Harvesting a fine crop of Burrell's Yellow Valencia Onions. Note the 
onions in the pile row, the collapsible field crates and in the background 
onions crated and stacked in the field to cure before hauling to storage. 
CULTIVATION 
As soon as the onions are large enough so that the rows can be seen, begin 
cultivating very shallow and as close to the rows as possible without damaging 
the plants. Cultivate every week to ten days until the bulbs have started to 
develop. 
Here a special weeder made from clock spring with handle, is used for re- 
moving grass and weeds from the row (listed page 79). Do not cover the 
onions with soil when hoeing or cultivating. 
If under irrigation; irrigate every week to 10 days until the crop is matured 
or up to about 10 days before harvest. Here we irrigate 12 to 14 times and 
cultivate 10 to 12 times. 
Furrows must be large enough to irrigate without flooding. Flooded onions 
will not bulb properly. 
GATHERING 
As soon as the tops die in the fall, the bulbs should be pulled and about 
four rows put together in each windrow. As soon as the tops are dried, cut 
about one-half inch from the bulb with shears and put into field crates. Stack 
crates in piles of about one truckload each and protect top crates from weather. 
When thoroughly cured, run over grader, sort out scallions and damaged bulbs 
and store in onion house. Stack so that the best of ventilation is assured. Keep 
dry and as near a uniform temperature just above 32 degrees as is possible. 
Repeated freezing and thawing will spoil the bulbs. Moving frozen onions will 
ruin them. Wait until thawed if caught by freeze. Very early onions are 
grown by the transplanting method, the seed being sown in frames or beds, 
on the small onions transplanted when the size of a small lead pencil, to the 
eld rows. 
_ The tops of some Sweet Spanish Onions remain green right up until time 
it is necessary to harvest. The onions may then be pulled and allowed to re- 
main in windrows long enough for drying down the tops.
