Economic effectiveness of using various methods of care and nutrition of potato plants with the use of biostimulants

Abstract

The aim of the research was the economic evaluation of five methods of care and nutrition with biostimulants: control object – mechanical care, Avatar 293 ZC (clomazone + metribuzin), Avatar 293 ZC and PlonoStart, Avatar 293 ZC and Aminoplant as well as Avatar 293 ZC and Agro-Sorb Folium in combating weed infestation in food potato plantations. The research material consisted of potato tubers of the Malaga variety coming from a three-year field experiment carried out on medium soil, in a split-plot system, as a two-factorial experiment in three replications. The economic effects of using various methods of care and nutrition of potato plants with the use of biostimulants were determined on the basis of the indicative profitability ratios E1 and E2, and the cost coverage ratio Wpk, which were on average E1 (21.04), E2 (6.88%), Wpk (3.88). The commercial yield increased by 37.4% on average.
