| Two field experiments were conducted at the experimental farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt, during 2021and 2022 summer seasons. The main objective of the study was to determine the effect of foliar spraying with some of fertilizers by NPK and foliar application of saucers NPK (2% Urea, 3% P2O5 and 4% K2O) during panicle initiation and mid - booting stages on rice growth, yield, yield attributes and grains quality characteristics of the rice cv. Sakha 108. The experimental design was a randomized complete block design with four replications. Foliar application treatments were ((2% Urea, 3% P2O5 and 4% K2O) under three rates from NPK 50%, 75% and 100% recommended. The plant growth, yield, yield components and grains quality characteristics were collected. The tested chemical substance significantly improved thee studied characteristics of rice grain quality, yields and yield contributes compared with the control treatment. Fertilization with 75% NBK recommended with foliar spray with a mixture of (2% Urea, 3% P2O5 and 4% K2O) at panicle initiation + mid booting stages was significantly the most efficient treatment in improving rice grain quality, growth and yields without significant difference with the mixture of NPK treatment regarding rice grain quality improvement. The mixture of 2% Urea, 3% P2O5 and 4% K2O could be recommended from NPK 50% and 75% for improving rice quality and productivity of Sakha 108 under conditions of the northern delta | ||||
