Abstract: RESUMOEste estudo teve como objetivo ajustar modelos de crescimento ao acúmulo de matéria seca da parte aérea da cana-de-açúcar durante o período de formação da cultura, para as cultivares RB92579, RB867515, RB928064 e RB855453. Dados de matéria seca foram obtidos durante a execução de experimento em condições de campo entre 26/08/11 e 18/05/12. Os dados experimentais foram coletados a partir dos 45 dias após o plantio, em intervalos de uma ou duas semanas, totalizando 17 datas de amostragem. Os valores obtido… Show more

“…Its application has been extended to studies on nutrient uptake and utilization based on data from nutrient accumulation at different crop stages (Araújo and Rossiello, 2013). Growth analysis in sugarcane is a tool for assessing the sequential dry matter accumulation and nutrients and relate them to environmental parameters such as irradiance, water availability, soil fertility, among others (Santos et al, 2009;Silva et al, 2012;Batista, 2013).…”

“…Thus, the integration of two or more models aims to obtain a more efficient model for the prediction of agricultural crops [42]. Reference [43] combined the expolinear-logistic model and the Gompertz model to estimate the variation of shoot dry matter accumulation in sugarcane cultivars. Reference [42] combined models of Fuzzy Logic and Neural Networks to estimate wheat productivity as a function of nitrogen fertilization.…”

“…Analisando a relação fonte nitrogenada x cultivar (Figura 2 C), a cultivar SP 803280, obteve queda na altura iniciada no 160° dia em relação à RB 867515, sendo evidente para o biofertilizante. Batista et al (2013) conduziram um experimento por 230 dias, visando avaliar a modelagem do crescimento de cultivares de cana-de-açúcar no período de formação da cultura. Os autores utilizaram as variedades RB 92579, RB 867515, RB 928064 e RB 855453, com uso de adubação no plantio, por meio de 45 kg ha -1 de N, 120 kg ha -1 de P 2 O 5 e 45 kg ha -1 de K 2 O, aplicados nos sulcos e realizando adubação de cobertura aos 60 dias após o plantio com 45 kg ha -1 de N e 45 kg ha -1 de K 2 O nas linhas das plantas.…”
