Modern adaptive systems of basic main tillage under white mustard

Aim. To study the effect of long-term use primary soil treatment and fertilization systems on yield white mustard. The results research impact basic fertilizer economic efficiency mustard production in Forest-Steppe zone Ukraine are presented order to identify most effective, adapted natural climatic conditions recent years. Methods. was conducted during 2018–2021 a stationary two-factor field experiment, which includes 4 alternative (shelf, flat, chisel, disk) two systems: mineral (background 1) – N60P60K60 organo-mineral ) predecessor straw + N10 per 1 t N30Р30К30 short-rotation 4-field crop rotation with following alternation crops: soybean, spring barley, mustard, winter wheat. Results. It found that highest seeds 1.05 / ha provided by chisel system tillage against background fertilizer, exceeded control (shelf system) 0.1 t/ha (11%) similar rate fertilizers 0.13 (14%). Conclusion. Flat-cut terms prevailed 11% 17% 14%. In leaving ton application at dose N30P30K30 can be considered promising weather Against any shelf-free main for is more profitable than productive fertilizer. Production unprofitable all cultivation.
