EFFECT OF DIFFERENT COMBINATIONS OF GROUND FERTILIZATION AND OPTIMUS PLUS NANO-FOLIAR ON SOME YIELD TRAITS AND OIL PERCENTAGE OF YELLOW CORN

Abstract

A study was conducted in the experimental fields of Ibn Al-Bitar preparatory School in the north of Karbala for the spring season, with the aim of knowing the influence of spraying various concentrations of Optimus Plus nano-foliar and combinations of ground fertilization on the yield of the corn plant. The Randomized Complete Block Design (RCBD) was used with three replications, a factorial experiment, and two factors, the first (100% full mineral fertilizer recommendation). A mineral fertilizer recommendation of 50% with an organic recommendation of 50%, a recommendation of a mineral fertilizer of 50% with a recommendation of a micronutrients fertilizer 50%, a recommendation of a mineral fertilizer of 50%, an organic fertilizer of 25% and micronutrients 25%).The second factor included different concentrations of Optimus Plus, which are (0, 3, and 6 ml.L^-1). The results showed that Optimus Plus nano-foliar treatment  the concentration (3 ml L^-1) and the fertilizer combination (recommended mineral fertilizer 50%, organic 25% and microelements 25%)was significantly excelled by recording it the highest averages for the traits of the rows number per cob, the biological yield, the yield of one plant, the percentage of oil and The grains number per row
