    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.
