Vegetable Production Midterm

Which plants require lower sunlight hours (3-4 hours)

Leafy greens (Lettuce, chard, parsley, arugula)

Which plants require medium sunlight (4-6 hours)

Root and tuber plants (beets, carrots, potatoes, Radish)

Which plants require high sunlight (6-8 hours)

Fruiting vegetables (peppers, tomatoes, watermelon, eggplant)

Beyond sun/shade, why does it matter to consider slope when planting?

Southern slopes warm up faster in spring - earlier crop, and cold air pools in valleys (like water)

What are the benefits of companion planting?

Repels pests and attracts beneficials, efficient space usage, enhances plant growth

What plants encounter problems with debris in the soil

Spinach, Brassica greens

Why would you chose to direct seed over transplant?

It is suitable for large scale/high density plantings and not all plants are tolerant of transplanting

Why would you chose to transplant over direct seed?

Establishes faster in field and good for season extension

What is required for direct seeding?

Seed metering + opening and closing a seed furrow

Why might you use a cold frame over a greenhouse?

Cuts out electricity costs

How deep should transplants be planted in the field?

Same depth as in the nursery/container

What would require planting seeds deeper in the field?

If the soil is sandy, dry, or during consistent hotter temps

What angle of light incidence is most ideal for the leaf

90 degree angle

What are red and blue light responsible for respectively in plant growth

Red - vegetative, Blue - flowering

Vegetable LDP (Long Day Plant) examples

Lettuce, potato

Vegetable DNP (Day Neutral Plant) examples

Tomato, cucumber

When does SD response start

The end of summer (potato)

When does LD response start

Late spring and early summer

Examples of plants that require vernalization

Biennials: carrots, celery

What is veralization

Any cold temperature treatment that induces or promotes flowering. “Making ready for Spring”

What helps to increase temperatures in the greenhouse and field respectively

Greenhouse: Black plastics, heaters Field: raised/hot beds, high tunnels/row covers, overhead irrigation during frost (strawberries)

What helps to decrease temperature in the greenhouse and field respectively

Greenhouse: Misting to increase RH, growing under shade Field: Organic mulches, deeper planting

Advantages and disadvantages of high tunnels

Advantages: Season extension, shade in summer, protection Disadvantages: Maintenance, higher risk of salinity, different pests
