Abstract

The field experiment was conducted during the 2006 dry season, in Rio Verde, Goiás State, Brazil. The annual rainfall averages 1400 mm, in two well defined seasons, a dry season (May-October) and a rainy season (November-April), with annual mean temperature between 20°C and 25°C. The development of the common bean (Phaseolus vulgaris L.), Carioca comum, Rudá, and Pérola cultivars, was evaluated, as related to the effects of irrigation suppression periods, in the different stages of plant cycle (vegetative, beginning of flowering, full flowering, developing seed pod, and full maturity), under two depths of fertilizer incorporation (5 cm and 15cm). The experiment was conducted as randomized blocks design, with 30 treatments and four replications. The variables studied were yield (kg ha-1), weight of 100 grains (g), leaf area index (m2 m-2), plant height (cm), number of pods per plant, and number of grains per pod. The irrigation suppression, during the different bean growth stages, was significantly negative in all analyzed varieties, except for weight of 100 grains. The Carioca comum cultivar presented the highest yield, when irrigation was suppressed during the beginning of flowering and full maturity, with fertilizer incorporation at 15 cm. For the Rudá and Pérola cultivars, when irrigation was suppressed in the seed pod development and full maturity stages, the fertilizer incorporation depth did not interfere in the productivity.
