Foliar fertilization in shaping the potato yield in the conditions of south-eastern Poland

Abstract

The study aimed at determining the effect of macro- and microelements contained in foliar fertilizers on potato productivity of tubers. The field experiment was conducted in 2015–2017 in Uhnin using the random blocks method. The first order factor were 2 cultivars of potatoes, the second order factor were 3 foliar fertilization technologies and standard object − without foliar spraying. Mineral fertilizers were constant. Foliar fertilization contributed to the increase in overall and commercial potato tuber yield. Varieties and weather conditions in the years of research also had a significant impact on the tuber yields obtained.
