fertilizer were included along with two natural minerals, in a presence of potassium dissolving bacteria inoculation, as well as one mineral fertilizer as source potassium fertilizer. Furthermore, data show high significant increases in available N due to the application of ammonium nitrate in combination with feldspar, and calcium nitrate in combination with potassium sulfate in a presence of inoculation for peanut and sesame, respectively. However, application of calcium nitrate combined with potassium sulfate, and ammonium nitrate in combination with feldspar, in a presence of inoculation, led to significant increases in K available in soil for peanut and sesame, respectively. Oppositely, the pH values, different to those of EC, decreased either for inoculation or non-inoculation as compared to control. In spite of that, the values of EC and pH of soil were higher with application of either bentonite or bentonite + feldspar in a presence of all nitrogen fertilizer forms. Generally, the highest EC values in soil, after the two studied seasons were encountered with calcium nitrate fertilizer as well as bentonite mineral. Moreover, applying feldspar mineral and ammonium nitrate treatments had recorded the highest values of yield components as well as nutrient (N and K) uptake by either peanut or sesame crops, particularly in the presence of inoculation as compared to those given by other treatments.
