Sažetak
The purpose of this study was to determine the effect of three foliar fertilizers (Epso Salt, Megagreen and Drin) and control treatment (with no foliar fertilizer) on the intensity of photosynthesis and chlorophyll content index in potato leaf. Research was conducted on a variety “Courage” in a greenhouse during two growing seasons (2006 and 2007). Foliar fertilizers were carried out five time during the growing seasons in the ten-day intervals in the period from the beginning of tuber formation to the stage of full tuberization. During the same period at intervals of five days measuring of the intensity of photosynthesis and chlorophyll content index have been conducted. The highest intensity of photosynthesis achieved control treatment and Megagreen. Foliar application of Epso Salt and Drin brought about significantly lower intensity of photosynthesis compared to control. Chlorophyll content index varied under the influence of treatments during the vegetation seasons. In 2006 there was no significant difference in chlorophyll content index between treatment Drin and control. Epso Salt and Megagreen achieved significantly lower chlorophyll content index in relation to control. In 2007 treatment Drin achieved significantly higher chlorophyll content index compared to control. There were no differences in chlorophyll content index between Epso Salt, Megagreen and control.
