State and explain four ecological requirements of cassava cultivation

State and explain four ecological requirements of cassava cultivation

Answers

Faith
1.Rainfall: Range between 500 -2500mm annually. Should be well distributed especially at the lower ranges (500 -1000mm). However the crop can survive drought for 5-6 months once established. Thus the crop is highly drought resistance

2.Soil: Do well in a wide range of soil and soil conditions
Ideal soil should be sandy loam, well drained, deep and with high organic matter contents
Shallow or stony soils are not good as they restrict tuber expansion and make harvesting difficult.
-Ideal soil pH is 5-9. Below pH5 (Acidic soils), the crop do not grow well thus liming is required. Normally this is rarely done as cassava is a poor man’s crop.

3.Temperature and altitude: Needs high temperatures for growth and tuber formation
Best altitude s are below 1500masl. Thus dry areas in high lands are not good due to low night temperatures that may fall below 160C.

4.Photoperiod/day length
Cassava is a short day plant. This is not critical in Africa due to 12 hr system. In temperate areas where the day length is a problem the crop grows a lot of vegetative parts at the expense of tubers.
