Some Factors Affecting Production of Potatoes, Cabbage
and Cauliflower in the Hastings Area
E. N. McCubbin
VARIETIES.- A very important step in the production of good crops of cabbage,
cauliflower and potatoes at Hastings is the selection of adapted varieties. Tests
at the Potato Investigations Laboratory have demonstrated that some varieties of
these crops are high-yielders and possess good shipping and marketing qualities;
while others are not acceptable.

FERTILIZATION OF CABBAGE AND CAULIFLOWER.- Production of cabbage and cauli-
flower in the Hastings area requires liberal applications of fertilizers containing
the three major plant nutrients, nitrogen (N), phosphoric acid (P205), and potash
(K20). Analyses of the fertilizers most generally used in the area are 6-8-8 and
7-9-9. Loss fertilizer is needed to grow transplants in the seedbed than is re-
quired to grow crops in the field. When the seedbed and field soils are acid they
should be limed to pH 5.5 to prevent the development of whiptail in cauliflower,
help prevent leaching of plant nutrients and make plant nutrients in the soil and
fertilizer more available to the plants.
Seedbeds:- For seedbeds apply the fertilizer at rates of 1,000 to 1,200
pounds/A in bands in the row a few days before the seed are planted. When the
fertilizer is leached by heavy rains or when the plant foliage shows a light green
or yellow color, sidedress the plants with 50 to 75 pounds/A of nitrate of soda or
nitrate of soda-potash. The sidedressing may be repeated one or more times depend-
ing on the number of heavy rains and the growth and appearance of the plants.

Fields:- Fertilizer for both cabbage and cauliflower should be applied at
rates of1,800 to 2,000 pounds/A. It may be applied in a band in both sides of the
row with a tractor-drawn fertilizer distributor a few days before the plants are
transplanted; or placed in sides of the row 1 or 2 weeks after the plants are trans-
planted. In the latter case place the fertilizer 3 to 4 inches deep and about
3 inches from the plants. Application of the fertilizer in sides of the rows may
be done with a tractor-mounted fertilizer distributor and disks in one operation.
Do not delay fertilization more than 3 weeks after the plants are transplanted or
ey my e stunted. -'
Sidedress cabbage and cauliflower 2 or more times during the growing season
with 150 pounds of nitrate of soda or nitrate of soda-potash/A per application.
Apply the first sidedressing on tops of the rows when the plants are dry 2 or 3
weeks after transplanting. The second sidedrossing is applied 30 days after the
first one unless heavy leaching rains occur and the plants show a light green or
yellow color. If this occurs the second sidedressing may be applied earlier.
Further sidedressings may be applied as needed when the plants fade to a light
green or show a yellow color. When sidedressings are made to large plants apply
them to sides of the row below plant leaves to keep from burning them.
SEEDING POTATCES.- Best yields of Sebago potatoes at Hastings have been
secured by planting 2-ounce seedpioces 8 inches apart in rows 0U inches apart.
This requires the use of approximately 2,450 pounds of seed per acre. This rate
of seeding Sebago potatoes has consistently produced high yields of potatoes and it
has resulted in the best returns after subtracting cost of the seed, picking-up the
potatoes, hauling them to the grader, grading, packaging and selling them. Best way
of fertilizing Sebago potatoes planted at the rate of 2,450 pounds of seed/A on
irrigated land has been the use of 2,500 pounds/A of a 6-8-8 fertilizer approxi-
mately 1 pound of fertilizer per pound of seed.
