ONIONS.—The onion (_Allium cepa_[6]) has been cultivated from early
times, and its native country is unknown. As it is mentioned in sacred
writings it is supposed that its home is in the far East. Onions thrive
best on old ground, especially if it is a light, sandy loam. The onion
field should be nearly level, clear of weeds, and liberally supplied with
the best well-rotted manure; guano and superphosphates are excellent for
onions. Deep plowing is not necessary. The amount of seed to be used
depends upon the kind of onions desired. If they are to be pulled for
early market, more seed is required than when they are to attain their
full growth.
There are many varieties of onions grown from seeds. The Yellow Danvers,
White Portugal and Weathersfield Red are well known sorts, representing
the three prevailing colors. Onions are largely grown from sets, that is,
bulbs that have ripened while quite small, and when set out grow and form
large onions. The small size and early maturity are due to sowing the
seed thick. From thirty to forty seeds are sown to each inch of the row.
The sets are mature when the leaves begin to wither, and are then removed
and dried. In planting the sets they are placed in rows about four inches
apart.
The “Potato Onion” or “English Multiplier” is propagated by offsets. An
onion of this class, if planted in the spring, will produce a cluster
of small ones around it. These small onions will grow into large ones
the next season. There are several sorts of onions that bear clusters
of small bulbs upon the tops of the flower stalks, in place of seed
pods. The “Tree,” “Top,” and “Egyptian” onions are of this class. These
bulblets, when planted, produce large bulbs, and these latter, when set
out the following season, throw up stalks bearing bulblets.
Onions are ready for harvesting as soon as the leaves droop and become
dry. The bulbs should be well cured and placed in a dry, cool, storage
room. The crop is sometimes badly injured by smut, especially when onions
have been grown upon the same soil for many years. The onion maggot
causes some destruction. Guano and unleached ashes, when scattered over
the bed, have both proved of value.
The above is only a brief consideration of five of the leading garden
vegetables. The first four, namely: Cabbages, turnips, carrots and
beets, are to a great extent farm crops, well suited for live stock. The
composition of these is as follows:
DRY MATTER. ALBUMINOIDS. FAT. STARCH, SUGAR, ETC. ASH.
Cabbage 14.3 2.5 0.7 7.1 1.6
Turnips 8.5 1.0 0.15 5.8 0.8
Carrots 14.1 1.3 0.25 9.6 1.0
Beets 18.5 1.0 0.1 9.1 0.8
