Notes on the culture of individual plants have been
developed to provide an easy-to-use guide, a summary of a wide
range of information concerning the culture, nutritional value,
harvest, and storage of specific food crops. These are not
intended to be comprehensive references, and you may need to
consult other materials to obtain very detailed information. In
most cases, though, the culture notes should provide enough
know-how to get a crop from seed to harvest. The following key
will help to explain the various terms on each food crop fact
sheet. |
|
ENVIRONMENTAL PREFERENCES 
Light
Sunny - requires direct light at least 6 hours per day, prefers
10 hours per day. |
|
Tolerates partial shade - will do well with fewer than
8 hours of sunshine per day, but probably needs at least 5 hours
per day. |
|
Prefers Shade - more than 6 hours of direct sunlight
may be harmful; prefers filtered light, probably needs at least 3
to 4 hours of light per day. |
|
Soil
Well-drained - water does not stand or remain puddled for more
than 24 hours after a hard rain. |
|
Deep - at least 8 to 12 inches of topsoil or loose
subsoil; no shallow hardpan. |
|
Loam - soil composed roughly of equal portions of clay
and sand, with a reasonable amount of humus; good garden soil. |
|
Fertility
Results of soil tests can be used to indicate the basic fertility
level of soils. Soil testing does not indicate nitrogen levels,
due to variability. |
|
Pounds per 1000 square feet P2O5
| Low |
0 to .5 pounds |
| Medium |
.6 to 1.9 pounds |
| High |
2.0 + pounds |
|
|
Temperature
Approximate ranges of daily mean temperature preferred for
optimum growth. |
|
Moisture
Amount of rainfall or supplemental watering needed for optimum
growth; more for sandy soils, less for clay. |
|
Average - roughly 1 inch of water per week. |
|
Moist - roughly 1 to 2 inches of water per week; soil
should be well-drained. |
|
CULTURE 
Planting
Specific information needed to get plants started, such as when
to seed, whether to start plants indoors, best transplant time,
etc. |
|
Spacing
Optimum distances between plants and rows. |
|
Hardiness
Very hardy perennial - can withstand winter extremes with only
slight protection. |
|
Hardy perennial - can withstand winters with protection
in colder areas. |
|
Hardy annual - can withstand frosts in spring and fall;
may need protection from heavy frosts or freezing. |
|
Half-hardy annual - can withstand light frosts, but not
heavy frosts or freezing. |
|
Tender annual - frost will seriously damage plant
tissue. |
|
Very tender annual - frost will destroy tissues; needs
warm weather for growth. |
|
Fertilizer Needs
Refers to relative levels of nutrient uptake from the soil. This
information can be used to group similar types of plants, so that
fertilizers may be applied to sections of the garden according to
plant needs. |
|
CULTURAL PRACTICES 
Gives general growing information. Includes proven methods for
increasing production and/or decreasing pest problems. Unique
growing suggestions may be included. |
|
COMMON PROBLEMS 
Gives a general list of the most common diseases, insects, and
cultural problems of the crop. Identify the cause of the problem,
review non-chemical and preventative control information, then
refer to current Pest Management Guides or contact your Extension
Agent for specific chemical control information. |
|
HARVESTING AND STORAGE APPROXIMATE YIELDS

These figures vary according to the variety, local environmental
conditions, planting designs, and cultural practices. |
|
Amount to raise
These figures are average ranges per person. Specific amounts
will vary depending on projected usage, whether fresh or
processed, and according to personal preferences. (Also refer to
table 10.9) |
|
Storage
Optimum storage conditions; gives temperature ranges and % RH
(percent relative humidity). |
|
Preservation
Suggestions for preserving the crop over an extended period. See
Extension publications on food preservation for specific methods. |
