Scientists working on cassava breeding are now using the Semi-Autotrophic Hydroponics (SAH) technology to rev up the propagation of clean cassava planting materials. The current high demand for cassava is not being met because of the lack of planting materials and capability for mass propagation in a short period. Tissue culture carried out in laboratories is one established method for mass production of clean planting materials. Frequent irrigations are needed in the conditions of drought. multiplication of planting material in cassava through tissue culture techniques such as shoot initiation, micropropagation, rooting and hardening is developed. Relationship of Cassava Mosaic Severity in Planting Material to Mosaic Development, Growth and Yield of Cassava in Zaire - Volume 23 Issue 2 - A. Muimba-Kankolongo, K. Phuti These cuttings are selected from the leafless woody portion of the stem of plants normally older than nine months. The propagation of these new cassava culti-vars is by cuttings. This method is not only limiting in the numbers of planting materials but is also cumber-some, and labour intensive. This crop becomes ready for harvesting in about 12 months of the plantation on the main field whereas short duration variety takes about 6 to 8 months. High yielding variety maturing within 10 months. These changes affected the quality of stakes (planting material) obtained from these stems, which, in turn, affected yields of subsequent crops. 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. They can grow best in soil having ph, ranging between 5.5 to 6.5. It is the common means of planting cassava, sugar cane, cocoa, kola and coffee. In contrast, a maize plant which yields a cob with about 300 seeds However, the cultivation of cassava in the country is facing to viral diseases, particularly cassava mosaic disease (CMD) which can cause up to 95% yield losses. and tropical root crop. by the parasitoid Epidinocarsis lopezi). The nutritional content of cassava (Manihot esculenta Crantz) stems changed with different levels of soil fertility.These changes affected the quality of stakes (planting material) obtained from these stems, which, in turn, affected yields of subsequent crops. However, a deep and sandy, loamy soil is considered as the best suitable for producing optimum through growing cassava. You can cut a number of cuttings and place them down in layers. For controlling measure, learn the symptoms of all these mentioned diseases and operate a suitable treatment as sooner as they observed. All these are responsible for the healthy development of our body. Consuming cassava is also helpful in weight management. If you insert them in the ground vertically, you'll get one plant. A major industry constraint is the consistent supply of the desired volume and quality of raw materials for processing. Then they should be removed from the field though hand. Land preparation in growing cassava plays an important role in yield. 3. This was followed by another food security project from 1998–1999 to 2000–2001 which also incorporated postharvest technologies. They are resistant to drought, leaf spot, scale insect spider mite and mosaic diseases. Additionally, we have demonstrated that the survival ratio and plant growth are improved in comparison with general propagation in soil. Plant Pathology 54, 687-614. Eating cassava regularly prevents you from many types of cancer and also enhance the good digestive system. Cassava, also known as 'manihot', is the third largest source of carbohydrate in the human diet. 1.1. Container Planting. Origin and cultivation of cassava 1 1.2. So, let’s learn how to how to grow cassava commercially? CM6740-7 cassava cultivar from CIAT was used as planting material. (adsbygoogle = window.adsbygoogle || []).push({}); Cassava Farming – Guide & Tips and Profit, Cassava, one type of starchy tuberous bulb, a perennial tree grows in tropical and subtropical areas which are consumed by the people as a food. Planting material multiplication from sucker multiplication plots 31 8. The SAH involves the use of modified soil which holds plant roots in planting pots with little water. Particular attention should be given to training ... Cooter RJ, 2005. It's prized in Africa because there it tolerates long winter droughts and summer rains and it's these qualities that make Cassava an ideal choice for my Brisbane food garden. It is very convenient to use vegetative material from a previous crop to plant a new one. Cut a number of stems approximately 30cm long. This method is not only limiting in the numbers of planting materials but is also cumber-some, and labour intensive. Post-planting weed control According to, Application of Manure and Fertilizers in Cassava Farming. However, a deep and sandy, loamy soil is considered as the best suitable for producing optimum through growing cassava. Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Factors affecting quality of planting material in storage: Table 4 shows the effect of weather conditions, pest and diseases, duration of storage and the quality of stem cuttings on the quality of planting material in storage. The followings are the main disease, that is observed in the commercial production of Cassava. cassava. Options for planting material multiplication where quarantine diseases are present 30 6. Key words: In vitro. Plant your cut stem in the previously prepare did in the morning or evening in the cooler weather. Note that, in the organic-rich soil, tuber growth is less than the vegetative growth. Vertical or angular planting is recommended in areas of high rainfall Horizontal planting is better in dry areas. Cassava farming is mainly done to produce food items, solvents, alcohol, glucose, animal feed, energy, fertilizers, and some extra by-products. Jerry says, "It's these qualities that make cassava an ideal choice for my Brisbane food garden.".
