Abstract

A field experiment was carried out during the two consecutive winter seasons of 2018/2019 and 2019/2020 in the experimental farm of Faculty of Agriculture and Natural Resources, Aswan University, Egypt, to evaluate three garlic genotypes namely Egaseed1, Sids40 and Clone4 under foliar application of five rates of humic acid as control “distilled water”, 1000, 1500, 2000 and 2500 mg.l-1. The results showed that the highest plants came with 2000 mg.l-1 treatment of humic acid during both seasons meanwhile Sids40 gave the highest plants during both seasons. The highest mean values of cured bulbs owing to 2000 mg.l-1  treatment of humic acid in both seasons. While the least weight loss percentage due to 2500 mg.l-1 treatment of humic acid in both seasons. The highest average cured clove weight came with the treatment of 2000 mg.l-1 humic acid in both seasons and with the genotype Sids40.
