Abstract

Date palm (Phoenix dactylifera L.) is an important crop in arid regions, providing significant economic and nutritional value. The yield and quality of date fruits can be influenced by various agricultural practices, including the application of plant growth regulators (PGRs). Gibberellic acid (GA3) and CPPU (N-(2-chloro-4-pyridyl)-N-phenylurea), a synthetic cytokinin, are among the growth regulators known to improve fruit size, weight, and overall quality. GA3 and CPPU, both separately and in combination with potassium citrate (45%), were applied to Ferehy date palms to assess their effects on fruit yield and quality. Bunches were sprayed with GA3 (20–80 ppm), CPPU (5–20 ppm), and potassium citrate at two stages after pollination, one and two months post-pollination. The results revealed that the combined application of GA3 and CPPU significantly increased yield, bunch weight, and fruit quality compared to untreated control palms. Specifically, treated bunches showed improvements in fruit weight, diameter, height, flesh percentage, total soluble solids, and total sugars, while seed percentage, total acidity, and crude fiber were reduced. Although both GA3 and CPPU were effective when applied separately, GA3 was more effective in improving all measured parameters. Based on these findings, applying a combination of GA3 at 80 ppm and CPPU at 20 ppm, twice after pollination, is recommended to optimize yield and fruit quality in Ferehy date palms
