BASICS OF GREENHOUSE, TYPES OF GREENHOUSE, COMPONENTS OF GREENHOUSE, ENVIRONMENTAL FACTORS AND THEIR EFFECT ON PLANT GROWTH
Greenhouse:
It is a framed or inflated structures covered with transparent or translucent material large enough to grow crops under partial or fully controlled environmental conditions to get optimum growth and productivity.
Principles of greenhouse:
The greenhouse cultivation based upon the principle called as greenhouse effects.
Greenhouse transmit the solar energy inside the structure. This energy absorbed by the crops and the objects inside the house releasing light of long wave length, finally this light does not emit out as the cladding material is non-transparent for these light.
Finally the light gets trapped inside increasing the inside temperature. This rise in temperature in greenhouse is responsible for plant growth in cold climate.
However during summer increase in temperature can be managed by ventilation and cooling system, as in this period temperature rose beyond the critical temperature.

Presented by Northland Community & Technical College Specialty Crops Management Instructor Thaddeus McCamant and grower Dallas Flynn at the 2009 Minnesota Statewide High Tunnel Conference in Alexandria, MN on Dec. 2-3, 2009.
In a Bengali proverb there is a wise saying 'Age dorshon dhari pore gun bichari' (i.e. to be nice to look at first and then make a judgement on its quality). Based on the proverb, a few colourful vegetable varieties have been developed at BARDC (BRAC Agricultural Research & Development Centre), Gazipur, Bangladesh. Coloured vegetables plays a very important role when these vegetables are included in our regular diet. These colourful vegetables not only have the decorative value but also have the nutritional value as well. In Bangladesh red okra, red spinach, white pumpkin, purple hot pepper, red yard long bean has been developed at BRAC Agricultural Research & Development Centre and preliminary investigation revealed that these vegetables have increased level of anthocyanin, carotene, iron, sulphur etc. However, more research is needed before releasing them into the market. #Suggested link of my you tube video on colourful vegetable variety development:https://www.youtube.com/watch?v=kijF78rwhaY&t=52s

Vegetables constitute an integral component of the cropping pattern but the increasing pressure on food and cash crops has limited the area under vegetables to about 0.62 million ha, which is 3.1% of the total cropped area. Vegetables fit well in most farming systems due to shorter maturity period.
Vegetable crops are very important due to their higher yield potential, higher return and high nutritional value and suitability for small land holding farmers. Vegetables provide proteins, minerals and vitamins required for human nutrition. In Pakistan, the daily per capita intake is low, being about 100 grams compared to the recommended consumption of about 285 grams. In view of population increase, land degradation and water scarcity, there is a need to substantially increase vegetable production in the years to come and to attain self-sufficiency as well as to increase the exportable surplus. However, in the past, development efforts in agriculture sector were primarily focused on production and development of cereal crops; in spite of the fact the vegetables provide maximum output per unit area.

