Priešsėlio įtaka žieminių rugių piktžolėtumui ir produktyvumui

Abstract

The field experiment was carried out at the Experimental Station of Aleksandras Stulginskis during 2015–2016. Soil – Endocalcari-Epihypogleyic Cambisol (sicco) (CMg-p-w-can). The influence of the preceding crop was investigated on the weedness and productivity of winter rye. The preceding crop had the significant influence on the weedness of winter rye but the yield hadn‘t significant difference. The amount and dry weight of weeds were significant higher in the monoculture than in other crop rotation. Monoculture‘s yield was about 20.1 percents higher than other crops which were grown after different preceding crop. Supposedly, the meteorological conditions had influence on monoculture. The humidity was too high during the vegetation period of winter rye. The hydrothermal coeficient (HTC) varied from 0 to 3.5 in each period). The least amount of weeds was established in three – course rotation after black follow.
