Abstract

A field experiment was conducted in Rio Verde, State of Goiás, Brazil, with bean (Phaseolus vulgaris L.), Carioca Comum, Rudá, and Pérola cultivars, to evaluate the development of bean cultivars by the establishment of irrigation suppression periods in different growing stages (vegetative, first flowering, full flowering, pod filling, and full maturity), under two depths of fertilizer incorporation (5 cm and 15 cm). The treatments were applied as randomized blocks, with thirty treatments and four repetitions. The root length density was evaluated at 0-10 cm and 10-20 cm. The Carioca Comum cultivar presented higher root length density at 0-10 cm, when fertilizer was incorporated at 15 cm, in all the irrigation suppression periods, except for the pod filling period. The Pérola cultivar presented higher root length density, when fertilizer was incorporated at 15 cm, in all irrigation suppression periods, except for full maturity. The cultivars showed higher root length density in the 0-10 cm sampling layer.
