Resumo: Sugarcane crops are grown in almost all regions of Brazil, in various types of soil and under the influence of different climate conditions, which results in diverse production environments as climate factors directly influence the yield and technological quality of a sugarcane crop. The present study evaluated the agronomic and technological characteristics of sugarcane cultivars grown in Af climate conditions. The agronomic traits (natural matter production and the number, length, and diameter of stalks) and technological attributes (Brix, purity, Pol, reducing sugars, total reducing sugars, moisture, and fiber content) of three sugarcane cultivars, IACSP93-6006, RB83-5486, and SP79-1011, were determined in a three-year experiment with a randomized block design using four blocks and two repetitions per block. The cultivars IACSP93-6006 and SP79-1011 exhibited superior agronomic traits compared to RB83-5486, showing better adaptation to the soil and climate conditions of the study area. However, the technological attributes, which were below the minimum standard levels required by the sugar and ethanol industry, were not statistically different among the studied cultivars. The abundant rainfall and high temperatures, characteristics of an Af climate, were not favorable for sucrose accumulation in the IACSP93-6006, RB83-5486, and SP79-1011 cultivars. Therefore, despite the high yield, sugarcane intended for industrial purposes should not be grown under Af climate conditions, owing to the insufficient technological parameters.

Objetivou-se avaliar as características agronômicas e tecnológicas de cultivares de cana-de-açúcar cultivadas em condições climáticas tipo Af. Foram utilizadas três cultivares de cana-de-açúcar: IACSP93-6006, RB83-5486 e SP79-1011. O experimento foi realizado em delineamento em blocos casualizados, com quatro blocos e duas repetições por bloco. Na avaliação agronômica foram determinados a produção de matéria natural, número de colmos, comprimento do colmo e o diâmetro do colmo. Quanto aos atributos tecnológicos foram determinados Brix, pureza, Pol, açúcares redutores, açúcares redutores totais, umidade e fibra. Houve diferença para as características agronômicas, produção de matéria natural, número de colmos, comprimento do colmo e diâmetro do colmo, com destaque para as cultivares IACSP93-6006 e SP79-1011, que demonstraram adaptação às condições edafoclimáticas da região. Não houve diferença para os atributos tecnológicos, Pol, Brix, açúcares redutores, pureza, açúcares redutores totais, fibra e umidade, cujos valores ficaram abaixo do padrão mínimo exigido pela indústria de produção de açúcar e álcool, evidenciando que as condições climáticas não foram favoráveis ao acúmulo de sacarose, pois no clima tipo Af a precipitação pluviométrica e temperatura são elevadas. As cultivares apresentaram altas produções por hectare, no entanto, os parâmetros tecnológicos foram insuficientes para serem usados na indústria sucroalcooleira.UEL2020-01-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de CampoPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3637710.5433/1679-0359.2020v41n1p73Semina: Ciências Agrárias; Vol. 41 No. 1 (2020); 73-82Semina: Ciências Agrárias; v. 41 n. 1 (2020); 73-821679-03591676-546Xreponame:Semina.
