Castor bean is a nutrient-demanding species, but there is still little information on its micronutrient requirements. The objectives of this study were to evaluate the effects of levels of B (2.5, 12.5 and 25.0 µmol L-1), Cu (0.05, 0.25 and 0.50 µm

A toxidez de Mn pode ser um problema comum nas regiões tropicais com predominância de solos ácidos. Entretanto, variações das concentrações desse nutriente nas plantas têm sido atribuídas também a diferenças inter e intra-específicas. O p
