Abstract

In a field experiment with durum wheat the effect soil humidity and mineral nutrition on yield and yielding capacity of seeds was studied. The results of investigation showed that high doses of fertilizers is mainly to have a impact on yield, while the yielding capacity thus obtained seeds does not depend on them. In contrast to former the main factor modifying the quality of seeds is the level of soil moisture. Under the conditions of the water deficit of soil the seeds were reproduced with low yielding quality. Thus, yield and yielding capacity of seeds obtained by such way are independent parameters and have a different nature.
