Abstract
Summary The aim of this study was to determine the effect o f nitrogen fertilization desisting in winter wheat depending on water conditions. The experiment was carried out at Zotn iki Experimental Station that belongs to University of Life Sciences in Pozna n on a sandy loam soil classified as Albic Luvisols in 2000-2007. Treatments included water variant (ir rigated, non irrigated) and two levels of nitrogen fertilization (0 and 100 kg N·ha -1 ). It turn out that all the years of research had higher average of temperature than many-year average, espe cially during the period May-July. Terms of rainfal l were recorded 4 years of higher and 4 years of lower than many-year average. Desisting of nitrogen fertilization resul ted in the decrease of grain yield of winter wheat, variety Roma, grown un der natural conditions to 1.5 t·ha -1 (41%), and sprinkling irrigation to 2.03 t·ha -1 (52%). Sprinkling irrigation, under not nitrogen fincrease average grain yield of 0.23 t -1 (6.3%), and under nitrogen fertilization of 0.76 t·ha -1 (14.7%).
