Abstract
In order to study the response of growth, yield, Productivity and storability of onion (Allium cepa L.)to foliar spray with some growth stimulants (seaweed-extract, chitosan,amino acids, carboxylic acids, potassium and silicon); a randomized complete block experiment was conducted with three replications. Data were collected on some growth, yield and physical characteristics, chemical components of leaves and bulbs and storability. The results indicated in some characters, that there were significant differences between most treatments with control. However seaweed treatment was the most effective treatments for plant height, total yield and marketable yield, while chitosan treatment gave the lowest values for weight loss % and the most effective treatments for P % in leaves. Also amino acids treatment was the most effective treatments for leaf diameter, leaf fresh weight, TSS % and N % in leaves and bulbs, while carboxylic acid treatment was the most effective treatments for leaf length, bulb dry weight and carbohydrates % in leaves and bulbs. Also, potassium treatment was the most effective treatment for bulb diameter and K % in leaves and bulbs, but silicon treatment gave the lowest values for rotting infection % and the most effective treatment for bulb fresh weight, single bulb % and Si % in leaves and bulbs
