THE RESEARCH ON NON-CONVENTIONAL FOLIAR FERTILIZERS WITH PROTEIN HYDROLYSATES APPLIED TO MAIZE CROP

Abstract

The use of chemical fertilizers is one of the most important causes of environmental pollution. The reduction of nutrient losses can be achieved using an alternative fertilization system, a system that includes foliar fertilization. The paper presents experiment results obtained into the greenhouse applying three new ranges ofnon-conventional foliar fertilizers. These fertilizers contain protein hydrolysates and macro-and micronutrients with the role to stimulate the plant metabolism.On chernozem soil, their application to maize (H Oriente, HS Talman) ensured important yield increases of dry matter and had a positive effect on nutrient absorption and uptake in the tested plants.
