Effects of The Different Foliar Fertilizer Applications On The Cauliflower (Brassica Oleracea L.) Growth

Abstract

It is important to determine the requirement and application times as well as the form of the fertilizers in the foliar application of micronutrients. Objective of this study was to investigate the possible effects of commercial foliar fertilizers containing equal concentrations of Fe, Mn, Cu, Zn with chelated and non-chelate on some fertility properties of the cauliflower plant. Four different foliar fertilizers including two inorganics (non-chelated) and two organics (chelated) were selected. Results indicated that all of foliar fertilizer applications affected positively compared to control. It was observed that different chelating agents affected differently. Commercially named Fert-iz Combi, chelated with Phenolic acid/Lignin Polycarboxylate, gave the best results in terms of the amount of micronutrients in all plants. In terms of dry weight, the best result was obtained from commercially named Macro Combi, non-chelated, application. It can be concluded that the effectiveness of chelated or non-chelated foliar micronutrients depends on the severity of the deficit micronutrients on the cauliflower plants.
