The effect of fertilizing on the yield of Primorski almond cultivar grown in Valandovo region in the period of the year from 2012 to 2013 was determined. The experiment was set in four variants and three repetitions. The variants were: Control (untreated); NPK+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); NPK+Biolinfa (34% organic matter 3% N, 5.80% K2O) and NPK+Oligomix (1.20% B, 0.10% Cu, 4% Fe, 1.50% Mn, 0.10% Mo, 2% Zn).
The distance of fruit planting was 4.5 m row by row and 3.5 m in the rows. In each variant and repetition were included 20 plants, and total in all experiment were involved 240 plants. Three foliar treatments were applied with given above fertilizers at a concentration of 0.4%. In the end of the November, soil fertilizing with the fertilizer Polyfeed 11-44-11+ME (Fe, B, Zn, Mn, Co, Mo) in quantity amount of 450 kg ha-1 was done.
Before setting up the experiment, soil agrochemical analyses were made, and was concluded good fertility with nitrogen, medium fertility with phosphorus and potassium. The foliar fertilizing has had a positive influence on the yield in all variants, treated with different kinds of fertilizers, compared with the control, untreated variant.
The highest average content of almond fruit yield (2781 kg ha-1) and the highest average almond kernels yield (1257.30 kg ha-1) was determined in the variant 2 treated with fertilizer NPK+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). The lowest almond fruits yield (1822 kg ha-1) and the lowest almond kernels yield (806.45 kg ha-1) was determined in the control variant.
