Produtividade agroindustrial da cana-de-açucar (Saccharum spp.) em diferentes sistemas de plantio

Abstract

Sugarcane is one of the main agricultural commodities produced in Brazil and accounts for a significant portion of Brazilian exports. In the Northeast of Brazil, sugarcane occupies a large area of coastal tablelands, where topography, depth and soil texture favor cultivation. Currently, the vertical planting technique has gained prominence in agricultural properties, even though it is a recent approach and still has few studies and results published. Thus, the objective of this study was to evaluate the production and technological quality of sugarcane according to the planting system, in the region of the Mata Alagoana region. The study was conducted under field conditions, in the experimental area belonging to the Luiz Jatobá group located in the municipality of São Miguel dos Campos-AL, on the Coité 2 farm. Vertical planting was conducted in an area of 5.64 ha, while the conventional planting system was in an area of 10.36 ha. In both systems, the variety RB08791 was used. The evaluations were carried out 365 days after planting, when the growth, production components and technological attributes of the sugarcane were evaluated. Vertical planting provides greater plant height, number of photosynthetically active leaves, number of dry leaves, number of internodes, stem diameter, leaf area, production and TCH. Conventional planting provides greater ATR, total soluble solids, sugarcane pol, juice pol and fiber percentage. The other industrial variables were not influenced by the planting system.
