Changes in the quality of green mass and pea grain depending on the use of microfertilisers and ammonium sulphate.

Abstract

All microelements, except zinc, increased pea grains' protein content over the years of research. The highest protein content in the green mass of peas was obtained by applying ammonium sulphate – 17.6%, boron – 16.5%, and molybdenum – 16.9%. The increase in protein content in the vegetative and grain parts of peas can be explained by an increase in the number and weight of leaves. In our study, we observed an increase in leaf weight and size in pea plants under the influence of ammonium sulphate and trace elements.
