Abstract: Two-factor mulching researches have been conducted in 2004 - 2009. In 2011 the residual effect of organic mulches ia Aleksandras Stulginskis University (LUA) Pomological garden has been studied. Research treatments: A Factor - various organic mulches: 1) - no mulching (NE); 2) - wheat straw (SD); 3) - peat (DU); 4) - sawdust (PJ); 5) - grass (ZO). 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 the weeds germinated in the 3rd decade of May - 766 weeds number m"2 and 1st decade of June - 271 weeds number m"2. Different residue effect of mulches was established with annual and perennial weed regrowth. Applied organic mulches have stimulated (except straw and sawdust mulches) germination of annual weeds from 5.2 to 12.6 per cent. Perennial weed regrowth was stimulated by earlier applied straw mulches - 30.4 per cent and grass mulches - 5.6 per cent. Basic residual effect of mulch thickness has been established for annual weeds by 10 cm mulch thickness Earlier applied grass mulches have significantly increased the red beet yield (by 1.8 times), and sawdust mulches decreased significantly (by 4.6 times), compared with non mulched fields. Residual effect of organic mulch thickness on red beet yield was insignificant
