M.  aEfeitos da leucena e da adubação NPK sobre a cultura do feijão no cerrado.h[electronic resource]  c1983  aAn experiment was carried out in a poor cerrado soil at Patrocinio, state of Minas Gerais, in order to determine the effect of Leucaena leucocphala, as a green manure, and chemical fertilization on the yield of beans (Phaseolus vulgaris). Treatments included leucena plus a 2 x 2 x 2 factorial, as levels of 0 and 40kg/ha of N (as ammonium sulfate), 0 and 70kg/ha of P2O5 (as ordinary super-phosphate), and 0 and 60 kg/ha of K2O (as potassium chloride). Additional treatments were 0-0-0 and 40-70-60- kg/ha of N-P2O5-k2O, both without the green manure. The leucena and the NPK fertilization had the same effect, increasing the bean yield from 83 to 350 kg/ha. With leucena, the superphosphate had the greatest effect, followed by the nitrogenous fertilizer. The complete chemical fertilization associated with the green manuring resulted in the hihest yield of 900 kg/ha.  anitrogen  aphosphorus  apotassium  aAdubação Verde  aCerrado  aFeijão  aFósforo  aLeucaena Leucocephala  aNitrogênio  aNpk  aPhaseolus Vulgaris  aPotássio  aFertilizacao  aFertilization  aGreen manure  aLeucena  aMinas Gerais  aPatrocinio  aSavanna1 aPEREIRA FILHO, I.
