abstract:
In environment studies performed in the Lublin region in the period of 1997-2006, the relationship between winter wheat yields and some soil properties (pHKCl, grain size composition, contents of Corg and available forms of P, K, Mg and N-NH4, and N-NO3) and agricultural practices (N fertilisation, forecrop, variety) was assessed. The results were obtained after chemical analyses (soil properties) and interviews with farmers at 199 farms. Gathered data were statistically analysed with the methods of analysis of variance and multiple regression. Winter wheat yielding was significantly dependent on the dose of nitrogen, variety and years of cultivation. The highest yield of winter wheat was harvested on plots after pea and winter rape. Application of other forecrops (oats, spring barley and crop blend) resulted in significantly lower yields of wheat. Multiple regression indicated that assessed soil properties (contents of fine particles, humus, available Mg, K, P and mineral forms of N) accounted for the level of wheat yields in around 50%.
