Production and Quality Of Tomatoes For Different Relations K:Ca:Mg In The Nutriente Solution.

Among the various existing types of tomatoes, mini-tomatoes has stood out due to their characteristics, as well as being very attractive and tasty, has high added value encouraging producers to invest in the cultivation of this vegetable. However, there is lack of information regarding the composition and management of nutrient solution to obtain greater productivity and fruit quality. Therefore, the aim of this study was to determine the production of two cultivars of mini-tomato under different relations K: Ca: Mg in the nutrient solution. The experimental design was a randomized block, split plot with four replications and twelve treatments, consisting of the following relations K: Ca: Mg (4:3:1, 6:3:1; 6:4,5:1 , 2,7:3:1; 2,7:2:1; 4:2:1) and two mini-tomato cultivars (Sweet Grape and Sweet Million). The different relations K: Ca: Mg does not influence the production of different cultivars of mini tomatoes grown in substrate, but to grow Sweet Million showed higher yield (1.52 kg plant-1) and higher number of fruits per plant (236) while the Sweet Grape fruit presented with higher weight (8.8 g). Through the analysis of variance was not observed significant differences for the variables, soluble solids, titratable acidity, SS / TA and ascorbic acid. For the variable pH, the highest mean values were observed in relations 4:3:1, 6:3:1, 2,7:2:1 and 4:2:1.
