Abstract
This work presents the three-year results of the effects of mineral and different types of organic fertilizers on the elements of the yield (the relative coefficient of fertility, the absolute coefficient of fertility, cluster weight and the yield of grapes per area unit) of the Vranac variety of grape. The research was carried out in Podgorica vineyard, at the location Ljeskopolje. Eight different variants of nutrition were applied: (1) control (without fertilization); (2) NPK (8:16:24) - 500 kg/ha; (3) cow manure - 20 t/ha; (4) poultry manure - 10 t/ha; (5) peat - 10 t/ha; (6) cow manure + poultry manure - 10 + 5 t/ha; (7) cow manure + peat - 10 + 5 t/ha; (8) poultry manure + peat - 5 + 5 t/ha. All the variants of nutrition were tested under irrigated and non-irrigated conditions. The results showed that the relative coefficient of fertility in all the tested variants of nutrition had high values. Regarding the number of inflorescences per productive shoot in a three-year average, a particularly good variant was the cow manure and the variant with the combination of poultry manure and peat. The application of mineral and different types of organic fertilizers had a positive effect on the average cluster weight. The variant with the combination of poultry manure and peat gave the highest average cluster weight in the three-year average. All the tested variants of nutrition in the three-year average had a higher yield than the variant without fertilization. The variant with cow manure had the highest yield of grapes. Irrigation had a positive effect on all the tested indicators of the yield.
