The Effect of Bio-Fertilizer, Magnetized Water and Soil Coverage on the Ratio of NPK Elements in The Leaves, Microbial Community and Measure the Basal Phosphatase Enzyme in The Maize Soil

Abstract

A factorial experiment was carried out according to the randomized complete block design (RCBD) with the split-split-plot arrangement with three replications during the season of 2020 to study the effect of three factors are the irrigation (non- magnetized water, magnetized water), the coverage (non-coverage soil and coverage soil), Bio and chemical fertilizers on NPK elements percentage in leaves, microbial community and measure the basal phosphatase enzyme in the maize soil. The results showed the interaction between magnetized water and the soil coverage and bio-fertilizer + a half dose of phosphate fertilizer led to significantly increased in the nitrogen and phosphorus content in the leaves 1.99 % and 0.46% respectively, and in the bacteria and fungi numbers in the soil, where recorded the highest value 15.43 and 9.23 cfu g-¹ dry soil respectively after 45 days, and it gave a significant increase in the basal phosphatase enzyme, where recorded the highest value 96.62 and 103.12 IU/L after 45 and 60 days respectively.
