Manual: Greenhouse sweet pepper production

Posted on by Luyen

Greenhouse sweet peppers are primarily grown in three colours: green, red and yellow. No matter what the final colour of the pepper, all sweet peppers start out green in colour and the final colour develops as the fruit ripens.

In general the price of red and yellow sweet pepper is higher than green sweet pepper, making it more profitable to harvest sweet peppers grown in a greenhouse red or yellow. The sweet pepper plants can be kept in production from 4 – 8 months depending on the variety and production system used. Most farmers in Vietnam try to grow a sweet pepper crop for one year.

Manual: Hydroponice vegetable production

Posted on by Luyen

Hydroponic cultivation is an artificial means of providing plants with support and a reservoir for nutrients and water.

The simplest and oldest method for soilless culture is a vessel of water in which inorganic chemicals are dissolved to supply all of the nutrients that plants require. Often called solution culture or water culture, the method was originally termed hydroponics (i. e., “water working”) by W. F. Gericke in the 1930s. Over the years, hydroponics has developed throughout the world as a commercial means of growing both food and ornamental plants. A growing media is sometimes used in hydroponic systems to provide plant support, and retain some nutrients and water. The growing media is then placed inside plastic bags, slabs or containers.

Manual: Potato production

Posted on by Luyen

Potato is an important crop in Vietnam. The main production area is in North-Vietnam, but in the Central Highlands (Lam Dong Province) potato is also an important crop.

Potatoes are a high nutrient value, besides carbohydrates potatoes are also a good source of vitamins, minerals and fibres. In the past potatoes were mainly grown for fresh consumption, but in recent years the potato volume produced for processing has increased. The characteristics of potatoes suitable for fresh consumption and processing vary and this if often related to the potato variety characteristics. The main problem for potato production worldwide is late blight (phytophtora infestans) and this is also in Vietnam the case. In order to come to a successful potato crop many point should be considered and managed and with this leaflet we like to provide some advice and ideas.

Manual: Irrigation of vegetable crops

Posted on by Luyen

Irrigation is one of the most critical of all production practices. To provide conditions for optimum plant growth it is essential to become familiar with the factors that influence soil moisture.

Plants evaporate which has to be compensated either by rainfall or in an artificial way. Because of storage capacity in the soil, water can be buffered for certain time. The buffer capacity depends on the soil type. Clay soil has a larger storage capacity then sandy. The water storage capacity is also increased by the amount of organic matter in the soil. The water storage capacity for a crop depends on intensity and rooting depth. Enough moisture in the soil is important for plant growth, soil processes (release and transport of minerals) and for soil cultivation.
