Abstract:

Experiments on methods of perennial weed control were carried out at the Kazliškiai organic farm of Lithuanian University of Agriculture in the period 2002-2003. The aim of the work was to investigate the influence of conventional ‘cultural’ cylindrical and two-layer plough technologies on perennial weed control in organic agriculture. The advantage of two-layer ploughing in decreasing perennial weed density and biomass in spring wheat and buckwheat crop was established. Elytrigia repens, Cirsium arvense, Tussilago farfara and Plantago major density and biomass had a tendency to decrease in different years of the trial.

Abstract:

Experiments were carried out at the Kazliškiai organic farm of the Lithuanian University of Agriculture in the period of 2002–2003. The aim of the work was to investigate elements of non-chemical weed control methods as main soil tillage, pre-sowing and post-sowing tillage. According to theoretical preconditions and data of the experiment, it is proved that total turnover of the layer in organic agriculture is a very important means of weed control decreasing weediness of the crop and increasing harvest. Two types of plough in combination with different pre-sowing and post-sowing soil tillage implements and technologies in crops of spring wheat and buckwheat were investigated. Spring wheat crops were grown comprising two varieties differing in plant height for additional investigations of their crop smothering power for weeds. It was proven that, for weed control, two-layer ploughing technology was favourable to conventional ‘cultural’ ploughing technology and that taller varieties had greater smothering power for weeds than shorter ones.
