Abstract: Currently, the most important task of stubble catch crops, as an element of sustainable agriculture, is to provide the soil with organic matter. The basic problem in the implementation of this task is the shortage of precipitation during the sowing period, which, combined with high temperatures in Europe in August, results in the loss of soil water and, consequently, weakening of germination and delay in plant emergence. The development of agrotechnics to increase the reliability of germination of seeds of plants grown as a catch crops is very important for the use of this valuable source of organic matter in regions with low and irregular rainfall, especially in the case of light soils with low water retention capacity. The aim of the study was to evaluate the response to furrow sowing of plants from various botanical groups grown as a stubble catch crop. Field studies were carried out on lessive soil in 2013–2015 at the Research Station in Mochełek near Bydgoszcz. The subject of the research was the sowing method (factor I): furrow sowing versus traditional (row) sowing. Sowing methods were tested for four crops (factor II): white mustard, tansy phacelia, common buckwheat, and common vetch. Certain plants reacted differently to the use of furrow sowing, and this reaction was different in various years of the study. In years with average soil moisture during the sowing period, furrow sowing made it possible to increase the yield of green mass and post-harvest residues of catch crop. In a year with very low soil moisture in this period, the desired effect of this method was not obtained. Furrow sowing allows seeds to be placed in a deeper, more moist soil layer, which can contribute to the acceleration of plant emergence. However, it requires refinement in terms of the precision of covering the sown seeds with soil.
