Nitrogen is considered the limiting nutrient for maize plants because it controls production, it is the nutrient that the plant needs most. Plants that are properly fertilized will give higher yields. Nitrogen captured by maize plants accumulates in stems and leaves, promoting photosynthesis.
This promotes yield growth, especially during flowering, which is directly related to the amount of seeds per cob.
Increased nitrogen availability also has a positive effect on grain filling. Nutrients, including nitrogen, accumulate in the stems and leaves that move toward the seeds. Nitrogen stored in grains is essential to continue growing. In conditions of low fertility, this characteristic would define the level of yield achievable by the crop. Therefore, increasing the dose of nitrogen will increase the mass and the volume of maize grains as well as the filling time of the grains.
PERFECT DOSING=PERFECT PRODUCTION
There is scientific evidence of the direct relationship between nitrogen consumption and increased maize yield. However, the positive impact of nitrogen fertilisation on crops depends on several aspects:
- Environment: climatic and ecological conditions, application time.
- Biological: plant needs, reactivity of genetic material.
- Cultural work: Sowing system, sowing density, crop system, crop rotation, irrigation system, cost and profits, time, and method of application.
- Chemistry: A source of nitrogen. The forms of nitrogen used by plants are nitrate (N03″) and ammonium (NH4+) ions, and their absorption is based on soil pH, temperature and the presence of other ions in the soil solution.
It is proven that the efficiency of nitrogen varies, depending on the location and the cultural work carried out. Even fertilisation with nitrogen might have no effect or reduce the yield if not done properly.
Nitrogen is a nutrient that significantly increases yield, helping the plant have a better structure. Nitrogenous fertilisation combined with sulphur is the perfect duo for disease prevention.
