One of the economically significant issues that accompany rice production is the increase of productivity through foliar treatments. The aim of the study is to evaluate the economic results from the application of foliar treatment in the production of 6 cultivars of rice - Bulgarian and introduced ones. The level of cost of rice production for 96 commonly tested variants has been established, including for 72 variants to which Folur, Amalgerol and Lithovit leaf treatments were applied. Performance indicators, cost-effectiveness thresholds and the factors that determine them are analyzed. All variants of paddy rice production, using foliar treatments have been found to provide positive economic benefits. Sufficient profit per unit area and profitability in the range of 10 to 18.40% was realized. The critical yield of production for them is 40-55% of the actual production per unit area.
