Effect of Potassium Humate and Boron Fertilization Levels on Yield and Quality of Sugar Beet in Sandy Soil

Abstract

To study the effect of different levels of potassium humate and boron fertilization, two field trials were carried out in a private farm at El-Nubaria region, (latitude of 30.86° N, longitude of 31.16° E and altitude of 21 m above sea level) El-Bahira Governorate, Egypt in 2018/2019 and 2019/2020 seasons. This work included sixteen treatments, represent the combinations of four levels of potassium humate as a soil application (0, 2.5, 5 and 7.5 kg/fed) and four levels of boron (zero, 70, 140 and 210 ppm/fed) as a foliar application in the form of boric acid 17% boron), which sprayed thrice at 50, 65 and 80 days from sowing and their effect on growth, yield and quality of sugar beet (Beta vulgaris var. saccharifera, L.). A split-plot design in three replications was done.
