Abstract

Two field experiments were conducted during 2019/2020 and 2020/2021 growing seasons at the National Research Centre Experimental farm at El-Nubaria, El-Behira Governorate. The aim of the research was to study the effect of potassium fulvate and organic nitrogen on the growth, yield and nutritional status of onion plants grown in sandy soil. The factorial experiment was consisting of 12 treatments with four replicates. The experiment was arranged in split plot design. Four levels of K-fulvat (10% K₂O) (0, 25, 50 and 75 kg/fed.) were occupied at the main plots and the three concentrations of organic nitrogen (15 % N) (0, 1, 2 cm/l) were randomly allocated in the sub plots. The results indicated to increase in spraying the concentrations of organic nitrogen from 0 to 2 cml^-1 with the addition of different rates of potassium fulvate, the growth and yield parameters of onion plants increased significantly and morally during the two successive growing seasons. The best experimental treatments were which gave the highest yield and quality of onion bulbs when spraying the highest concentration of organic nitrogen (2 cml^-1) with the highest addition of potassium fulvate (75 kg fed^-1), during the two successive growing seasons.
