Growing carrots during the Brazilian summer requires extra attention to climate, plant health, and root quality. High temperatures, irregular rainfall, and periods of high humidity increase the risks to the crop, while the producer needs to balance productivity, commercial standards, and operational efficiency.
Under these conditions, higher production does not always translate into a better economic outcome. The commercial use of the roots throughout the supply chain also influences the return obtained by the producer.
“The challenge today is to seek productivity, but with stability and quality. The producer needs to think not only about the volume harvested, but about how much of that production actually becomes a commercial product,” says bulb and root specialist Samuel Sant'Anna.
During the summer, the combination of heat, rain, and humidity favors the development and spread of diseases in carrots. Among the problems is the leaf blight complex, associated with pathogens such as Alternaria dauci, Cercospora carotae, and Xanthomonas hortorum pv. carotae, as well as nematodes.
Although symptoms appear mainly in the aerial parts of the body, especially the leaves, the effects can compromise root development and reduce productivity in the field.
The risk doesn't end in the field. After harvesting, carrots go through stages such as transportation, washing, sorting, packaging, and distribution. In this process, characteristics like size, shape, uniformity, and appearance influence commercial viability.
Roots that do not meet the market standard may be discarded or sold for lower prices. Therefore, the quality of the roots becomes as important as the volume produced. “There is a significant difference between productivity per hectare and commercial production per hectare. A crop can produce well and still suffer losses when some of the roots do not meet the market standards,” Sant'Anna points out.
Operational efficiency has also gained importance in carrot cultivation. The pressure for greater efficiency has accelerated the mechanization of operations, mainly due to labor shortages and the need to increase speed in the field.
In this process, agronomic characteristics and plant architecture become increasingly important. The development of materials adapted to more mechanized systems accompanies the transformation of the activity. "The evolution of genetics accompanies the transformation of the carrot production and harvesting system, which is becoming progressively more mechanized," says Sant'Anna.
In this scenario, genetics can be used as a risk management tool. It does not eliminate the effects of climate nor replace proper management, but it can bring together characteristics capable of reducing the crop's exposure to the main challenges of summer cultivation.
It is within this perspective that the Solar F1 carrot, a summer hybrid from TSV Seeds, fits. According to information in the material, the cultivar was developed for more challenging conditions and combines high resistance to leaf blight complex and high tolerance to nematode attack.
The material also features characteristics focused on the quality and standardization of the roots. Solar F1 has cylindrical roots, smooth and shiny skin, intense orange inner color, small heart, and shoulder and tip closure.
Uniformity and high output in the washer are also highlighted as characteristics of the hybrid. Its upright growth habit and vigorous foliage complete the set of attributes related to operational efficiency.
Thus, in summer carrot cultivation, the combination of management, health, productivity, quality, and operational efficiency becomes important to reduce risks and increase the commercial viability of the production.
