Project

Design and testing of a permanent vegetable production system in Vietnam (PermVeg)

In many South East Asian countries field vegetables are produced in a wet rice based system. Due to ongoing urbanization and increasing wages in cities, the demand for commercially produced vegetables in the SEA region is growing rapidly.

Goal

As a consequence, there is increasing pressure on field vegetable producers to intensify their production. For the local farmers information on sustainable and profitable permanent vegetable production systems is of high value. This study contributes to the improvement of vegetable production, leading to more sustainable production methods and higher farmer’s incomes.

The objective of this project is to test the hypothesis whether continuous vegetable production results in improved soil conditions, higher yields, better product quality and higher financial returns as compared to vegetable growing in rotation with flooded rice.

Results

The scientific relevance of the work is in the innovative design and testing of permanent vegetable production systems for the tropical lowlands.

The project contributes to:

  • Development of innovative and sustainable vegetable production systems for the developing countries.
  • Expertise on tropical vegetable production will be maintained and further developed.
  • Income improvement of the local farmers and to a better year-round supply of vegetables in the Red River Delta of Vietnam.

Timeline approach

2006-2012

The work starts with the theoretical design of permanent vegetable production systems. The rotation of the crops during the year, the potential yields and estimated financial returns, are described in a model. With this model the most promising crops and cultivation systems for permanent vegetable cropping are identified. These options are then tested under field conditions during two years. The design of the model should have universal characteristics and should be easily adaptable for other situations and locations.
