The effect of different tillage methods on soil agrophysical properties, water regime, weed infestation, as well as on growth and development, yield and economic efficiency of spring barley (Ilot variety) cultivation under the conditions of the Ukrainian Northern Steppe was studied. Experimental researches were carried out during 2011-2013 in a short crop rotation system: bare fallow - winter wheat - sunflower - spring barley - corn. The basic soil tillage for spring barley was performed using the plough PO-3-35 at a depth of 20-22 cm (control variant), chisel tillage – by Canadian chisel cultivator Conser Till Plow at a depth of 14-16 cm, and disc tillage –by heavy disk harrows BDT - 3 at a depth of 10-12 cm. It was found that chisel tillage provides the best conditions for moisture accumulation in the autumn-winter period due to crop residues and wavy nanorelief that ensures the
maximum amount of moisture storage in spring compared to other tillage methods. Moldboard ploughing and chisel tillage influence the formation of the highest and almost identical grain yield – 2.51-2.90 and 2.36-2.88 t/ha respectively, which favourably affects total costs and profitability of barley grain production - 44.7-48.7 %. |
