FACTORS AFFECTING PRODUCTION OF CABBAGE, CAULIFLOWERAND PQ ATOES AT HASTINGS
E. N. McCubb#xi-:.
VARIETIES.- In producing satisfactory crops of cabbage, cauliflower and pota-
toes at Hastings, it is important to select high-yielding varieties that possess
good shipping and market qualities. Tests at the Potato Investigations Laboratory
have shown that some varieties of these crops are much more satisfactory than
others. Those recommended are as follows:
Cabbage Cauliflower Potatoes
Copenhagen Market(early) Snowball X Sebago(white)
Glory of Enkhuizen(midseason) Snowball Y Red Pontiac(red)
Marion Market(midsea on)l
FERTILIZATION OF CABBAGE AND CAULIFLOWER.- Liberal amounts of fertilizer
are required to grow satisfactory crops of cabbage and cauliflower at Hastings.
They should contain the three major plant food elements, nitrogen (N), phosphoric
acid (P205), and potassium (K20). Fertilizers analyzing 6-8-8 or 7-9-9 are most
generally used in the area at present. Less fertilizer is required to grow
transplants in the plant bed than is needed to grow the crops in the field.
Acid soils should be limed to pH 5.5 to prevent development of whiptail in cauli-
flower, help prevent leaching of plant nutrients and make plant nutrients in the
soil and fertilizer available to the plants.
Seedbeds: Apply the fertilizer in a band in each side of the row at rates
of 1,000 to 1,200 pounds per acre a few days before the seed are planted. Heavy
rains may leach the fertilizer nutrients. If rains occur and the plant foliage
shows a light green or yellow color, sidedress plants with 50 to 75 pounds per
acre nitrate of soda or nitrate of soda-potash. Repeat the sidedressing one or
more times depending on the amount of rain and growth and appearance of the plants.

1Resistant to cabbage yellows and should be grown where the land is known to
be infested with the cabbage yellows organism.
Fields Fertilizer for cabbage and cauliflower should be applied at rates
of 1,80 to 2,000 pounds per acre. It may be applied in the row with a tractor.
drawn fertilizer distributor a few days before the plants are transplanted; or
placed in sides of the row 1 to 2 weeks after the plants are transplanted. In
the latter case, the fertilizer should be applied with a tractor-mounted ferti-
lizer distributor 3 to 4 inches deep in the row and about 3 inches from the
plants. Plants may become stunted fr2 oma pgant food if fertilization is
delayed longer than 3 weeks after setting.
Cabbage and cauliflower generally require 2 or more sidedressings during
the growing season with 150 pounds of nitrate of soda or nitrate of soda-potash
per acre per application. The first sidedressing is usually applied on tops of
the row when the plants are dry 2 to 3 weeks after transplanting. The second
sidedressing is applied 30 days after the first one unless leaching rains occur
and the plants show a light green or yellow color. In this case the second
sidedressing may be applied earlier. Additional aidedressing may be required if
rains leach plant nutrients. When sidedressing large plants apply the fertilizer
on sides of the row below plant leaves to prevent burning,
SEEDING POTATOES.- Until 1958 tests showed the most profitable way to seed
Sebago potatoes was with 2-ounce seed spaced 8 inches apart in rows 40winches
apart. This required the use of 2,450 pounds of seed per acre, The best way of
fertilizing these potatoes was with 2,500 pounds of a 6-8.8 fertilizer per acre,
or approximately 1 pound of fertilizer per pound of seed.
Under unfavorable growing conditions and low prices for potatoes in 1958,
the best seeding rate was the use of 2-ounce seed spaced 10 inches apart in
40 inch rows. This required the use of approximately 2,000 pounds of seed per
acre. The best way of fertilizing this planting was with 2,200 pounds of a
6-8-8 fertilizer per acre, or 1.1 pounds of 6-8-8 fertilizer with each pound
of seed. Under stress economic conditions, it appears that use of the lesser
amounts of seed and fertilizer per acre would be the better practice.
