DIVERSIFICATION OF FIELD VEGETABLES IN THE NETHERLANDS: PROSPECTS AND PROBLEMS CONCERNING THE CULTIVATION.

C. van Wijk
In general new field vegetable crops and field vegetable crops with a small area (<400 ha) can be divided into three groups:
  1. Crops which cannot grow in the Dutch climate.
  2. New introduced crops. In here there are 3 subgroups; 2.1 Crops being in the introduction-phase. 2.2 New crops which have already got a small but certain market-position. 2.3 New introduced crops which are not succesful in a short trialperiod of supply.
  3. Existing crops with a small and stable or decreasing area.

In the second group a number of problems are to be recognized which are general for all new introduced crops. Per example the admission of chemicals to control diseases and weed may call for special attention. Often the chemical manufacturers are not interested in an admission because it is too expensive. In the same way breeding new crops is often not interesting to seedcompanies.

The policy of the diversification of field vegetables in the Netherlands is based on more purposes. a) Introduction of totally new and unknown crops happens with more prudence than in the past, and only if marketprospects are very clear. b) Much attention gets the extending of the productionseason of more established new crops c) Minor existing crops get more attention. d) Development of new, more to low temperature adapted varieties is a long and difficult way.
