Evaluación del efecto de n, p2o5, k2o de cuatro formulados inorgánicos en el rendimiento de brócoli (Brassica oleracea l.) var. Avenger, cantón Chilla, provincia El Oro.

Abstract

This present investigation aimed to evaluate the effect of N, P2O5, K2O of four inorganic formulations on the yield of broccoli (Brassica oleracea L.) var. Avenger, Chilla cantón, El Oro province. The treatments evaluated were T1 (120 N, 150 P2O5, 180 K2O kg/ha), T2 (197 N, 135 P2O5, 217 K2O kg/ha), T3 (250 N, 275 P2O5, 121 K2O kg/ha), T4 (280 N, 80 P2O5, 370 K2O kg/ha) and T5 (0 N, 0 P2O5, 0 K2O kg/ha). A randomized complete block design (RCBD) with five treatments and four replications distributed in experimental units of 18m2 that in its interior was delimited a net area of 8m2 in which 10 broccoli plants (Brassica oleracea L.) var. Avenger were randomly selected for data recording; parameters such as: plant height, stem diameter, number of leaves, days to the appearance of the skin and harvest, weight of skin and plant, yield of pellets and harvest residues in kg/8m2 and ton/ha were evaluated, an economic analysis was made using the benefit/cost ratio. The best result was obtained by the application of T3 (250 N, 275 P2O5, 121 K2O kg/ha) that produced 16.99 ton/ha of pellets and a yield of 138.46%. It was concluded that the application of T3 (250 N, 275 P2O5, 121 K2O kg/ha) significantly influences the yield of broccoli (Brassica oleracea L.) var. Avenger so its use is recommended.
