Event in the west of São Paulo debates nutrition and physiology of peanuts

peanut producers, technicians and students from Unoeste, in Presidente Prudente (SP), will be gathered on January 20, in Regente Feijó, in the west of São Paulo, in an event dedicated to the peanut. The region is one of the main areas focused on culture in the State of São Paul.

On Peanut Day II, promoted by professors Fábio Rafael Echer and Carlos Felipe dos Santos Cordeiro, of Unoeste, in partnership with ICL, a company that uses its resources exclusive capabilities and technological capacity to develop impactful solutions in plant nutrition and physiology, the Nutritional Program Outperforms Peanut, whose main objective is deliver the best technologies and solutions in plant nutrition and physiology, helping to ensure that crops are always well nourished and prepared for overcome stress and express their genetic potential.

“Nitrogen is one of the nutrients required in greater quantities by the peanut crop and can be obtained at “zero cost” thanks to Biological Nitrogen Fixation (BNF). For six years, we studied in depth the physiology of nodulation, identified the factors that interfere in this process and we developed technology to enhance nitrogen fixation and metabolism in the plant. tone, as the name suggests, one of the constants in the Supera Amendoim Program, aims to tone the plant’s nodules and maintain nitrogen production throughout the crop cycle”, explains agronomist Aijânio Silva, from ICL.

Silva explains that among the benefits of technology are the continuous formation of young and strong nodules (photo), through modulation of hormonal balance; nitrogen fixation much more efficient, providing more energy for the plant to grow; the quick transformation of the nitrogen supplied by the nodules into proteins and more grains heavy; the supply of energy to the nodes; reducing ethylene formation in the plant, preventing premature death of the nodules; and the supply of essential elements to keep the nodules physiologically active.

“Peanut is a plant native to South America and has a great ability to associate with bacteria of the genus Rhizobium and thus perform biological nitrogen fixation (FBN). Modern peanut cultivars absorb up to 300 kg ha-1 of N and export in around 200 kg ha-1, and around 80% of this nitrogen comes from FBN. Thus, techniques such as inoculation and adequate nutrition, especially with cobalt, molybdenum and nickel improve the efficiency of FBN, nutrition with N, productivity and quality of peanuts produced. Search results carried out in the 2021/2022 harvest in partnership with ICL/Unoeste, reported increases of 18% in peanut productivity with application of Tonus in relation to control. This shows the importance of balanced nutrition to enhance the FBN in this culture and the need for new studies to improve the peanut productivity through mineral nutrition of plants”, explains the agronomist Carlos Cordeiro, organizer of II Peanut Day.
