Impact of growth biostimulators and herbicide on edible potato yield

Abstract

5, in which mechanical tillage was used prior to seeding, and after the ultimate formation of furrows before seeding of potato plants, Avatar herbicide 293 was applied in a dose of 1.5 dm3 ha–1 (total yield amounted to, on average, 40.6 t ha–1). Potato cultivars cultivated in the experiment and meteorological conditions during the conducted tests also had a significant impact on the size of the total yield. Cultivar Owacja produced the highest yields (an average of 41.4 t ha–1). The largest total yield was collected in 2016 (an average of 42.8 t ha–1). A significant influence of the experimental factors on the structure of large tuber yields was also found. K e y w o r d s: potato, total yield, biostimulators, herbicide
