Brazilian agribusiness, a fundamental pillar of the national economy, stands out globally for its productive capacity and innovation. Within this scenario, coffee farming takes on a leading role, generating jobs, income and foreign exchange for the country. However, the search for productivity and quality in coffee is a constant challenge, especially when it comes to nutritional management in critical stages of the plant's development. One of the most significant bottlenecks is low flower set, which can severely compromise the harvest. Inadequate nutrition, particularly micronutrient deficiency, is a key factor in this problem. Route Chemicals, aware of this reality, presents an innovative and scientifically proven solution to optimize flower setting and ensure stable productivity: specific pre-flowering nutrition with Route micronutrients, with emphasis on Route Boron 10 Fertilizer.
The pre-flowering phase in coffee plants is a period of high energy and nutritional demand, crucial for establishing the crop's productive potential. Deficiency of micronutrients, especially boron (B), is one of the main limiting factors for the success of flowering and fruit setting. Boron performs vital functions in the plant, such as the formation of the cell wall, the transport of sugars, cell division and, fundamentally, the germination of the pollen grain and the growth of the pollen tube [1, 2]. The absence or low availability of this micronutrient directly compromises the fertilization of flowers, resulting in floral abortion and, consequently, a drastic reduction in the number of fruits per plant.
Studies show that boron deficiency can lead to significant productivity losses. In coffee trees, a lack of boron can cause poor flower formation, pollen sterility and fertilization failure, impacting fruit set by up to 30% or more, depending on the severity of the deficiency and environmental conditions [3]. The average productivity of coffee plantations in Brazil, which is around 25-30 bags/hectare, can be substantially increased with adequate nutritional management, aiming to reach levels of 40-50 bags/hectare or more in high-performance crops.
Route Chemicals offers the Boro 10 Route Fertilizer, a high-tech solution developed to efficiently meet the coffee plant's boron needs. With 10% Boron (B) w/w (130 g/L w/v) and chelated formulation, Boron 10 Route guarantees high foliar absorption, optimizing nutrient translocation to points of greatest demand, such as floral tissues and growing tips [4]. Its physical nature in suspension and the raw material (boric acid) ensure the stability and effectiveness of the product.
The recommended application method for coffee is foliar, at a dosage of 0.5 to 1 L/ha. The ideal application time is at the beginning of flowering and at the time of petal fall, moments when the demand for boron is maximum and the plant is most receptive to foliar absorption. To further optimize application efficiency, it is recommended to use Route adjuvants, which improve the spreadability, adhesion and penetration of the mixture, reducing losses due to drift and leaching. The application methodology must follow good agricultural practices, using calibrated spray equipment to ensure uniform coverage of the foliage.
With the strategic application of Boro 10 Route Fertilizer, the expected results are quantifiable and directly impact the producer's profitability. An increase in the setting of flowers and fruits is expected, resulting in an increase in productivity that can vary from 10% to 20% in crops with boron deficiency, or even more in severe cases. This translates into a greater number of grains per plant, greater grain weight and, consequently, a more robust and profitable harvest. Furthermore, the improvement in fruit quality and the uniformity of maturation are additional benefits that add value to production.
