Does foliar nicotinamide application affect second crop corn (Zea mays)?

The largest corn yeld in Brazil is currently the second harvest, which most susceptible period to climatic adversities occurring during cycle. Thus, introducing beneficial elements for maintaining adequate development of plant can help producers obtaining greater kernel yields. Among studied elements, nicotinamide has potential use since it associated with accumulating secondary metabolites and manifesting defence metabolism plants. objective this work was evaluate influence applied different doses (only once or instalments) on biometric productive characteristics corn. treatments were composed by number applications (one two) five (0, 50, 100, 150 200 mg L-1). Plant diameter, height, ear insertion leaf area dry matter, yield 100-kernel mass evaluated. It found that close 100 L-1 resulted increases vegetative reproductive development, regardless applications. In way, foliar application positively influences crop Highlights plants improves its growth, components grain yield. A single stage V3 at a dose sufficient increase Corn be increased 12.6% nicotinamide. There no need two crop.
