Economic evaluation of weed control and nutrition of potato plants with the use of biostimulators

The results of a three-year field experiment in the cultivation of the edible potato of the Oberon cultivar with the use of five methods of weed control and nutrition with biostimulators were presented: control object – mechanical care, Avatar 293 ZC (chlomazone + metribuzin), Avatar 293 ZC and PlonoStart, Avatar 293 ZC and Aminoplant and Avatar 293 ZC and Agro-Sorb Folium in a split-plot system, two-factor in three repetitions. The aim of the study was to analyze the economic effectiveness of five methods of care and nutrition with biostimulators in combating weed infestation on a potato plantation of the Oberon cultivar carried out on medium soil, which was determined on the basis of indicators adopted in plant protection, such as: cost coverage index Wpk, which was on average 3.75 and profitability ratios E1 and E2, which averaged 20.34 and 5.68%. Profitability ratios showed that the mechanical and chemical protection of potatoes of the Oberon variety with the use of herbicide and biostimulators was profitable.
