CONFALONE, Adriana; LIZASO, Jon; RUIZ, Benigno y SAU, Federico. Phenology modeling of faba bean cv. Alameda. Rev. Fac. Cienc. Agrar., Univ. Nac. Cuyo [online]. 2011, vol.43, n.1, pp.75-84. ISSN 1853-8665.
Predicting the phenology of faba bean is a critical step to designing good crop management practices, as well as to the development of crop models. This article examines the phenological response of faba bean (Vicia faba L.) to different temperature and photoperiod regimes assessed through linear models. Seventeen field-sowing dates were used over a three-year lapse in Lugo, Spain (43°04' N, 7°30' W, 480 m altitude), on which phenological observations were made. The time from emergence to flowering was satisfactorily described using a photothermal model, whereas the rates of progress from sowing to flowering, flowering to first pod and first pod to physiological maturity were satisfactorily modeled using only temperature as independent variable. Basal temperature values ranged between 2.09 and 4.47°C, depending on the phenological subperiod. Base photoperiod was 6.9 h, while the critical photoperiod was 16.2 h.
