Efecto de la aplicación de tres niveles de nitrógeno usando tres fuentes de fertilizantes orgánicos en el rendimiento del cultivo de Allium cepa L. grupotysicum cv burguesa (Cebolla colorada).

Abstract

This research titled effect of the application of three nitrogen levels using three sources of organic fertilizers on crop yield of allium cepa l. tysicum cv bourgeois group (red onion), located at the Escuela Superior Politécnica de Chimborazo, using a statistical model of complete random (DCA) blocks, in accordance split plot with nine treatments and three repetitions, for this three fertilizers combined: ferthigue (A1), poultry (A2) and vermicompost (A3) and three nitrogen levels: low (B1), medium (B2) high (B3), corresponding to 75 kg N/ha, 150 kg N/ha and 225 kg N/ha, respectively. Phosphorus and potassium were the same for all levels. With the result that the percentage of engraftment was higher at low levels, the greater plant height was reached with fertigue high level. The largest number of leaves was obtained with fertigue high level and also present more days cosecha.El more leaves was obtained with fertigue high level and also present more days to harvest. Bourgeois variety presents a semi flattened bulb, the highest average bulb weight fertigue I present high level. The highest yield was obtained with high level fertigue 26636.58 kg / ha. The highest net profit was obtained with high manure with $ 7,843.78, the lowest net benefit was obtained with low humus with $ 5,822.87. The highest rate of marginal return is presented in step T5 (chicken medium) to T4 (chicken low) to 454.86%, the application of 225 kg N / ha is recommended as a source of nitrogen and the manure fertilizer for its economic value
