Abstract


The aim of the present work was to evaluate the effect of phosphorus and potassium fertilization on the production and the quality of pigeon pea seeds produced on a ferrasol type sol. A completely randomized block design was used, in a 2x3x3 factorial set with three replications. A density of 20 000 plants ha -1 was used. The treatments were 0, 40, 80, units for phosphorus (P2O5) and potassium (KCl). Treatment which received P80K80 fertilization had greater productivity (650 kg) but a low germination rate (30 %). The optimal dose (523 kg and 90 % germination rate) was obtained with P40K80, followed by P40K40 dose (516 kg and 82 % germination rate). Phosphorus and potassium had mutually acted and influenced positively the production and the quality of the seeds of C. cajan.
