Results of study of the influence of preceding crops (spring rape (Brassica napus), blue lupine (Lupinus angustifolius) and spring wheat (Triticum aestivum)) on yielding capacity of spring triticale cultivated on sod-podzolic light loamy soils of the Republic of Belarus were presented. Research results showed that cultivated of spring triticale after the unfavourable for it preceding crop (spring rape) provided grain yielding capacity on 24,2-24,5% lower than in the conditions of its cultivation after blue lupine and spring wheat. Cultivation of spring triticale after the unfavourable stubble preceding crop caused the increasing of weed infestation or crops with cereal weeds (creeping wheat (Agropyrum repens), barnyard grass (Echinochloa crusgalli), hedge nettle (Stachys palustris), perennial sow thistle (Sonchus arvensis), dawny hemp nettle (Galeopsis tetrahit), corn mayweed (Matricaria inodora), field pansy (Viola arvensis), chickweed satin flower (Stellaria media), field pennycress (Thlaspi arvense)) and intensification of root rots development that rendered the lowering of yielding capacity of the productive haulm stand, grain quantity per head, and weight of 1000 grains of spring triticale. In course of two research years there were stated the highest indices of the productive haulm stand density lowering (up to 7-9%), while the indices of grain quantity per head, and weight of 1000 grains lowered up to 3-6% and 2-5%, respectively
