Abstract

A field experiment was conducted during two successive seasons of 2018 and 2019 on Washington Navel orange trees (Citrus cinensis L.) grown at a private orchard, El-Riyadh district, Kafr El-Sheikh Governorate, Egypt, to investigate the impact of foliar application of Glycine betaine and Potassium silicate on growth, leaf nutrient content, productivity and fruit quality. The study consisted of seven treatments as follow; Glycine betaine concentration (25, 50 and 75 Mm), Potassium silicate (0.1, 0.2 and 0.3%) and control treatment (untreated trees) as randomized complete block design. The results showed that foliar application of Glycine betaine at 50 Mm and Potassium silicate 0.2% induced a significant improvement of vegetative growth in terms of shoot length and thickness, leaf area, leaf nutrient and pigment contents, Also, yield, number of fruits per tree was significantly increased. Moreover, Fruit quality as weight (g), fruit volume (cm3), juice% and SSC% were significantly increased, while leaf proline content and acidity were decreased. The best treatments were potassium silicate 0.2 % and Glycine betaine at 50 Mm which showed an increase in the average yield of the two seasons than the control by 40.42% and 37.95%, respectively. The results suggested that Glycine betaine at 50 Mm or potassium silicate 0.2% have a great potential in alleviating salinity stress and enhancing vegetative growth and productivity of Navel orange trees.
