Resumo: | The objectives of this work were to adjust nonlinear regression models for the green beans production and to identify the plot size which provides the best explanation and adjustment to the models. The authors used two field and two protected environment (plastic tunnel) trials in the autumn-winter and spring-summer seasons. The logistic and von Bertalanffy models were adjusted for average weight of green beans accumulated after multiple harvests and with different plot sizes. The models presented similar estimates and the same parameters estimates in all the plot sizes. The logistic model provided estimates closest to the reality, showing the best description performance for the average weight of pods during the productive cycle. In the autumn-winter season, plot size of 14 basic units (28 plants in the cultivation line direction) in the field and of two basic units (four plants in the cultivation line direction) under the plastic tunnel provide a good quality in the models adjustment. In the springsummer season, the plot sizes are made of six basic units (12 plants in the cultivation line) in the field and seven basic units (14 plants in the cultivation line) under the plastic tunnel. |

Foram utilizados dois ensaios a campo e dois em túnel plástico, realizados nas estações outono-inverno e primavera-verão. Os modelos ajustados foram o logístico e o de von Bertalanffy, para peso médio de vagens acumulado nas múltiplas colheitas e com diferentes tamanhos de parcela. Os modelos apresentaram estimativas semelhantes entre sí e as mesmas estimativas dos parâmetros em todas os casos de tamanho de parcela. O modelo logístico proporcionou estimativas mais próximas da realidade, apresentando melhor desempenho na descrição do comportamento do peso médio de vagens no decorrer do ciclo produtivo da cultura. Na estação sazonal outono-inverno parcelas de 14 UBs (28 plantas no sentido da linha de cultivo) a campo e de duas UBs (quatro plantas no sentido da linha de cultivo) em túnel plástico proporcionam uma boa qualidade no ajuste dos modelos. Na estação sazonal primavera-verão os tamanhos de parcela são de seis UBs (12 plantas no sentido da linha de cultivo) a campo e de sete UBs (14 plantas no sentido da linha de cultivo) em túnel plástico.The authors thank CAPES (Coordination of Improvement of Higher Education Personnel) for PhD scholarship, abroad, granted, process no BEX 1457/14-4.Associação Brasileira de HorticulturaBiblioteca Digital do IPBLúcio, Alessandro D.Nunes, LuísRego, Francisco2017-01-11T14:59:06Z20162016-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10198/13726engLúcio, Alessandro D.; Nunes, Luís; Rego, Francisco (2016).
