The reaction of spring wheat to the introduction of winter rye straw in a crop rotation with different types of fallow

The yield data of spring wheat cultivated in a crop rotation after winter rye with straw entering is presented. The work is part of the research of stationary field experiment on the study of primary tillage systems (factor A): dump (control), and non-moldboard. The experimental design (factor B) represents different types of fallows (2014) in combination with the introduction of winter rye straw in 2015 and 2018: 1 - pure fallow (control); 2 - pure fallow + straw; 3 - pure fallow + cattle manure 60 t/ha; 4 - pure fallow + manure + straw; 5 - green-manured fallow (white mustard) + straw; 6 - green-manured fallow (clover 1 year of use) + straw. Types of fallow with straw are split (factor C) by the addition of nitrogen. The straw introduction in the rotation with clean fallow reduced the wheat yield, regardless of the tillage system and the nitrogen introduction at the beginning of rotation by 4.8%, at the end - 15.6%. The use of green-manured mustard and clover fallows, the manure introduction into fallow reduced the depressive effect of straw on wheat productivity by 4...
