The second corn crop is entering the most critical phase of its cycle.

The field is now entering one of the most strategic moments for Brazilian agriculture: the beginning of the second corn crop planting. Every decision made in this short period directly influences the crop's performance throughout the entire cycle. The success of the second corn crop is directly linked to seed quality, hybrid suitability for the available planting window, and uniformity in planting.

According to agricultural engineer Marcos Boel, successful crop establishment begins even before sowing. “The key point is choosing the right hybrid, which needs to be adapted to the region, the planting date, and the level of investment the farmer is willing to make. The physical and physiological quality of the seed, planting weather conditions, and the technology involved, with well-regulated equipment, are also fundamental,” he states.

The ideal planting window, which normally extends from mid-January to the end of February, can be even shorter in years with delayed soybean harvests or irregular weather. “It’s a real race against time. A day's delay in planting can represent a significant loss of productivity at the end of the cycle. Therefore, the seed needs to be on the property in advance, ready for use, with high quality assured. The earlier the corn enters the field, the higher the yield potential,” he emphasizes.

The first signs that the second corn crop has started well appear soon after emergence. Stand count, emergence speed, and plant uniformity, which is directly related to factors such as bean size, germination, and seed vigor, are essential indicators. “Corn grows very quickly. Uneven emergence results in plants of different sizes, and one ends up dominating the other,” explains Boel.

Early crop monitoring is also essential. Pests such as stink bugs, caterpillars, and leafhoppers should be monitored from the first leaves. Good seed treatment is fundamental to protecting the plant in the initial stages, promoting uniform emergence and reducing risks from pests and diseases.

In recent years, second-crop corn has ceased to be a complementary crop and has become a key player in producer profitability. On many farms, it is the main source of income from the harvest. The crop has gained scale, technology, and economic importance. Even so, its productive potential is still largely untapped. "The potential of corn is enormous in Brazil, but we still explore very little of it. There is a long way to go to improve productivity, especially with more assertive planting decisions," he emphasizes.
