Abstract

Distinct varietal differences in yield and other agronomic characteristics among the eleven varieties were observed when planted at monthly intervals for a period of one year.

White Portugal had the tallest and heaviest green tops yield when planted in December. It had also the greatest diameter and length of leaves in December and February planting while it was second in the January planting.

Southport white Globe was the tallest with the greatest diameter and length of leaves when planted in January. Its polar diameter of bulb was also greatest when planted in March.

Excel X17014 had the greatest equatorial diameter of the bulb in the December and January planting and had the greatest polar diameter and number of marketable bulbs when planted in January.

Grano 502 produced the greatest number of marketable bulbs when planted in December.

Red Wethersfiled was the greatest in polar diameter of bulb when planted in March.

Granex performed will in equatorial diameter of bulb and number of marketable bulbs (with tops) produced when planted in February.

Nebuka, a bunching onion, was best in weight of green top yield in February number of green tops in April, leaf diameter in May and June; and plant height and length of leaf in June.
