Abstract

This study investigates the impact of foliar application of potassium nitrates of 10 and 15 mM and calboro (calcium and boron) 0.5 and 1 mg/l on the productivity and storability of summer squash Self-life also stage at 10 °C under conditions of the Aswan governorate and newly reclaimed lands during the years 2022–2023. The experiment was conducted at the Faculty of Agriculture and Natural Resources' experimental farm at Aswan uuniversity in Egypt. Three replications of a randomized complete block design were used to carry out the experiment. The highest rate of KNO₃, calboro was sprayed at a rate of 1 mg/l, and when potassium nitrate and calboro interacted, two study seasons showed superiority in the growth attributes and quality of edible crops. 15 mM potassium nitrate + 1 mg/l calboro was the treatment that resulted in the highest amounts of ascorbic acid and TSS, the least amount of weight loss, and the best pH values for fruits in the two seasons throughout the storage phase.
