Comparative Evaluation of Mineral and Organo-Mineral Nitrogen Fertilization and the Role of Amino Acids as Plant Growth Promoters in Maize Cultivation

The challenge to increase nitrogen uptake efficiency in intensively cultivated soils without runoffs and atmospheric release has been difficult handle usually leads the excess application of mineral fertilizers. In present study, four combinations two different N fertilizers a control were used maize cultivation evaluate use types fertilization case agronomic plant physiology characteristics, as well quantity quality characteristics maize’s yield. results show that, when full rate with addition half organo-mineral fertilizer amino acids (MF+OMAA/2) was used, presented 16% yield comparison control, followed by (MF) 10% increase. Protein content increased all treatments 3–6% compared conventional alternates lower rates not differing significantly. leaves both measurements (11–23% 19–40% at 70 107 days after sowing, respectively) control. this study confirm that containing can be an alternative or additive decrease result improved seed productivity protein farms.
