Soil problems are a major cause of low production levels in many cropping ventures. The most interesting fact about cassava is that it can even grow in nutrient deficient soils. Although farmers may not deliberately conserve cassava genetic resources, they do so through traditional practices that ensure on-farm retention of varieties over years. You should obtain your planting materials as close as possible to planting time. Cassava … The SAH involves the use of modified soil which holds plant roots in planting pots with little water. Select cassava stems from disease-free plants. Long cuttings give higher yields than short ones. You use fresh, white Cassava from the garden and you boil these roots for 20 minutes.

Planting material and treatments Planting material from the cassava cultivar M Col 1684 used in this study was obtained from a long-term N, P, K trial that began in 1982 and had completed its 8th year of consecutive planting. Cassava is predominantly consumed in boiled form, but substantial quantities are used to extract cassava starch, called tapioca, which is used for food, animal feed, and industrial purposes. Cassava is one of those crops that uses part of the plant for propagation. Select and use improved, healthy, and pest/disease free cassava … The older root tubers become lignified. Let us consider these factors that contribute to the quality of cassava planting materials/stem cuttings necessary for a good yield. Soil Requirement for Cassava Farming. 0000008836 00000 n They have poor nutrient reserves and it is because the shoots which develop from such stems are weak and only a few, small tuberous roots are produced.

Have you ever wondered how the egg becomes chick?. Stem cuttings, 15-30 cm in length, are used as planting material to establish commercial crops of cassava. And it is not common that cassava planting materials for local varieties are sold or bought. These factors are necessary for the sprouting of vigorous plants capable of producing a good number of roots and giving good cassava yield.
