ABSTRACT
Phosphorus is a limiting nutrient in common bean grain yield and may infl uence the chemical composition of seeds.The aim was to assess the effects of phosphorus fertilization and planting dates ('water' and 'dry') 'Carioca Precoce' e 'IAC Carioca Tybatã' were evaluated in growing 'water' and 'drought' in six levels of P 2 O 5 (0, 30, 60, 90, ) applying superphosphate at planting row. It was assessed seed samples to determine the levels of N, P, K, Ca, Mg, S, Cu, Mn, Fe, Zn, total Mn, Fe, Ca, Mg, Cu, total and reducing sugars.
