ABSTRACT
The results of three years of research concerned the assessment of the profitability of table potato production depending on the control of weed infestation and the use of biostimulants: 1. control object, 2. Avatar 293ZC (clomazone + metribuzin), 3. Avatar 293ZC + biostimulator PlonoStart, 4. Avatar 293ZC + biostimulator Aminoplant, 5. Avatar 293ZC + biostimulator Agro-Sorb-Folium. The research material consisted of potato tubers of the Malaga variety coming from a field experiment carried out in 2018-2020 on medium soil, in a split-plot arrangement, as two-factorial in three replications. Mechanical and chemical treatments increased the marketable yield of tubers by an average of 37.4%, and decreased the by-yield of tubers by an average of 23.9% compared to the control object. The direct surplus per 1 ha of cultivation ranged from PLN 3521.1 in the control object 1. to PLN 11277.9 in object 5. (herbicid + Agro-Sorb Folium).
