The paper deals with adaptations in winter wheat technology from high level inputs to a significant reduction of production costs and a maximum reliance upon natural resources on the weed infestation and grain yield of different cultivars. These adaptations must first and foremost build resilience within agroecosystem, increasing its ability to continue functioning when faced with unexpected events. Winter wheat technology consists from the following tillage systems: conventional, mulch tillage and no-tillage. Plots were fertilized with two nitrogen amount: rational level (60 kg ha -1) and high level (120 kg ha -1). Six Serbian cultivars were included in the trial. Four of them were chosen for low-input and two for high-input technology. Different tillage systems, nitrogen level and cultivars applied in four-year crop rotation (maize-winter wheat-spring barley+red clover-red clover). Winter wheat technology based on conventional tillage systems had better effect on weed control than both conservation tillage systems (mulch and no-till.). Low-input cultivars of winter wheat positively responded to different tillage systems and nitrogen level by their yield than high-input cultivars.
