Respuesta del cultivo de hortalizas a diferentes tipos de aplicación de nitrógeno en la granja Santa Inés

Abstract

Urea is an efficient resource characterized by its high content of ammoniacal nitrogen (NH4) available in the soil solution. The study was carried out in the Machala canton, province of El Oro, in the plots of the experimental area of the Santa Inés Farm, and is based on the dosage of nitrogen fertilizer (Urea), the Completely Random Block Design was used. . The objective of the study was to determine the influence of different doses of nitrogen application on the El Salvador pepper crop. Five doses of N were evaluated (0-50-100-150-200 kg/N/ha) carrying out four evaluations every 15 days from transplant in the field, culminating in a cycle of 80 days until harvest. The following variables were assessed: Plant height, stem diameter, number of leaves, number of fruits, fruit weight, agricultural yield. T4 (200 kg/N/ha) showed greater efficiency in each variable followed closely by T2 (100 kg/N/ha) starting at 30 DAT, reaching harvest after 80 days, a period in which the Demand for nutrients increases progressively due to the precocity of the crop, which can make it a suitable hybrid for the coastal region of Ecuador.
