The normal facility structures to successfully cultivate paprika are very
extensive from the latest VENLO type glass greenhouse to polyethylene-coated tunnel.
If a structure for cultivating cucumber or tomato is established, paprika may be also cultivated in the facility.
However, any cultivation facility without heating system or inferior ventilation such as plastic facility is not proper for the cultivation.
Paprika is very vulnerable to gray mold/bunch rot and it is so important to maintain the facility at low humidity.
In any facility not suitable for the above, paprika would be much more vulnerable to gray mold/bunch rot than other crops.
Of course, a specific house may be profitable or not in view of economy and cultivation. As other crops,
paprika depends on lighting conditions during winter season for successful growth.

| heating system |
Paprika is very sensitive to ambient temperature and ground temperature(badge temp.) while
the fine condition for growth directly results in the quantity. Therefore, the heating system in the first cultivation should be preferentially considered. |
| ventilation |
For alternatives for ventilating glass greenhouse and other facilities, there are two methods as natural ventilation and compulsory ventilation. |
| temperature control |
Automatic temperature controllers and sensors are installed inside boxes so
that they are not exposed to direct sunrays while the temperature continues to be sensed by air through a small electric fan. |
| thermal screens |
Paprika requires relatively higher temperature than
tomatoes therefore it is better for cultivators to install fixed or movable screen. |
| temperature recording |
It is very important to sense and record temperature to control ambient and ground temperatures.
Therefore, temperature recording system is one of required systems for crop cultivation. |
| carbon dioxide equipment |
Once ventilation is completely opened, CO2 reaches up to 300ppm,
which is normal level in atmosphere, and carbon dioxide is rapidly supplied as soon as any plant starts assimilation. |
| irrigation systems |
Irrigation into a peat or rock-wool requires more preciseness, especially for any peat module or container cultivation of which volume is not huge,
irrigation should be separately regulated. In the situation, accurate irrigation system is essential
while it needs frequent cleaning with filtration attached. For any irrigation systems,
it should be installed so that liquid manure could be properly supplied. |

Paprika is an annual plant belonged to Solanaceae family, Capsicum genus and Annuum species and one of 6 pepper subspecies of which type is a
representative sweet pepper with twisted pepper featuring little impure taste and
various colors,
for which paprika is very widely used for salad or when a dish requires colors.
In addition, comparing to red pepper species, the sweet species such as twisted pepper and
paprika are developed normally in northern countries,
so U.S, European countries,
Brazil and Japan have cultivated a lot, and while our dietary life is getting familiar with western style,
we¡¯ve got more demand. To meet the increased demand, paprika is
cultivated a lot in greenhouse or plastic house facilities.
Containing rich Carotin besides vitamin A and C, paprika is apparently similar to normal pepper plant but its leaves are wider and unifoliate while the leafstalk is about 0.5~2.5cm.
In addition, leaves are egg-shaped and the edge is flat and even.
The fruits are very diverse from cylindrical one, singular cylindrical one and up to conical one while the size scales from 3g to 300g.
The length of paprika is about 0.5~1.5m while the lower part of the stalk becomes ligneous, shaping as a small tree.
The flower comes out in summer and its diameter is 1~1.5cm wide.
The fruit is large and lion¡¯s head shaped, reaching approximately 5~7 cm long and 4cm wide with several vertical grooves.
Paprika flesh is 5mm thick and the inside is vein. The seed is yellow white and flat with 3~4mm long, 2~3mm wide and 0.5~1mm thick.
Each gram contains 150~180 seeds while a liter of seeds weighs 480~500g; a thousand weigh about 6g. |
