Effect of phosphorus fertilization on potato yield and nutrient absorption in andisol from Juan Viñas, Costa Rica description

The response of the potato crop to phosphoric fertilization in a Hydric Hapludands soil from Hacienda Juan Viñas was studied. 0, 150, 300, 450 and 600 kg.ha-1 of P2O5 were applied for 1 and 2 consecutive years. Foliar samples were taken at flowering time (48 dds), aerial biomass before foliage burning (93 dds) and tubers at harvest time (116 dds). Tissue samples were measured fresh and dry weight and chemical analysis was performed for N, P, Ca, Mg, K, Mn, Zn, Cu, Fe, S and B. By applying P only the first year of the experiment, the yield of the culture was inferior and no residual effect was appreciated with any of the doses. With the consecutive application of P for 2 years, the crop responded in an increasing way to the increase in the dose of fertilizer, reaching the maximum yield of tubers (16.39 t.ha-1) with 600 kg.ha-1 of P2O5.
