Abstract

The paper presents the results of researches carried out over 2002–2006 which aimed at describing the influence of the follow-up action of undersown crops and spring barley straw on yielding and structure of yield of winter triticale. Two factors were examined. I. – undersown crop: control object (without undersown crop), white clover, white clover + Italian ryegrass, birdsfood trefoil, birdsfoot trefoil + Italian ryegass. Straw: without straw, with straw. Undersown crops were sown into spring barley which was cultivated on grain. In the first year after undersown crops and straw applying the some potatoes were cultivated, in the second year winter triticale was cultivated. The results pointed that, the highest number of dry mass and macroelements undersown crops inserted to the soil which were applied with straw. The highest yield of grain was achieved from winter triticale which was cultivated in the second year after applying of legume species mixtures with straw and after Italian ryegrass applied also with straw. On objects where the highest yield of grain was achieved also the highest number of ears per, the number of grain in ear and weighet of 1000 grains were noted.
