Winter wheat management practice in PIK Vinkovci d.d. and weather characteristics in the period from 2010 to 2012

Winter wheat is, after maize, the second-ranked field crop in Croatia (149797 ha or 16.8% of cultivated arable land of the country: status 2011). Annual yield variation of wheat in the 2006-2010 period i Croatia were from 4-0 to 5.5 t/ha. There are indications that low wheat yields in Croatia are mainly associated with precipitation excess, especially during autumn/winter period and drought stress in spring. Aim of this study was testing management practices and yields of winter wheat on PIK Vinkovci d.d. (Vukovar-Syrmium County) in the period from 2010 to 2012 with emphasis on weather characteristics effects. The growing season 2009/2010 was less favorable for winter wheat growing mainly due to excessive precipitation. For example, precipitation in the October-June period (Gradiste Weather Bureau) were close to double higher than in the 2010/2011 and the 2011/2012 growing season and for 57% higher compared to the long-term (1971- 1990) average. Mean yields of wheat on PIK Vinkovci d.d. were 6.12 t/ha (1155 ha), 6.86 t/ha (889 ha) and 7.76 t/ha (1218 ha), for 2010, 2011, and 2012, respectively. Srpanjka and Lucija are dominant cultivars on PIK Vinkovci and they covered 61%, 78% and 90% of total harvested area, for 2010, 2011, and 2012, respectively.
