The Positive Effects of Mechanical and Chemical Treatments with the Application of Biostimulants in the Cultivation of Solanum tuberosum L.

The aim of the study was to determine effect mechanical and chemical treatments with application biostimulants on effectiveness weed infestation reduction potato yielding. A three-year field research conducted at Agricultural Experimental Station Zawady (52°03? N; 22°33? E). experiment set up in a split-plot design three replicates. first factor two edible cultivars, second five methods biostimulants: (1) control object—mechanical weeding, (2) herbicide Avatar 293 ZC (clomazone + metribuzin), (3) biostimulant PlonoStart, (4) Aminoplant, (5) Agro-Sorb Folium. Before emergence, object double ridging single harrowing after emergence. On other objects (2–5) before ridgings were applied. assessment performed using quantitative weight method dates: about 2 weeks tubers harvest. applied crop showed positive influence reducing number fresh weeds compared mechanical-only treatments. highest effectiveness, calculated basis mass weeds, found fifth object. It was, average, 70.5 71.6% for respectively. Research into use cultivation will continue due pro-environmental nature importance this crop. is certain that methodology future experiments meet challenges sustainable development.
