This paper deals with the results of the effects of low-input technology on grain yield of different winter wheat cultivars during the investigated period (2003/04 - 2004/05) on the chernozem luvic soil type in Faculty of Agriculture Belgrade-Zemun Experimental Field Radmilovac (Serbia). Conventional technology, which includes basic tillage with plow and high level of N had better effect than both investigated conservation tillage systems. Good results with mulch tillage means that may be one of possibilities for crop technology rationalization for winter wheat and soil conservation. No-tillage with no fertilization decrease grain yield especially without N fertilization. Fertilization with high nitrogen level (120 kg/ha) gives better grain yield compared with the other level (60 kg/ha). Low input cultivars of winter wheat especially Evropa, Lasta, NS Rana 5, and Pobeda positively responded to different technology in winter wheat production by their yield than high-input cultivars (Pesma and Rana Niska).
