| The primary objective of this study appears to be an evaluation of irrigation water distribution equity among rice farmers and its effects on yield and water use efficiency. through studying the impact of spraying potassium silicate and compost under a water deficit on improving rice growth, productivity, and water use efficiency. A field experiment was conducted at the Experimental Farm Sakha Agriculture Research Station, Kafr El-Sheikh, Egypt, during 2022 and 2023 rice growing seasons. A strip plot design, with 3 replications. Three irrigation intervals were used the vertical plots were irrigation every 4, 8, and 12 days. The horizontal plots were made up of combined potassium silicate rates of 0, 0.5%, 1.5%, and 3% + recommended rate of compost rice straw (5t/ha). Growth characteristics, grain yield, and components, and rice grain quality traits were assessed. The present study revealed that extending the irrigation interval beyond I4 resulted in a significant decline in plant growth parameters, grain yield, and associated yield components. In addition to, the combined application of potassium silicate and compost demonstrated a promising effect, with increases observed in rice grain quality, yield, and its constituent components. The highest amount of total applied irrigation water was recorded by irrigation every four days, whereas I12 exerted the least. Amount I8 had the best water productivity. It could be concluded that prolonging irrigation from 8 to 12 days could be applied to enhance water and insignificant yield reduction under the case of 3% K2SiO3+5 t/ha compost for Sakha 106 rice cultivar | ||||
