Calibración de la dosis de nitrógeno mediante dos abonos orgánicos y el nitrato de calcio utilizando el cultivo de pimiento (Capsicum annuum L.).

Abstract

The objective of this research work was to calibrate the nitrogen dosage through two organic fertilizers and calcium nitrate using the bell pepper crop (Capsicum annuum L.). The experimental research was conducted using a bifactorial randomized block design in divided plots, with ten treatments and three replications, considering as treatments two organic fertilizers (humus and ecoabonaza), a synthetic fertilizer (calcium nitrate), and absolute control at different dosages of 75, 150, and 225Kg N/ha. The following parameters were evaluated the percentage of apprehension, days to flowering, the number of fruits/plants, fruit length, fruit diameter, fruit weight in grams/plant, yield per hectare in Kg/ha, replacement value, fertilizer use efficiency, and economic analysis through benefit-cost ratio. In agronomic behavior, there was a significant difference between treatments, except for the percentage of apprehension, where there were no significant differences, with earthworm humus being the fertilizer that presented the best characteristics. In the replacement value of the fertilizer, it was showed that the earthworm humus had a high efficiency of 47.32% to that of calcium nitrate. In terms of yield, it was determined that earthworm humus at a dose of 225 Kg N/ha presented the best yield with 6252.78 Kg/ha. About the cost-benefit ratio. The treatment that showed the highest Benefit/Cost was the earthworm humus at a dose of 225 Kg N/ha with a profit of 41 cents. The application of earthworm humus at a dose of 225 Kg N/ha is recommended to obtain a higher agronomic and economic yield.
