FACTORS AFFECTING PRODUCTION OF CABBAGE, CAULIFLOER AND POTATOES AT HASTINGS
E.N, McCubbin


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 Pungo(white)2
Marion Market(midseason)1 Plymouth(white)2
Greenback(midseason)l Red Pontiac(red)

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
(P20 ), and potassium (K20). Fertilizers analyzing 6-8-8 or 7-9-9 are most gen-
erally 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 cauliflower, help prevent
leaching of plant nutrients and make plant nutrients in the soil and fertilizer
available to the plants.

Seedbedst 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 de-
pending 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. -x

2Resistant to corky ringspot, Recommended for planting wht dise a
problem, (See Mimeo Report 60-1). ,








Fields: Fertilizer for cabbage and cauliflower should be applied at rates of
1,800 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 fertilizer distributor
3 to 4 inches deep in the row and about 3 inches from the plants. Plants may become
stunted from lack of plant 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 sidedressing 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 40-inches 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 approxi-
mately 1 pound of fertilizer per pound of seed.

Under unfavorable growing conditions and low price for potatoes in 1958 and
1959, the best seeding rate was the use of 2-ounce seed spaced 10 inches apart in
40 inch rows. This requires the use of approximately 2,000 pounds of seed per acre.
The best way of fertilizing this planting is 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 ferti-
lizer per acre would be the better practice. When the future price for potatoes is
expected to be $4.00 or more per hundred-weight, one would be justified in using the
heavier seeding and fertilization rates as mentioned in the preceding paragraph.
