Abstract
xandria University in Abies, Alexandria, Egypt, during the winter and summer season of 2017, respectively. This study aimes to evaluate the effect of nitrogenrates (0, 50, 100 and 150 Kg Nfed-1) and chitosan (0, 1, 2 and 3 mll-1) and their interaction effects on postharvest quality of garlic plants. The results showed that the percentage of weight loss and chemical composition of garlic (T.S.S , dry matter and total carbohydrates) were significantly increased as N-level increased from 0 up to 150 Kg N fed-1 as well as chitosan concentrations was increased from 0 up to 3 ml/ l. The results indicated also that there were significant interaction effect due to nitrogen levels and chitosan concentrations on all characters. The storage durations months had significant effects on weight loss of garlic bulbs. It was observed that weight loss of garlic bulbs gradually increased with the increase of storage duration up to 4 months. All minerals (N,P,K) and Protein contents of garlic bulbs were significant increased by the application of nitrogen fertilization up to 150 Kg N fed-1as well as by spraying of chitosan up to 3mll-1. The interaction effects of nitrogen and chitosan on N and protein contents of garlic bulbs before or after storage were significant, however, there were as no significant effects on P and K contents of garlic bulbs after storage.
