Manual: Irrigation of vegetable crops

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.

Manual: Scouting of pests and diseases in crops

Crop scouting is an essential part of Integrated Pest Management (IPM). IPM uses field specific information and improved decision making to protect a crop’s yield and quality while minimizing the use of crop protection products. Crop scouting provides field specific information on pest and disease pressure within a crop.

In order to choose the best pest or disease control management option it is very important that crop scouting is done timely and accurately.

  • Timely: for most crops it is recommended to scout the crop at least once per week and more often when favourable conditions occur for the development of certain pests or diseases.
  • Accurately: a pest or disease needs to be identified and the level of the pest or disease present in the field needs to be determined accurately to be able to select the best control strategy.


When implemented successfully crop scouting will reduce the amount of crop protection products used while increasing the yield and quality of a crop.
