Cassava Production Technoguide

Cassava is one of the important root crops in the Philippines because of its many uses. Aside from being used as food, and feed ingredients, cassava is also used in the manufacture of industrial products. It is also used as raw material in the production of ethanol. Moreover, cassava can be processed into different food products with higher economic value.

The demand for cassava as raw material for industrial uses dramatically increased. However, this demand is not fully satisfied due to low cassava production.

This technoguide contains the recommended cultural management practices for cassava to ensure high yield.Some information included here are results of researches conducted by PhilRootcrops. This technoguide can be used by farmers, technicians and other users to increase cassava production in the country.

Site Selection

Select a site with the following characteristics:

  •   Flat or undulating slope (not more than 15%) If the slope of the area is very steep, use water and soil conservation techniques (Example: Sloping Agricultural Land Technology or SALT specifically the establishment of contour hedgerows).
  •   An open field
  •   Sandy loam to clay loam soil
  •   Soil pH ranging from 5.5-6.5
  •   Enough rainfall or water source that can support the growth of cassava plants throughout the year Cassava plants produce low yield and deformed roots when subjected to drought stress especially during the first 3 months after planting.
  •   A well-drained area; no waterlogging for more than 24 hours Young cassava plants (1-3 months old) will have stunted growth while mature cassava plants will have rotten roots when waterlogged for more than 24 hours.

Land Preparation

Plow and harrow the field twice using a tractor or animal-drawn plow and harrow. Do these operations when there is enough soil moisture. Plow the field at least 6 inches deep.
