Atributos químicos do solo e produção do feijoeiro com a aplicação de calcário e manganês

摘要: Common bean is one of the most important staples in Brazil. The objective this study was to evaluate common cv. Perola yield and changes soil chemical attributes as influenced by liming manganese rates. experiment carried out pots containing dystrophic Red Yellow Latosol (Oxisol). Treatments consisted a 2 x 6 factorial combination two limestone (CO3 MgCO3 3:1 molar ratio) rates, calculated increase base saturation 50 70 %, respectively, six Mn rates (0, 20, 40, 60, 80 100 mg kg-1), using MnSO4.H2O source. There were three repetitions. Results showed that higher reduced leaf concentration, but concentration after harvest not altered. sufficient reach maximum grain similar for both % saturation, doses such critical 28 57 dm-3, respectively.
