Aclimatación de cinco cultivares de cebolla colorada (Allium cepa L.) a campo abierto

Abstract

This research proposes to evaluate the acclimation of 5 cultivars of red onion (Allium cepa L.) open field, in Riobamba City, Chimborazo Province. For the statistical design ADEVA was used of Design Complete Block design (RCBD), five experimental units were established, three replications.

Among the five cultivars used in this study, there were differences found in the majority of analyzed variables; Thus agronomically cultivar with highest percentage of emercency was Red Snack (V3) with 96,06%, cultivar with best prendimiento was Bourgeois (V5) with 98,52%, to the height of the plant there was no major difference; the greatest number of leaves reached Super Red (V1) 10,60 leaves; the largest pseudostem diameter was reached by Super Network (V1) with a value of 2,08 cm., most cultivars late werw Super Red (V1) and Red Snack (V3) with 150 days, the greater weight of the bulb in the three categories and the best firmness of bulb obtained in the cultivar Bourgeois (V5).

The best performance presented the cultivar Bourgeois (V5) with a value of 33,14 tm/ha. Economically, the cultivar that you presented lower variable cost was the cultivar Red Snack (V3) with 2622,81 USD, while to the cultivar Bourgeois (V5) presented a higher variable cost with 4718,02 USD. The greatest cost benefit obtained cultivar Francisca (V4) with 2,55 wich gives us a return of 155%.

KEY WORDS: Agronomic Evaluation, Acclimation of Cultivating, Grow Onion, Agronomic Performance, Economic Profitability.
