The robust growth of plants and the achievement of high yields on grain are closely related to rational nutrition to stages of tillering and culm elongation.
In particular, the sufficiency of Nitrogen influences decisively the evolution of the crop and determines the final height and the quality of production:
- ● At the stage of tillering, the presentation of Nitrogen and Phosphorus (from basic fertilization) promote the formation of productive tillers, increase the number of ears and total leaf area per hectare and create the conditions for high productivity of the crop.
- ● At the stage of culm elongation, the needs of plants for Nitrogen increasing. The adequacy of Nitrogen helps tillers to survive, increases the number of ears per hectare and the number of grains per ears, prolongs plant life and increases grain production.
