Abstract

In this research is presented the results of the interaction between the bulb diameter and plant density in the production of onion seed variety Caribe-71 throught seed- bulb-seed method in “La Esperanza” from Banao community in Ferralitic Red Leached soil. A design plot in strips with three treatments was used. Bulb were evaluated at 95 days for the number of umbels planted per nest; diameter of the umbel; umbels per meter; flower stalk scape height; flower bulbs amount and rate without umbels drops whilst 1 000 seed weight and the total yield at harvest was determined. The results showed that the number of umbels  and size of them are directly proportional to the bulb size, but the possibility of increasing population density decreases as the bulb is larger, so if we increase it in the same as the bulb is smaller, increase yields. The treatment that used bulbs 3,0 to 4,0 cm of diameter and a density of 24 bulbs per meter exceeded 35 kg ha-1 to treatment of bulbs with larger diameter and in 83 kg ha-1 to treatment of smaller bulb in Banao conditions.
