Resumo
A rotação de cultura é uma pratica de campo usadas já a muitas décadas na agricultura, trazendo grandes resultados em manejo e produtividade. O sul de Santa Catarina tradicionalmente é um grande e reconhecido produtor de arroz, mas com um setor que vem sofrendo uma crise econômica já a alguns anos, com queda significativa de qualidade e produtividade. Um responsável direto por essa crise, são as ervas daninhas, como o capim arroz e o arroz vermelho, comprometendo os resultados financeiros em toda a região. Nos últimos anos com a demanda crescente de grão no planeta e o uso de técnicas de rotação de cultura, a Região sul despertou para a produção de grãos como a soja, para isso técnicas tem sido estudadas e implementadas em toda região. O objetivo do presente trabalho é substituir o cultivo de arroz pela soja na região de Içara (SC), visando adaptabilidade de sete cultivares, produtividade, além da redução da população das ervas daninhas presentes. Para obtenção de produtividades elevadas o manejo do solo, lençol freático, correção e adubação deve ser realizado criteriosamente dentro das técnicas agronômicas recomendadas. A variedade 592 soytech se destacou com produtividade de 54 sacas por hectare, mas ainda, a zeus brasmex e 6070 soytech merecem que produziram 35 sacas por hectare merecem novos estudos, já que o clima foi bastante severo durante o ciclo 2021/2022, com estiagem nas fases iniciais do ciclo, elevadas temperaturas na período reprodutivo e excesso de chuvas na colheita. Ficou evidente ainda a redução na população de capim arroz e arroz vermelho. Novos estudos devem ser realizados para as melhorias nas técnicas de manejo e adequação de população de plantio, visando incremento de produtividade.
Crop rotation is a field practice used for many decades in agriculture, bringing great results in management and productivity. The south of Santa Catarina is traditionally a large and recognized producer of rice, but with a sector that has been suffering an economic crisis for some years, with a significant drop in quality and productivity. Directly responsible for this crisis are weeds, such as rice grass and red rice, compromising financial results throughout the region. In recent years, with the growing demand for grain on the planet and the use of crop rotation techniques, the southern region has awakened to the production of grains such as soybeans, for which techniques have been studied and implemented throughout the region. The objective of the present work is to replace rice cultivation with soybean in the region of Içara (SC), aiming at adaptability of seven cultivars, productivity, in addition to reducing the population of weeds present. To obtain high yields, soil management, water table, correction and fertilization must be carried out judiciously within the recommended agronomic techniques. The 592 soytech variety stood out with a productivity of 54 bags per hectare, but still, the zeus brasmex and 6070 soytech deserve that they produced 35 bags per hectare deserve further studies, since the climate was quite severe during the 2021/2022 cycle, with drought in the initial phases of the cycle, high temperatures in the reproductive period and excessive rainfall at harvest. It was also evident the reduction in the population of rice grass and red rice. New studies must be carried out for improvements in management techniques and adaptation of the planting population, aiming at increasing productivity.
