| Popis: |
The sources of nutrient accumulation in beans and bean seeds are the process of photosynthesis, root nutrition during the seed filling period, as well as the reutilization of substances accumulated in the vegetative organs in the previous period. The close dependence of the competition intensity on the number of plants per unit area of sowing is revealed. It was found that although increased nitrogen doses significantly reduce the competitive mutual inhibition of plants, it begins earlier than with a low nitrogen nutrition level. The main factor for which bean plants compete during the emergence-beginning of flowering phase under normal cultivation conditions is the available soil nitrogen. Therefore, the nitrogen fertilizers rational use leads to a more complete phenotypic manifestation of the vegetable beans genetically determined productivity. |
