Effect of Zeolite Levels and Foliar Feeding with NPK Nano Fertilizer on some Soil Chemical Properties and Grain Yield of Wheat (Triticum aestivum L.)

Abstract

Abstract This study aims to demonstrate the effect of zeolite levels and foliar feeding with NPK nano fertilizer on some soil chemical properties and grain yield of wheat (Triticum aestivum L.), a field experiment was carried out during the winter agricultural season (2020-2021) in a sandy mixture of soil at the Agricultural Research and Experiments Station of the College of Agriculture, Al-Muthanna University at Al Bandar field (which is 3 km away from the city of Samawah). The study aimed at the effect of three levels of zeolite (0, 0.5 and 1) kg m 2 by volume, symbolized by Z1, Z0 and Z2, respectively, and six levels of NPK for the addition of ground and nano, spraying on the leaves in two stages at the branching and flowering, which are (0, 0.25 from the fertilizer recommendation +800 gm ha-1 nano-NPK, 0.50 from the fertilizer recommendation +800 gm h-1 nano-NPK, 0.75 from the fertilizer recommendation +800 gm h-1 NPK Nano, Recommended Ground Fertilizer Only and Recommended Nano Fertilizer Only 1600 gm ha-1), its symbols were F4, F3, F2, F1, F0 and F5 respectively in the availability of N, P and K uptake in the plant and grain of the wheat crop, the experiment was carried out by designing split plot by Randomized Complete Block Design (R.C.B.D). Wheat seeds were sown, type (Bohooth 22) on 11/11/2020. The results of the experiment showed that the addition of zeolite led to the improvement of some chemical properties of the soil, that the level Z2 achieved a significant superiority in raising the values of the concentrations of NPK elements available in the soil at the flowering and harvest stages, the compound NPK nano fertilizer had a significant effect on the chemical properties, as the levels F4 and F5 achieved the highest averages in the concentration of NPK available in the soil at. The two combinations (Z2F4) and (Z2F5) achieved significant superiority in the characteristics of nitrogen, phosphorous and potassium concentrations in the soil at flowering, and phosphorous and potassium in the soil at harvest.
