Abstract

In a pot experiment, the influence of interacton between spring wheat and spring barley on content of nitrogen, phosphorus and potassium in plants was assessed. The experiment was conducted according to the additive pattern. The experimental factors were: 1. the level of NPK mineral fertilisation: standard and the dose increased in relation to it by 50%; 2. method of plants sowing: in the mix and in pure stand. The plants for determination originated from 5 growth stages: germination, seedling growth, tillering, stem elongation, inflorescence emergence and ripening. It was shown that in the mix, as compared to pure stand cultivation, wheat contained less nitrogen and potassium during the inflorescence emergence and ripening stages and less phosphorus during germination and stem elongation. Mixed sowing increased the content of phosphorus in its mass during ripening and of potassium from germination until inflorescence emergence. Barley in the mix was characterised by a higher content of nitrogen during ripening and phosphorus during germination. In its over the ground parts a decrease in the accumulation of potassium during the period from germination until inflorescence formation was recorded.
