Yield of soy and efficiency of its cultivation under different systems of main tillage and fertilizer

Aim. To determine the effect of long-term use various systems basic tillage and fertilization on productivity soybean agrocenoses, efficiency its cultivation technologies. The article presents results research influence main soil formation crop indicators economic production in conditions Forest-Steppe Ukraine with aim identifying most effective, adapted to weather that have developed recent years. Methods. Research was conducted during 2018–2021 a stationary two-factor field experiment, which includes 4 alternative (shelf, flat-cut, chisel, disk), two systems: mineral (background 1) – N60Р60К60; organo-mineral 2) - precursor straw + N10 / t N30Р30К30 short-rotational 4-field rotation following rotation: soybean, spring barley, white mustard, winter wheat. Results. highest yield 2.43 t/ha obtained under chisel system background organic-mineral fertilizer, exceeded control (shelf system) by 0.22 (10%) similar indicator fertilizer 0.05 (2%). All shelf-free outperformed 4-10% 2-13%. Conclusions. According soybeans, depth 25–27 cm against leaving wheat per ton introduction fertilizers dose N30Р30K30 turned out be climate years is promising for into production.
