Over a two year period, the effect of fertilization on the growth of native leguminouses under grazing was studied. Treatment were 0, 30, 60 and 90 kg of P2O5/hectare/year in combination with KCL (75 kg of K2O/hectare/year) and without KCL, with and without agricultural lime (2.5 ton/hectare/year). Treatments were applied on previously established Faragua pastures. Leguminous counts were done at 6, 12, 18, 24 and 30 months, taking note on each occasion of the population per square meter per treatment. Significative differences were found (P<.05) between treatments. Using K2O and lime, the average leguminous production of the three phosphatised treatments did not differ from the average of the witness treatment, while in presence of K2O without agricultural lime, without K2O with agricultural lime, and without K2O and agricultural lime, the average of the phosphatised treatments were significantly greater (P<.05) than the average of witnesses treatments. Higher population of leguminouses were obtained by the use of phosphatised treatments + agricultural lime without K2O; while smaller production was show using phosphatised treatments + K2O without agricultural lime, without K2O and agricultural lime. Levels of 60 and 90 kg of P2O5/hectare/year + agricultural lime with no K2O, gave higher leguminous production.
