ABSTRACT



The research aimed at defining the variability in the yielding of yellow lupin cultivated in pure stand and in mixtures with spring triticale in a field experiment at a varied April-July rainfall as well as a varied sowing density of both components. The experiments were carried out over 1990-1993 at the Mochełek Experiment Station of the Bydgoszcz University of Technology and Agriculture, Faculty of Agriculture. The experiments were conducted on light soil of a good rye soil suitability complex, IVa soil quality classification. The value of the rainfall variability coefficient over April-July amounted to 37.1%. The driest period rainfall amounted to 106 mm, while the most moisten period rainfall - 260 mm. It was observed that the yellow lupin yielding variability in pure stand was considerably lower than in the mixtures with spring triticale. An increasing lupin sowing density from 25 to 50-100 seeds per 1 m2, both in pure stand and in mixtures, showed a stabilising effect on the seed yield and pl
