Field Day in Bom Jesus will showcase new features in bean cultivation

One of the foods most consumed by Brazilians, but which still lacks information to improve and even expand its production, beans could be a good alternative to soybeans, as a crop rotation. With little research and information about its cultivation in Rio Grande do Sul, we stopped planting and learning about the varieties of this plant. This statement comes from Arns Pesquisa e Consultoria, which is holding Tech Feijão on March 1st, especially focused on this legume. The event takes place in Bom Jesus (RS), on the Três Marias farm, and is expected to bring together hundreds of participants, including exhibitors and producers who will have the opportunity to check out the news and products on display in the experimental plots grown on the property.

Tech Feijão will demonstrate varieties, fertilization, inoculation, seed treatment and fungicides. Specialized companies will expose what is new in each area for bean cultivation, including addressing soil care through the chemical balance necessary to enhance crop results.

One of the exhibitors at the event is SulGesso, a company from Santa Catarina that presents mineral fertilizer solutions, essential for achieving productive stability. Bean cultivation requires soils rich in organic matter and fertilizer elements to nourish the soil and, to this end, SulGesso developed SulfaCal, a granulated fertilizer based on calcium sulfate, with the macronutrients calcium and soluble sulfur. Producers across the country are experiencing the cost-benefit that this product offers, presenting several solutions in a single product: it helps to decompact the soil; rooting; reduction of toxic aluminum; crops more resistant to drought and, consequently, an increase in productivity.

Arns agronomist, Ingrid Arns, carried out experiments on beans with SulfaCal and observed satisfactory results. “Last year we carried out the test using SulfaCal alone and SulfaCal mixed with traditional fertilizer (MAP), as base fertilizer, with excellent results in both cases. And this year I repeated the experiment, using MAP alone and comparing it with the mixture of MAP plus SulfaCal”, explains Ingrid. In both experiments, SulfaCal proved to be superior from the beginning of crop development to the final result at harvest. In practice, the results appeared. In the experimental plots where only MAP fertilizer was used, the beans yielded 63 bags per hectare. In the plot that used only SulfaCal, the number was 66 bags/ha and the experiment where SulfaCal was used added to MAP, the result was 71 bags/ha. The experimental plot without any fertilizer yielded 61 bags per hectare. “We noticed that there is little difference when using just common fertilizer or leaving the plant without fertilizer. But, when mixed, the two fertilizers brought a much more satisfactory result”, adds the agronomist, who highlights the supply of calcium and sulfur from SulfaCal as the main effect, creating a synergy with the MAP phosphate fertilizer, presenting root effects up to the aerial view of the plant.

For SulGesso's technical director and agronomist, Eduardo Silva e Silva, the result of this experiment can be compared to soybean cultivation, as they are legumes from the same family. “The benefits are very similar, the difference is in the cycles and the amount that each one absorbs and exports calcium and sulfur per hectare”, explains Eduardo. In legumes, the presence of sulfur is essential, which helps the plant to nourish itself with nitrogen. “In the experiment carried out by Arns with beans, the result was practically 10 more bags per hectare when used together with SulfaCal and MAP. We can compare this with the effects that the product has on soybeans, because they are very similar plants”, adds the agronomist.

The region where Tech Feijão takes place, northeast of RS, is the largest producer of beans in the state, with around 30 thousand hectares cultivated in Vacaria alone. The event will be open to the public from 9 am and will last throughout the morning. To participate, simply contact Arns Pesquisa e Consultoria, on phone: (54) 3232 3516