• Brambles 3’ apart with 132 plants per 30’x96’
tunnel
• Bramble Varieties
• Primocane (thorny) – Prime Jim and Jan
• Floricane (thornless) Arapaho, Apache, Natchez,
Navaho, Chester, Triple Crown, Ouachita, Doyle
6. Blackberry Nutritional Value
• Healthiest food that rank highest in antioxidants- American Journal
of Clinical Nutrition (2006)
• Blackberry extract is a rich source of Anthocyanins
• Anthocyanins are a group of naturally occurring phenolic compounds
related to the coloring of plants, flowers and fruits.
• Antioxidant and anti-inflammatory properties
• Fruits produce these compounds to protect themselves from UV
damage
• The good: Very low in saturated fat, cholesterol and sodium. Good
source of Vitamin E (Alpha Tocopherol), Folate, Magnesium,
Potassium and Copper, and a very good source of Dietary Fiber,
Vitamin C, Vitamin K and Manganese.
The bad: A large portion of the calories comes from sugars. But
they’re GOOD TASTING !!!!
7. Soil Preparation
• Composted ½ mushroom
compost and ½ dairy
manure
• Mixed one wheelbarrow
per ten foot of row and
tilled into soil
• Perform soil nutrient
analysis
• Mulched around plants
with mushroom compost
or woodchips
8. Irrigation System
• Installed drip irrigation
• Emitters within 8” on either side of
bramble
• Each emitter releases ½ gallon per
hour.
• Semi automated system
• Sensor and controller provide 6
zones with 6 irrigation times per
zone
• Sensor provides moisture content
(%), soil temperature, and EC
• Irrigation cycle suspended above
pre-set soil moisture content
• Irrigated in 1.5 hour cycles at 7 am
and 6 pm
• Irrigation increased to three 1.5
hour cycles during fruiting
9. Fertigation System
• Installed EZ Flow (1 gallon) inline fertigation
system
• Applied organic liquid fertilizer containing fish
• Fish Aqua – OMRI approved
• Discovered fish emulsion based fertilizer clogs
emitters
• Drip tape not clogged by emulsion but emitters too
close = wasted water and fertilizer
• Install drip tape future high tunnels
• Plan to fertigate one time per week
• Perform soil analysis beginning and end of season,
leaf analysis during growing season
10. Weed Management
• Three Techniques Employed:
1.Wood chips, saw dust
2.Layer of cardboard boxes and
wood chips
3.Mushroom compost, straw
4.Black polyester material (14-
24 mil) in 3’ and 6’ wide
sections
5. One mil black plastic within
rows - tomatoes
• Polyester generally most
effective and least labor
intensive
11.
12. Trellis System
• Modified V/T system with
bottom “T” 36” and top
“T”66” above ground
• Run two strands of wire at tip
of each crossbar
• Alternative: 4x4 non treated
posts that are notched. Insert
2x4 “T”s
• Space posts 10’ apart
• Year 1 canes tied to one side
of the strand and will bear
fruit in year 2
• Fruit bearing year 2 canes will
be pruned to ground to make
room for the year 3
primocanes.
13.
14. Bramble Management
• Pruned Prime Jim and Jan to ground in winter.
• Tip when new canes reach five feet in summer
• New blossom supporting laterals appear within
weeks
• Continual pruning generates new blossoms
• Secure floricanes to two wires. Tip at 5’. Cut 4’
laterals back to 18” and secure to two wires.
• Prune to ground as soon as done bearing
15. Fruiting Period
• Primocanes
• Fruiting began early August
• Blackberries averaged 6-15 grams
• Temperatures over 100° F hindered drupelet
formation
• Brambles consumed large amounts of water
• Difficult to harvest berries at optimal ripeness due to
softness
• Thorns required gloves and heavy flannel shirt
• Last harvest on Nov 18th (turned off supplemental
heat)
• Numerous berries and blossoms still remained
on plant
• Total yield from 12x40’ tunnel = 100 pounds
• Thornless Floricanes
– All bore some fruit
– Rabbits girdled canes on new first year growth.
Reduce production by 50%
– HT1 Readstown fruited June 15th to August 6th
– HT1 Rosemount fruited August 1st to September 7th
– HT1 Readstown = 12 cases (one case = 12 5.6 oz
clams)
– HT1 Rosemount =10 cases
– Yield lower than expected for 2nd yr canes
– 2nd year primocanes 20 times lateral growth as first
year
– Natchez largest, sweetest and most berries by
volume
17. Growth Characteristics
• Brambles not shaded in Wisconsin
• studier canes
• experienced faster growth
• developed more laterals
• Higher blossom counts and yields on
primocanes in west vs. east end of high tunnel
due to two extra hours of direct sunlight
• Better growth on root stock vs. culture stock
• Inconsistent growth of same variety frequently
observed
18. Winterization
• Winter Protection
• Installed thermostatically controlled
170,000 BTU propane heater that fires at
5° F and deactivates at 9 ° F (minimum
temperatures of zone 7b climate)
• Forcing dormancy is lengthy process due to
elevated temperatures and snow
insulation
• Pest Issues
• Rabbits girdled floricanes over several days
• Trapped the critter but would have
destroyed crop in two weeks or less
• Rabbits avoided primocane variety
• Final irrigation cycle on November 7th
• Heavily watered previous week
• No moisture over winter is a concern
• Elevated February temperatures may promote
premature budding.
• Ventilated conventional high tunnel thru
the use of exhaust fans and monitor signs
of budding
• Cooled solar thermal high tunnel with fans
19. Market Potential
• Wholesale MSP food brokers usually pay $7-8/lb.
organic June 1 thru Nov. 30
– Potential Dealers: Sun Belle Inc, Bergin Fruit and Nut
Company, Organic Valley Farms, J & J Distribution
• Direct Market
– Supermarkets/Retail Outlets

21. Future Tasks
• Submitted SARE proposal to research
methods to extend the season into
September and October
– Install shade cloth
– Use various mulches
– Adapt pruning methods
22. Intercropping
• Intercropping is the practice of growing two
or more crops in proximity
• Important not to have crops competing with
each other for physical space, nutrients, water,
or sunlight
• SVF – blackberries, raspberries, strawberries,
tomatoes, peppers, melons, eggplant, herbs
• Blackberries do not generate significant
revenue until third growing season
