A. Site Selection

Cassava grows best in a warm humid climate with a well-distributed rainfall of 1,000 to 1,500 

millimeters per year. Cassava can be planted in practically all types of soil but performs best in well-drained, light to medium-textured soil such as sandy loam, silt loam and clay loam. However, cassava does not perform well  with elevation exceeding 1,000 meters above sea level or water logged areas.


Flat and undulating lands with slopes ranging from 0-8% are suitable for cassava production. Areas with greater than 8% but not more than 15% slope may be considered provided erosion control measures are put in place. The presence of farm-to-market roads, availability of farm labor and accessibility to existing SMFI feed mills/buying stations are important considerations prior to establishment of cassava plantations.


B. Preparation of Planting Materials

Obtain mature stalks from healthy stand of SMFI-recommended cassava varieties that are at

least 8 months old. Freshly-harvested stalks when planted exhibit superior vigor compared to stored planting materials. If planting is delayed, store the planting materials in an upright manner under a cool and shady place. Recommended varieties include Golden Yellow, Lakan 1, KU-50 among others.





Golden Yellow

(Pr-C 24)



Most commonly available multi-purpose variety

Lakan 1

(UPLB Cv-2)



Multi-purpose variety; DA’s national check variety


(NSIC Cv-22)



Industrial (non-edible) variety; DA’s national check variety

C. Land Preparation

Land preparation is similar to any upland crop. Clear the area of existing vegetation and debris. For flat areas, tractor cultivation is recommended. Perform disc plowing and disc harrowing depending on the soil type and weed incidence. For sloping areas, use animal-drawn cultivation with furrows oriented along the contour of the terrain.


D. Planting

Using a sharp bolo, cut the cassava stems into stakes one (1) day before planting. Prepare cutting with at least 5 nodes or approximately 20 cm in length. Recommended distance of planting is 0.75 - 1 meter between rows and 0.70 meter between hills. The actual planting distance may vary depending upon the availability of planting materials and the inherent fertility of the soil. For areas with distinct wet and dry climate, it is recommended to plant at the start of the rainy season. In areas with evenly-distributed rainfall, it is acceptable to plant anytime of the year. Plant the cuttings on ridges in either vertical or slanting position. Two thirds of the stalk length must be buried or covered with soil. Insure that the mature end of the cutting is buried in the soil. Replant missing hills 10 -14 days after planting.


E. Fertilizer Application

Before planting, submit soil sample for soil analysis to determine the amount and kind of fertilizer needed. If fertilization is necessary, fertilizer application is performed 30 to 60 days after planting. For a yield level of 25 tons of fresh roots per hectare, cassava will require 20 sacks of organic compost, 2 bags of urea and 2 bags of muriate of potash.


F. Cultivation and Weeding

A thorough land preparation is the key to reduced weeding activity. Cultivate the soil 14-21 days after planting to reduce weed growth by passing an animal-drawn implement in between rows. Perform a similar operation 2 months after planting depending upon crop establishment and weed population. Cassava requires approximately 3 months of weed-free condition for optimum yield.
