EFFECT OF FOLIAR FERTILIZING ON THE YIELD OF SOME ALMOND CULTIVARS GROWN IN NORTH MACEDONIA

Abstract

The aim of this study was to determine the effect of foliar fertilizing with different fertilizers on the yield of feranjez, texas and primorski almond cultivar, grown in Valandovo region, North Macedonia. The variants were: 1. Control (untreated); 2. Ever green with Me (55% organic matter, 2% w/w Mg, 2% w/w Fe, 2% w/w Zn, 2% w/w Mn, 0.5 % w/w Cu, 0.5% w/w B); 3. Biolinfa (34% organic matter 3% N, 5.80% K2O); 4. Oligomix (1.20% B, 0.10% Cu, 4% Fe, 1.50% Mn, 0.10% Mo, 2% Zn). Total 240 plants per cultivar were included. At the end, soil fertilizing with the fertilizer Polyfeed 11-44-11+ME (Fe, B, Zn, Mn, Co, Mo) was done (450 kg/ha). Before setting up the experiment, soil agrochemical analyses were done and good fertility with nitrogen and potassium, while medium fertility with phosphorus was determined. The foliar fertilizing had a positive influence on the yield of analyzed almond cultivars. The highest average content of fruit yield (2794 kg/ha for feranjez cultivar, 2699 kg/ha for texas cultivar and 2781 kg/ha for primorski cultivar) and the highest average kernels yield (1079 kg/ha for feranjez cultivar, 1333.50 for texas cultivar and 1257.30 kg/ha for primorski cultivar) were determined in the variant 2 treated with the fertilizer Ever green with Me. This study explored and determined how to achieves minimization of economic losses, but also ecological production and preservation of the environment, on the other hand, and all of that with proper use of foliar fertilizers.
