Resumo: Growth and solar energy conversion in common bean (Phaseolus vulgaris L.) cv. Negrito 897 grown under three nitrogen levels (50, 125 and 200 ppm of N) ad two water systems (field capacity and cyclic water stress from -0.03 to - 1.0 MPa) were studied in the greenhouse; The water system showed greater effect on growth than nitrogen levels, though high nitrogen level minimized the hydric stress effects, producing plant hardening by increment in the root development. The water deficit reduced and high nitrogen level increased the efficiency of solar energy conversion.

C.V. Negrito 897, adubado com três doses de nitrogênio (50, 125 e 200 ppm de N) e submetido a dois regimes hídricos (Capacidade de campo e estresse hídrico cíclico de -0,03 a -1,0 MPa). O regime hídrico apresentou maior efeito no crescimento do que as doses de N, embora a dose elevada desse elemento tenha minimizado o efeito do déficit hídrico, provocando maior endurecimento dessas plantas, causado pelo maior desenvolvimento das raízes. O déficit hídrico reduziu e o incremento da dose de N aumentou a eficiência de conversão de energia solar.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCosta, Roberto C.
