Object of research – processes of formation of productivity and grain quality of cereal crops in short-rotation crop rotations under different systems of primary tillage. Objective of research – development of an optimal technology for growing winter wheat under the arid conditions of the Southern Steppe, depending on various systems of primary tillage in short-rotation crop rotations. Methods and conditions of research – field experiment with generally accepted observations; the principle of single difference was maintained; southern chernozem soil. Research results: It was established that:In the 1st and 2nd winter wheat crops following winter vetch green-manure fallow, the lowest average water consumption coefficient was observed – 55.0 and 62.5 mm/t, respectively. On average over two years of research, the lowest weed infestation was recorded after black fallow (56.5 plants/m²) and moldboard and no-till tillage systems. Across all experimental variants, winter vetch green-manure fallow affected winter wheat yield (4.26 t/ha) almost at the level of black fallow (4.21 t/ha). A positive effect on yield formation was observed under no-till tillage (4.41 t/ha). Tillage systems had little influence on the grain quality of winter wheat. Against the background of different primary tillage schemes, 3rd-class grain was obtained on average over two years. The best grain quality was achieved with no-till tillage (12.3% protein; 20.9% gluten). In the 1st and 2nd crops following black fallow and winter vetch green-manure fallow, both moldboard and no-till tillage resulted in 3rd-class grain in terms of protein and gluten content. In the 4th crop, all variants (except black fallow) produced 4th-class grain. The highest profitability level – 96.6% – was obtained when using winter vetch green-manure fallow as a predecessor combined with no-till tillage. Product Description popup.authors Svitlana I.
