Abstract
Subject of the research – white cabbage (Brassica oleraceae L. var. capitata L. f. alba) crop in plots previously mulched with organic mulches. Two-factor mulching experiment has been conducted in 2004–2009 in Aleksandras Stulginskis University Pomological garden. In 2012 the residual effect of organic mulches has been studied. Research treatments: Factor A – organic mulches: 1) – no mulching (WM); 2) – straw (ST); 3) – peat (PT); 4) – sawdust (SD); 5) – grass (GR). Factor B – thickness of mulch layer: 1) – 5 cm; 2) – 10 cm. Soil – drained medium-textured loam on clay loam calcareous moraine – Calc(ar)i-Endohypogleyic Luvisol. Most of short–lived weeds sprounted in the previously grass mulched plots – 848 units m-2, i.e., 1,3 times increase com-pared with non mulched plots. The least amount of short – lived weeds sprouted in the fields where previously sawdust mulch has been inserted, i.e. 3,7 precent less compared to non mulched fields. In previous years added peat, straw and sawdust mulches tended to decrease (from 7,7 to 15,8 precent), perennial weeds regeneration, compared with non mul-ched soil. The residual effect of the thickness of mulch layer on short – lived and perennial weeds were minor. Previously inserted grass mulch increased white cabbage yield by 1,3 times and sawdust mulch significantly by 1,9 times reduced cabbage yield compared to non mulched fields. The residual effect of the thickness of organic mulches layer on white cabbage yield was not significant.
