ABSTRACT

Trends in global agriculture are expected to move towards an increase in the productivity of linseed, as an oil crop with a valuable composition of unsaturated fatty acids. It is thought that a new agrotechnical approach diversifying linseed cultivation may increase crop yields. The aim of the study was to compare linseed cultivation in pure stand and in mixture with wheat in new sowing proportions (75+25%, 50+50% and 25+75%).
Mixed intercropping of linseed with wheat significantly decreased the length of the inflorescence, which was followed by a decrease in the number of branches and capsules. The spikes of spring wheat were longer in the two-species mixture, which resulted in a greater number of spikelets and grains. In the pure stand, the seed yield (g m^-2) for linseed was 297.7, while that of spring wheat was 546.4. The percentage of linseed in the seed yield for the mixtures with a 75, 50 and 25% share of linseed in the mixture was 41.1, 17.7 and 4.9%, respectively. High productivity of linseed in a mixture can be obtained only when its share is optimal (at least 75%). However, the total productivity of components in two-species mixture is lower by about 28% in comparison to pure stand which, from practical point of view, is not excellent agrotechnical solution. The correct proportion of species in a two-species mixture is the most important aspect of plant productivity.

Key words: competition indices, morphological traits, yield components.
