Sažetak
In conditions of Ulcinjsko polje, during the period 1987-1991, growth intensity of one-year old olive shoots and fruit growth in Picholine variety were investigated. Related to that, the dynamics of mineral nutrition (N, P, K, Ca and Mg) was followed in leaves and fruits in the period from middle of July to the middle of October. Results showed that nutrient status during vegetation period was within optimal values for olive. Decreasing dynamics during vegetative period was in N (from 2.22% to 1.67%). Slight increasing dynamic was showed in K (1.15% to 1.32%), Ca (0.91% to 1.22%) and Mg (0.17% to 0.21%), while P had a relatively stable content in olive leaves (0.19%). Nutrient status in the fruit showed different tendencies. Decreasing dynamics showed N (0.81 to 0.59%), Ca (260 to 229 ppm) and Mg (228 to 191 ppm). Slight increment showed P (0.13 do 015%) and K (1.44 do 1.51 %).
