List of main cassava diseases 34 10. 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 In-vitro regeneration of cassava 6 1.6.2.1. material (starch, chips, pellets, unfermented flour etc). Planting material multiplication from fields in production 31 7. Tissue Cultured Planting Material Tissue cultured cassava planting material at the in vitro multiplication stage Tissue culture cassava plantlets hardened and ready for planting Plantlets generated by the tissue culture method will provide a large quantity of clean (i.e. The multiplication ratio is the increase in planting material over what has been planted. 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. For controlling all these, try to keep away all these mentioned. Plants are usually started from propagules made from parts of mature stems (much like propagating potatoes). Particular attention should be given to training ... Cooter RJ, 2005. Options for planting material multiplication where quarantine diseases are present 30 6. Planting material multiplication from fields in production 31 7. Cassava (Manihot esculentaCrantz.) Scientists working on cassava breeding are now using the Semi-Autotrophic Hydroponics (SAH) technology to rev up the propagation of clean cassava planting materials. It is the common means of planting cassava, sugar cane, cocoa, kola and coffee. Cassava can be grown in many types of soil, producing even in poor soil but but will be optimally productive in well-draining, sandy clay loam with a pH between 5.5 and 6.5. Plant them at a distance one meter apart. Propagation and regeneration 6 1.6.1. 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. In Israel, as a result of planting virus-tested material, yields increased at least by 100%, while in China increases ranged between 22% and 92%. Commercially available nutrients were used in order to substitute the propagation media components. • Seeds used for propagation are also valuable food for man. Given the vegetative propagation method used for cassava, availability of clean planting material for propagation is a major constraint, since white flies and infested planting material transmit the disease. कसावा, Sakarkand (India, Hindi), ات کٹ (Urdu), 木薯 (Chinese),  Tarul (Nepali), Cassave (Dutch), Maniok (German), Moxog (Somali), كاسافا (Arabic), 樹薯 (Taiwanese), Kamoteng Kahoy (Cebuano), 카사바  (Korean), มันสำปะหลัง (Thai), Maniok jadalny (Polish), маниока (Macedonian), Маниока (Bulgarian), тропска биљка(Serbian), Kamoteng kahoy (Filipino), Mandi’o (Estonian), Maniok (Bosnian), Casabhaigh (Irish), Manyok or Mandioko (Turkish), Mandioca (Portuguese), Yuca (Spanish), Sắn(Vietnamese), Manihot esculenta (Italian), مانیوک (Persian), Маниок (Russian), Manioka (Latvian), キャッサバ (Japanese),  Maniok (Norwegian),Manyokka (Sinhalese), Manioc (French), Tapioca (Czech), Maniok (Slovak), 木薯 (Cantonese), Maniok (Swedish), Ubi kayu (Malay), Kassava (Danish), Mogo (Gujarati). plays a vital role in the production. Planting material multiplication from sucker multiplication plots 31 8. Cassava is also used as home remedy for curing headaches and fever. Roots of this commercial crops are mainly consumed because of these are an excellent source of starch along with vitamin ‘C’, calcium, phosphorus, etc. A major difference with respect to conventional propagation by stakes is that in vitro technology reduces or abolishes spreading diseases causal agents, though the sanitary quality of planting material must always be verified before starting an in vitro multiplication program. Utilisation of cassava 2 1.3. Cassava, also known as 'manihot', is the third largest source of carbohydrate in the human diet. The optimal cassava plant spacing is 1 meter by 1 meter apart along each row and across ridges or mounds.. To maintaining the moisture content on your farm, this planting method should be opted for growing in summer or hotter days. The major genetic factor that determines quality of roots is dry matter content. They contain cyanide compounds. The yield of this commercial crop depends on numbers of key factors such as theagro-climaticc condition, type of soil, the cultivar or variety is chosen for its cultivation along with good farm management skills. However, harvesting at the right time helps in obtaining the best quality of tubers in a higher amount. Basically, they have originated from South Africa and the scientific name of cassava is Manihot esculenta. Root production is maximized when temperatures are between 25 and 32°C (77–90°F). With the aim of transferring micropropagation techniques to cassava seed producers, a simple and lowcost medium for in vitro micropropagation was developed. The plant is usually cultivated through vegetative propagation, but cassava’s vegetative propagation is a mixed blessing (Thro et al., 1999). Rapid multiplication technique can be used to produce large quantities of cassava stems as planting materials for subsequent seasons. Summary table of standards 39 11. in the following article. Cassava is a staple food for over 800 million people globally providing a cheap source of carbohydrate. Rapid multiplication of cassava stem cuttings as planting material involves producing cassava stems using 2 to 3 node cassava stakes. The SAH involves the use of modified soil which holds plant roots in planting pots with little water. It is essential to provide water in sufficient amount to maintain the moisture content in your soil for the first month of the plantation so that grafted cuts set a well on the field and also to grow healthy tubers. Autumn time is propagation time for Cassava and it's really easy to grow. Plant your cut stem in the previously prepare did in the morning or evening in the cooler weather. Consuming cassava frequently is also beneficial for good nerve and brain health. CM6740-7 cassava cultivar from CIAT was used as planting material. 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. It is helpful in boosting the immune system and lowering the blood pressure. 35000 planting material used in the propagation of cassava between 5.5 to 6.5: this unassuming plant is in fact,...
