FACTORS AFFTING PRCDWTION OF CABBA(, CAULIFOWER AND POTATOES AT HASTINGS
E. N. McCubbin

Varieties.- To produce profitable crops of cabbage, cauliflower and potatoes at
Basting, it is necessary to choose well-adapted, high-yielding varieties that have
good eating and shipping qualities. Variety trials at the Potato Investigations
Laboratory have shown that some varieties of these crops are much better in these
respects than others. Those recommended for use in the area are:

Cabbage Cauliflower Potatoes
Copenhagen Market(early) Snowball X Sebago
Glory of Enkhuizen(midseason) Snowball Y Pungo2
Marion Market(midseason)l Snowball Imperial Red Pontiac
Greenback(midseason)1 Holland Erfurt Red LaSoda
Resistant Glory(midseason)l Snowdrift

Fertilization of Cabbage and Cauliflower.- Generous applications of fertilizer are
needed to grow good crops of cabbage and cauliflower. The fertilizer should supply
the three major plant foods: nitrogen (N), phosphoric acid (P205), and potassium
(K20). Magnesium (Mg0) is generally used in the fertilizer up to two percent as
filler. Other minor elements are seldom needed in the fertilizer for these crops
at Hastings. Fertilizer formulas most generally used in the area are 6-8-8 or
7-9-9. Less fertilizer is needed in plant beds than is needed to grow the crops in
the field. Soils should be sampled in the early fall. When the pH is below 5.0 the
land should be limed to adjust the reaction to pH 5.5 to 5.8 to prevent development
of whiptail in cauliflower, help prevent leaching of plant nutrients and help make
plant nutrients in the soil and fertilizer more available to cabbage and cauliflower.

In plant beds apply the fertilizer with a potato planter in a band in each side
of the row at rates of 1,000 to 1,200 pounds per acre a few days before planting the
seed. When heavy rains occur and leach the fertilizer, seedling plants will show a
light green or yellow color. In this case sidedress the plants with 50 to 75 pounds
per acre with nitrate of soda, nitrate of soda-potash or ammonium nitrate. The side-
dressing may be repeated one or more times as needed to keep the plants green and
growing nicely.

Transplanted cabbage and cauliflower should be fertilized at rates of 1,800 to
2,000 pounds per acre. The fertilizer may be applied in a band in each side of the
row with a potato planter a few days before the plants are transplanted; or it may
be placed in sides of the row 1 to 2 weeks after the plants are transplanted. When
fertilizing after setting the plants, apply the fertilizer with a tractor-mounted
fertilizer distributor 3 to 4 inches deep in the row and about 3 inches away from
the plants in both sides of the row. Do not delay fertilization of the plants
longer than weeks after setting as they ay become stunted.



*Revision of Mimeo Report 59-7.
1Resistant to cabbage yellows and can be grown where the land is known to be
infested with this disease.
2Resistant to corky ringspot and can be grown profitably in infested soil.

Sidedress cabbage and cauliflower 2 or more times during the growing season
with nitrate of soda, nitrate of soda-potash, ammonium nitrate or uramon, supplying
24 pounds of nitrogen per acre per application. The first sidedressing is usually
done 2 to 3 weeks after the plants are set. It is applied on top of the row and
plants when the plants are dry. 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 sidedressings may be needed if rains leach plant nutrients from the soil.
When sidedressing large plants apply it on sides of the row below plants to prevent
burning.

Seeding Potatoes.- Experiments have shown that two-ounce seedpieces of the Sebago
variety produce best yields of potatoes in irrigated land at Hastings. Space seed-
pieces 10 or 8 inches apart in the row. With 40-inch rows this will require
2,000 pounds of seed at the 10-inch spacing and 2,450 pounds of seed at the 8-inch
spacing to plant an acre of potatoes. When planting 2,000 pounds of seed apply
2,200 pounds of 6-8-8 fertilizer or equivalent per acre. For 2,450 pounds of seed
apply 2,500 pounds of the 6-8-8 fertilizer or equivalent per acre. Average yields
of 200 cwt. US 1A potatoes per acre and a minimum price of $3.00 per cwt. will make
the higher rates of seeding and fertilization profitable. For larger yields and
better prices the higher rates of seeding and fertilization will be proportionately
more profitable.
