Efecto de dosis creciente de nitrógeno en la producción de pepino híbrido.

Abstract

The study was conducted at the "The Mouth" Farm located in the Palmales-Arenillas, El Oro, Ecuador, with the aim of determining the effect of different nitrogen doses on the cucumber crop (Cucumis sativus, L) hybrid Humacro, focusing on the yield and profitability of the crop. The experimental design was a Completely Randomized Block Design (CRBD), with replicated plots to minimize variability, employing 5 treatments with recommended doses (T1: 25% RD; T2: 50% RD; T3: 75% RD; T4: 100% RD; T5: 125% RD) and 1 control treatment (T6: 0% RD). Field materials and tools were used for planting, maintenance, and harvesting of the crop, as well as laboratory instruments for measuring the established parameters. The variables to be evaluated included weight (g), diameter (mm), length (cm), quality, and production (t/ha) of the fruit. Among the results, treatment T5 showed the best outcomes in the fruit weight variable (489.82 grams), while treatments T4 and T5 exhibited lengths and diameters reaching 23.47 cm and 23.05 cm, and 59.22 mm and 58.96 mm, respectively. Regarding fruit quality, all treatments were statistically homogeneous, again highlighting the mentioned treatments; in terms of productivity, no treatment exceeded the established level for estimating nutritional requirements (100 t/ha), but there were values that approached this figure, particularly emphasizing treatments T4 and T5. In conclusion, the information provided in this study on the influence of increasing nitrogen doses can contribute to improving agricultural practices and productivity in cucumber cultivation.
