Performance of the snap bean (Phaseolus vulgaris L.) with traditional fertilizations vs. technical fertilization. The experiment was made in the farm called El Ancon - Pradera, (Cauca, Valle), with 1100 mm of precipitation, 940 m.a.s.l. 73.5% R.H. and a temperature of 24°C. In order to get basic information, a completely randomized block design was installed with three replications and eight treatments (control, T-traditional, T-10B-Urea, T-10B-S ammonium, T-05B-Urea, T-05B-S.Anunonium, T-10B-U.SA, T-05B-U.SA). Variables measured were dry matter weight (DNV) (at 15-30-45) leaf area (L.A) (at 15-30-45) and production (50-70d). Treatments with best productions mean values were: T-I0B-Urea, T-IOB-U.SA, T10B-S. Anunonium, T-05B-S.Anunonium with 8067.0, 6928.4 and 6194.4/ha respe., all of them above the average of the trial. High investment T-traditional do not have a similar answer in relation to their productions, but the T-I0B-Urea treatment has a lower cost and rentability of 84.46%.
