Uproszczenie uprawy roli oraz dolistne dokarmianie makro- i mikroelementami a zachwaszczenie soi uprawianej w monokulturze

TL;DRAbstract

The effect of two factors: reduced tillage systems and foliar nutrition on the status of weeds in soybean growing in monoculture on lessive loes soil (good-rye agricultural usefulness complex) in the 1998–2003, is presented in the paper. The experiment was carried out by split-block method and replicated three times on plots 35 m2 brutto and 20 m2 netto. The tillage treatment was conventional (I) and 3 kinds of reduced one: without post harvest cultivation (II); chisel+cultivator instead of ploughing (III); direct sowing (diquat 600 g ha-1 in spring prior to seed drilling) (IV). Foliar nutrition, by 2 l ha-1 of Florosol U (N –12; P –1.745; K – 4.981; Mg – 0.12; B – 0.012; Cu – 0.015; Fe – 0.018; Mn – 0.016; Mo – 0.002; Zn – 0.01 in % of mass), was performed twice: at 3–4 true soybean leaves and just after plant flowering. The crop was cultivated under other agrotechnical measures adjusted to its need with elementary (NPK) fertilization. Weeds were controlled by soil herbicides: linuron
