Production of cucumber cultivars according to the accumulated thermal sum

Cucumber is a species appreciated in cooking, addition to providing various nutrients for health. In view of this, it important that research on its growth carried out, prioritizing statistical analyzes effectively demonstrate the results. The objective was verify differences by analyzing variance and nonlinear models, characterizing production, early production rate cultivars cucumber using models. An experiment out randomized block design (RBD), with three (‘Atlantico’, ‘Caipira’ ‘Fuyu’) six replications. Two types analysis were performed variable mass fruits. first RBD considered replications second split subdivided over time (cultivars x harvests). Afterwards, Logistic model adjusted fruit as function accumulated thermal sum, determination critical points model. use models evaluate experiments cultures multiple harvests has advantages relation anova complementary tests. cultivar ‘Fuyu’, higher productivity compared ‘Atlantico’ ‘Caipira’, presenting greater precocity rate. adjustment logistic allowed identify evaluated cucumber.
