In order to study the accumulation of the macronutrients by sunflower plants a field experiment was carried out at the "National Center for Soybean Research", Londrina, PR, Brazil. Six fertilizers doses of NPK were used but in the present paper only the dose 0-0-0 was examined. Samples of plants were harvested from 14 days after emergence to the end of the plant cycle. The authors concluded: the maximum accumulation occurs on 73 and 82 days after emergence for leaves and stems, and 90 and 100 days for seeds and receptacle; the maximum accumulation of the macronutrients for a production of 1,000 kg of seeds was K = 131 kg; N = 81 kg; Ca = 60 kg; Mg = 19 kg; P = 13 kg and S = 4 kg; the exportation of the macronutrients correspondent to a production of 1,000 kg of seeds were N = 32 kg; K = 10 kg: P = 6 kg; Mg = 3 kg; Ca = 2 kg and S = 1 kg. |
