Nitrogen efficiency of winter wheat on different tillage methods for whole crops silage
Józef Sowiński , Wiesław Wojciechowski
AbstractField studies were carried out in the years 2011- 2014 at the Pawłowice Research Station belonging to the Wroclaw University of Environmental and Life Sciences. A traditional tillage system was compared with no-tillage into stubble and bi-cropping- no-tillage wheat on white clover living mulch. The measurements of dry matter, total protein and energy yields allowed us to determine the efficiency of nitrogen uptake. The efficiency of N fertilizer was determined in relation to yield given in metrical units and also protein and energy yields noted. The highest dry matter yield (7.38 t per ha) was observed at the traditional tillage system, and it was 14% higher than that obtained from bi-cropping and 43% higher than that from no-tillage into stubble. The most effective N fertilizer efficiency was found with a traditional tillage system. In contrast, the lowest N fertilizer efficiency was found on white clover wheat bi-cropping system. This proves that bi-cropping of winter wheat and fodder legumes can markedly reduce or even could eliminate the N fertilizer use.
