A field experiment was carried out with the purpose of studying the interrelation between nutrient concentration and the soursop fruit quality. Amounts of K applied were (0, 250, 350, and 450 g.tree-1.year-1). A study was made in Mara municipality belonging to Zulia state which is classified like dry tropical forest, with sandy loam soils, and typic haplargids. A factorial design 4x2 with three replication was used. Following quality parameters were studied: Total soluble solids (TSS), firmness (FIRM) and foliar N, P, K, Ca and Mg contents. Correlation between TSS vs. foliar K (K) and FIRM vs. K were found. There were no correlations between quality parameters and foliar P and Mg concentration and correlation was negative for Ca. The lineal regression between TSS and foliar K for potassium dose and firmness was Y = 11.33 + 3.80 K (r2 = 0.67). The maximum production for “Las Margaritas” farm was found for the leaf K concentration between 1.4 and 1.5 %. The lineal regression for FIRM and K was Y = 0.27 + 0.31 K foliar (r2 = 0.77) for potassium dose and not significative for application date. The K element correlates positive with the TSS and firmness in the soursop fruit. The K foliar induces the quality parameter of the soursop fruit, increasing the firmness and the SST. |
