Obtaining quality seed is conditioned by several factors such as the nutritional status of the parent plant, the time of harvesting the seed and the processing (drying). Therefore, the objective of this work was to evaluate whether pod harvests and seed drying influenced the storage time and physiological quality of the bean seeds. Objective II: To evaluate if P influences the physiological quality of bean seeds. Objective III: To evaluate the growth and progression of nutrient absorption during the crop cycle. The highest germination results (87%) were obtained at the harvest time of the pods at 15 DAA when the seeds remained dry inside the pods. When the seeds dried out from the pod the most indicated is to harvest at 14 DAA (84%). Storage should be carried out up to 6 months when they are dried out of the pod. In the drying mode of the seeds that remain in the pod, the maximum storage time is up to 12 months. In relation to the nutritional status of the plant, the different doses of P, influenced the growth, the absorption, the production and the physiological quality of the seeds. The dose of 1.5 mmol L-?? was indicated by the quadratic adjustment model as the dose of maximum economic efficiency. The critical level of deficiency and toxicity at 35 DAE (time of nutritional diagnosis) was 6.9 to 8.4 g kg-??, and at 60 DAE (end of the experiment) it was 10.7 to 13.3 g kg-??, respectively. Three different phases of vegetative growth (0 to 30 DAE), reproductive phase (31 to 60 DAE) and senescence (61 to 80 DAE) were also identified for the bean plants. The sigmoidal equation is the model that best represented the growth curve of the plants. The nutritional management of the crop should be carried out up to 45 DAE. The order of total extraction of macronutrients by the plant at the end of the cycle was Ca> K> N> P> S = Mg and of micronutrients Fe> B> Mn> Zn> Cu. O rendimento da cultura do feij??o-de-metro est?? ligado ?? sementes de alta qualidade fisiol??gica, que por sua vez, ?? a express??o do m??ximo poder germinativo e vigor. A obten????o de sementes com qualidade ?? condicionada h?? diversos fatores tais como, o estado nutricional da planta-m??e, a ??poca da colheita da semente e o beneficiamento (secagem). Portanto, este trabalho teve como objetivo I: Avaliar se a colheita das vagens e a secagem das sementes influencia no tempo de armazenamento e na qualidade fisiol??gicas das sementes de feij??o-demetro. Objetivo II: Avaliar se o P influ??ncia na qualidade fisiol??gica de sementes de feij??o-demetro. Objetivo III: Avaliar o crescimento e a marcha de absor????o de nutrientes durante o ciclo da cultura. Os maiores resultados de germina????o (87%) foram obtidos na ??poca de colheita das vagens aos 15 DAA quando as sementes permaneceram secando dentro das vagens. Quando as sementes secaram fora da vagem o mais indicado ?? colher aos 14 DAA (84%). O armazenamento deve ser realizado at?? 6 meses quando forem secas fora da vagem. No modo de secagem das sementes que permanecem na vagem, o tempo m??ximo de armazenamento ?? at?? 12 meses. Em rela????o ao estado nutricional da planta, as diferentes doses de P, influenciaram no crescimento, na absor????o, na produ????o e na qualidade fisiol??gica das sementes. A dose de 1,5 mmol L-?? foi indicado atrav??s do modelo de ajuste quadr??tico como a dose de m??xima efici??ncia econ??mica. O n??vel cr??tico de defici??ncia e de toxidez aos 35 DAE (??poca da diagnose nutricional) foi de 6,9 e 8,4 g kg??, e aos 60 DAE (final do experimento) foi de 10,7 a 13,3 g kg- ??, respectivamente. Foi identificado tamb??m, para as plantas de feij??o-de-metro tr??s fases distintas de crescimento vegetativa (0 a 30 DAE), fase reprodutiva (31 a 60 DAE) e senesc??ncia (61 a 80 DAE). A equa????o sigmoidal ?? o modelo que melhor representou a curva de crescimento das plantas. O manejo nutricional da cultura deve ser realizado at?? os 45 DAE. A ordem da extra????o total de macronutrientes pela planta no final do ciclo foi de Ca>K>N>P>S=Mg e de micronutrientes foi Fe>B>Mn>Zn>Cu.
