In order to determine the impact of influence result of basic soil for previous (spring pas) on wheat productivity in the period 2004 - 2008 is out of the Polish experience is out of the typical black earth soil type in the experimental field Maize Research Institute - Kneja. Following factors were studied. Tillage of soil: Peas with - ploughing 18 - 20 cm; flat - cut - 18 - 20 cm; loosening - 18 - 20 cm and disk - harrow - 10 - 12 and 6 - 8 cm wheat double disk-harrow - 10 - 12 and 6 - 8 cm.It was found that tillage of soil for the predecessor does not affect the magnitude of the yield of wheat. In this study mineral fertilisation a significant effect on grain yield. Fertilizing with N6P4 kg/da increased yield, compared to the control variant (B0)N0P0 kg/da and 35,29%; 35,54%; 33,58%; 40,49% and twice with N12P8 kg/da and 49,02%; 42,48%; 40,48%; 50,35% for A1, A2, A3 and A4.
