Efficiency of Natural Minerals in Presence of Different Nitrogen
Forms and Potassium Dissolving Bacteria on Peanut and Sesame
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.
