Effect of Cultivar and Some Growth Stimulants on Yield, Tuber Quality and Storability of Jerusalem Artichoke

Abstract

In order to study the effect of cultivars and foliar application of some growth stimulants as well as their interaction on the production, quality and storability of Jerusalem artichoke; a split plot experiment was conducted with three replicates. El-Balady and Fuseau were assigned to main plots and 7 various stimulants were assigned to sub plots. Data was collected on some vegetative, yield, tuber physical characteristics, chemical components of leaves and tubers as well as storability. The results indicated in some characters, that there are significant differences between both cultivars with the superiority of Fuseau cultivar. Either seaweed extract and yeast extract treatments were the most effective treatments for yield, tuber physical characteristics, while chitosan treatment gave the lowest values for storage losses percentage. Also the interactions between Fuseau and seaweed extract, yeast, or chitosan gave the most desirable values according to the studied character.
