New sugarcane varieties attract interest from producers

Faced with the need to increase productivity, an increasingly large group of sugarcane producers is looking for new varieties that can achieve greater longevity and greater ability to adapt to weather and soil conditions.

In the second half of September, producers had the opportunity to get to know five of these new varieties, launched by the Agronomic Institute (IAC) and which were presented at the IAC Varietal Garden by Marcos Guimarães de Andrade Landell, leader of the Cana IAC Program and general director d

the IAC and by the researcher Mauro Alexandre Xavier.

On the occasion, the varieties IACCTC07-7207, IACSP02-1064, IACCTC05-5579, IACCTC06-5732, and IACCTC08-9052 were presented. According to the IAC, these new materials have a superiority of 12 to 27% in relation to the standard variety observed in the studies, considering productivity and longevity. and adaptation to different sugarcane regions in Brazil and different types of soils.

Producer Renato Trevizoli, who works in an area of ​​500 hectares, in the municipality of Taquaritinga, highlights the importance of searching for new varieties, which must be accompanied by a constant evolution in management.

“We have an idea of ​​always working with new materials, to have this genetic gain, with a larger population of stems, and a better response in productivity. But we know that if a material has a larger population of stems, it cannot be treated in the same way as material that was released in the 80's. So the phytotechnical management has to follow. We have to provide adequate nutrition, water management of the matrix of the third axis, so that it (the new variety) can express its genetic potential”, he said.

For the Agricultural Manager of Grupo Aralco, Dioni Satin, “the visit was intended to get to know the projects and programs, to be closer to the IAC and to bring new technologies to the company, as well as news of promising varieties. It was a very pleasant and productive junction”, he said.

Satin was accompanied by the plant's Preparation, Planting and Cultural Care coordinators, Thiago Cavalini and Rodrigo Sirotto.

“Our objective is productivity and longevity of the cane fields. We are working with productivity above the triple digits. We were already doing the physical and chemical part and what we lacked was the biological part. We seek to bring back the health of this soil that is losing quality over the years”, explains the producer.

The farmer, in addition to standard chemical and physical analyses, invested in enzymatic and DNA analyses, which are more complex biological analyzes that identify which individuals are acting in the soil.

“We did profile analyses, reaching 60 cm and several comparisons between the samples. They are organisms invisible to the naked eye, but they are fundamental. In the first analyzes we identified a better phosphorus index and in beta-glucosidase it showed an increase in the organic matter and carbon content, which improves the soil profile”, explained Delarco.

“We chose to carry out all treatments located in the planting line, with the objective of correcting the soil profile from 0 to 60 cm in depth, thus creating conditions for the cane field to develop in this region and taking its root system to a greater depth. Thus, suffering less from water stress, with greater exploitation of water, fertilizers and organominerals, and the results are impressive”, says the producer.
