Present work had the goal to evaluate the effects of five doses of phosphorus and four of potassium in two plant inter-row spacing on seeds and biomass yield of short-cycle late sowed pigeonpea. This work was developed in Selvíria, State of Mato Grosso do Sul, with sowing in January of 2005. Experimental design was a 2 x 5 x 4 factorial in completely randomized block design, with four replications. Treatments were 30 and 50 cm plant spacings inter-row spacing, 0, 40, 80, 120 and 160 kg ha-1 of P2O5 and 0, 30, 60 and 90 kg ha-1 of K2O. Seed yield was greater with 30 cm plant spacing and biomass yield and plant height with 50 cm plant spacing. Phosphorus and potassium fertilizer use did have a positive effect, mainly with doses around 120 kg ha-1 dose of P2O5 and 60 kg ha-1 of K2O.
