Abstract


This study was to evaluate the nutrition and the agronomic part of bean intercropped with castor crops submitted to sources and levels of B in the Anápolis-GO, Brazil. The treatments consisted of two sources of B (borax = 11% B and boric acid = 17% B) combined with five levels of B (0.0, 0.5, 1.0, 2.0 and 4.0 kg ha-1 in soil) in bean intercropped with castor, plus monoculture, using 1.0 kg ha-1 B. That leaf levels of B and S in beans, and of B, N, Ca, Mg and Fe in castor were influenced by the sources and levels of B in the intercropping. The bean yield intercropped with castor was not influenced by borated fertilization, neither by the interaction of factors. The highest yield of castor intercropped with beans, 2.040 kg of grains ha-1, was obtained with the 1.9 kg ha-1 of B, regardless of the source used.
