It's Cassava also known as 'manihot' and it's humanity's third largest source of carbohydrate. Just boil or steam the leaves for 2 minutes and they're perfectly safe to eat.". 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. The nature of the in vitro propagation system used to produce regenerated plants can have a profound effect ... the epigenetic fidelity of meristem micropropagation and to seek specific methylation signatures associated to in vitro propagation in cassava ... Materials and Methods Plant Material. Rapid multiplication technique can be used to produce large quantities of cassava stems as planting materials for subsequent seasons. A STRATEGY FOR MAINTAINING AND SANITIZING CASSAVA PLANTING MATERIAL IN WEST AFRICA P. Bieler and J. S. Yaninek* Abstract A significant constraint to cassava production in West Africa is the use of planting material that is insufficiently vigorous and is infested with pests and diseases. A major industry constraint is the consistent supply of the desired volume and quality of raw materials for processing. Planting is fairly simple. For improved variety, it is a good idea to add farmyard manure, more than 20 tonnes per hectare along with proper chemical fertilizers. Autumn is the time to propagate cassava and it's very easy to grow, using cuttings of old, mature brown wood. So, grow this crop in a soil having good organic content with proper drainage to obtain a higher yield from it. You can use any part of the cassava stem as propagating material. Land preparation in growing cassava plays an important role in yield. Cassava also helps in treating diarrhea, and the rheumatic diseases. This crop is very prone to the frost condition so try to grow cassava in a frost free area in a warmer region with moderate humid conditions. The SAH involves the use of modified soil which holds plant roots in planting pots with little water. The agronomic success of any crop depends fundamentally on the quality of the propagation material used for the crop establishment. Varieties and planting material . Yield of cassava 3 1.4. List of main cassava diseases 34 10. Vertical or angular planting is recommended in areas of high rainfall Horizontal planting is better in dry areas. 2009). These three methods are listed below: This method of plantation should opt for growing cassava in the monsoon to avoid the constant wetting of the rot. propagation, cassava, nodal segments. Germplasm collection and selection 5 1.6. Introduction . In addition, cassava stem cuttings are perishable, bulky and cumbersome to transport, and require considerable storage space. With vegetatively propagated crops, diseases and pests can build up over several generations of propagation, a problem that is negligible with botanic seeds.
