Abstract

During the 2020 and 2021 growing seasons, a field experiment was conducted at the Experimental Station, Mansoura University's Department of Agriculture, to examine the reaction of maize productivity and quality to foliar application (without foliar application, spraying with irrigation water, 200 ppm of salicylic, 5 ml/L of Agrispon and 5 ml/L of PotaMac-25) under irrigation intervals i.e. (irrigation every 14, 18 and 22 days). A strip-plot design with three replications was used to conduct the experiment. The highest values of all studied traits of maize were produced under irrigation every 14 days. Foliar spraying with 5 ml/L of PotaMac-25 in each spraying resulted in the highest values of all studied growth characters, yield and its attributes and grains quality of maize. The study's findings suggest that to achieve the highest levels of production and grain quality, it is best to irrigate maize plants every 14 days without causing them any water stress and to foliar-spray them with 5 ml/L of PotaMac-25. While, to maintain high productivity and grains quality at the same time save irrigation water, it could be suggested that irrigation maize plants every 18 days beside foliar spraying with PotaMac-25 at 5 ml/L under the local environmental circumstances of Egypt's Dakahlia Governorate's Mansoura District.
