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 yieid of wheat. in this study mineral fertilization 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.
