This research aimed to evaluate the effect of planting density and complementary irrigation on the morpho-phenology, yield, profitability, and efficiency of banana fertilization in the Carrizal River Valley, Ecuador. The treatments consisted of two production systems (irrigation and rainfed) and four planting densities (1500, 2000, 2500 and 3000 plants ha-1). The variables recorded were bunch weight (kg), fruit yield (boxes ha-1), net economic benefit (USD ha-1) and NPK agronomic efficiency. Supplementary irrigation increased production by 30%, compared to the rainfed system. The bunch weight was inversely proportional to the crop densities, while the fruit yield was proportional to the densities. The linear regression model showed an increase of 6.50 kg of fruit plant-1 with supplementary irrigation, while in rainfed the production was 4.99 kg of fruit plant-1, signaling a loss of 1.51 ...

El objetivo de la investigación fue evaluar el efecto de aplicaciones foliares complementarias de Zn y Mo sobre el rendimiento, rentabilidad y eficiencia agronómica del nitrógeno en maíz de secano. El trabajo se desarrolló durante las temporadas lluviosas 2020 y 2021, en el valle del río Carrizal, Manabí, Ecuador. Los tratamientos evaluados fueron: Fertilización edáfica NPK complementada con aplicación foliar de Zn y Mo (T1), y fertilización edáfica NPK sin aplicación foliar de Zn y Mo (T2). Se registró el rendimiento de grano (RG), eficiencia agronómica de N (EAN) y el beneficio económico neto de la fertilización (BEN). Los datos fueron analizados con prueba estadística de t de Student para observaciones pareadas. El tratamiento T1 aumentó el RG en 15,58% y 14,03% durante el 2020 y 2021, respectivamente, con respeto al tratamiento T2. Del mismo modo, el tratamiento T1...
