    Equilibrio catiónico en la productividad del cultivo de tomate de árbol (Solanum betaceum Cav.) variedad amarillo gigante
    (2023-12) Morocho Quishpi, María Manuela; Guerrero Cando, David Aníbal
    The cultivation of tree tomato (Solanum betaceum) in Ecuador energizes the local economy of small and medium producers in the provinces of Carchi, Imbabura, Cotopaxi, Tungurahua and Chimborazo, however, poor nutritional management results in a considerable reduction of productivity and quality of the fruit. In the El Altar parish, Penipe, the productive response of the tree tomato (Solanum betaceum Cav) giant yellow variety to the application of three cationic balances T1 (55% Ca, 20% K, 25 Mg), T2 (60%) was determined. Ca, 30%K, 10%Mg), T3 (80% Ca, 15%K, 5%Mg). Different variables were evaluated, such as fruit weight and diameter, number of fruit plant-1, plant yield-1, yield ha-1. and % dry matter. The results demonstrated that there is a positive relationship between the cationic balance doses on the yield of tree tomato (Solanum betaceum Cav). In particular, the T2 treatment of cationic balance (60% Ca, 30% K, 10% Mg) is the one that presented the best response for the agronomic variables under study with a productivity of 44 Tn. ha-1. All treatments evaluated, including the absolute control, were profitable because the benefit-cost ratio was greater than unity. However, the highest level of profitability was achieved with the use of the cationic balance (60% Ca, 30% K, 10% Mg) with a value of 2,9 In short, the study shows that the optimal balance of cations (Ca2+, Mg2+, K+) in the soil can significantly improve the productivity and profitability of tree tomato cultivation.
