The article presents the results of research on issues of improving the economic efficiency of technology elements for growing sweet corn of the variety Moreland F1 under conditions of Precarpathians of Ukraine. Taking into account the production strategy, have been outlined cost-effective resource-saving and intensive technologies which provide the stable yielding capacity of early-ripening hybrid of sweet corn under conditions of Precarpathians at the level of 4.99–6.65 t ha–1 accordingly with the profit of 370–500 € ha–1 and grain production profitability 112–135%. It is established that under the conditions of application of mineral fertilizers at the dose of N135P90K125 + N60 + N30 in two stages the grain yield of corn increases compared to the absolute control (by 2.26 t ha–1, or 30.3%) with increasing costs per 1 ha of sown area 68.23 €, or 26.4%). In proportion to the increase in yield, the amount of profit, which is 192.42 € ha–1, also increased significantly
