Efecto de 3 soluciones nutritivas en el cultivo de tomate (Lycopersicum esculententum Mill.), variedad Miramar injerto en briomino, bajo invernadero

Abstract

The objective of this research was to evaluate the effect of three fertigation nutrient solutions on the yield of tomato crops (Lycopersicum esculentum Mill.), var. Miramar graft in briomino, under a greenhouse, in the San Pedro del Quinto sector, Chambo canton, province of Chimborazo. The nutrient solutions were formulated based on a previous soil analysis and a standard solution of H, P, K, Ca, Mg which was increased by 25% and decreased by 25%; in addition to a control to which no fertigation was applied but only foliar fertilization with applications in the same weeks as the rest of the treatments. For the statistical analysis of the variables: plant height, number of fruits per cluster, weight, diameter and color of the fruit and yield, a completely randomized block design (DBCA) with three repetitions was used.Based on the results obtained, it was concluded that nutrient solution 2 generated a higher yield of the tomato crop, followed by nutrient solution 3, both located in range A, according to the Tukey test at 5%. In addition, it was determined that both nutrient solution 2 and nutrient solution 3 obtained the best results when evaluating the number of fruits, weight, diameter and color of the fruit. Finally, it was determined that nutrient solution 2 was the treatment that obtained the highest net benefit and the highest marginal return rate (MRR), being the most economical treatment and the highest yield.
