The research included studying the effect of foliar spray of organic and inorganic fertilizers on plant height, number of leaves, Broccoli head diameter and weight, lateral heads number and their weight, yield (Kg.m-2), Total Soluble Solids (TSS) and vitamin C content.

The results showed that all foliar spray treatments improved the characters of Broccoli head.
