RESEARCH ON ADDITIONAL FERTILIZATION IN EARLY POTATO CROP ON SAND SOIL

Abstract

The early potato is one of the most profitable crops. It must be cultivated only in those areas where the environmental factors are favorable for achieving large productions, and the southern area of Oltenia meets the necessary conditions required by the plant's biology. The researches followed the efficiency of the foliar fertilization as well as the behavior of the early potato plants regarding the realized production, depending on the administered dose. The use of foliar fertilizers on early potato has led to increased yields in all variants. By applying the ATON ZN product, the production of tubers achieved in 2021, of 36266 Kg/ha, was superior to the untreated control by 11100 Kg/ha, which means an increase of 44.1%. By applying the SEACTIV SILVER product, the production of tubers achieved in 2021, of 32166 Kg/ha, was superior to the untreated control by 7000 Kg/ha, which means an increase of 27.8%. The increase in production was achieved due to the increase in the average weight of the tubers from the variant treated with SEACTIV SILVER, which was statistically assured as distinctly significant positive.
