The situation is particularly dire for vegetatively propagated crops in many Sub-Saharan Africa countries. There has been less focus on tuber crops, legumes, and horticultural crops among the formal seed systems of SSA (Biemond et al. ). It had been noted that in many Southern African countries many commercial seed companies are not. Introduction. Cassava (Manihot esculenta) is a major staple food crop in many parts of the is particularly important in sub‐Saharan Africa, which currently accounts for c. 54% of total world production ().Important attributes of cassava are that it can be grown in a wide range of environments and withstands long periods of drought.

raised either from the seed or clone. Since, s vegetatively propagated clones began to replace seed propagation and probably reduced the genetic diversity within tea cultivation. In order to produce uniform crop with predetermined characters, vegetative propagation of superior clones are practiced.   A list of those crops that are entirely or mainly propagated vegetatively is given in Appendix 1. It is important that growers, economists, planners, administrators and occa- sionally even politicians appreciate that seed is the starting point for the produc- tion of many vegetable crops.

The aim is to tap maximum diversity in different crops (multi-crop collecting missions) occurring in the region to be explored, and maturing almost at the same time like maize, sorghum, pearl millet, rice, cowpea and mung bean during kharif (June/July - September/November); and wheat, barley, Brassicae, gram, peas and French bean during rabi season (October - March).

Cassava (Manihot esculenta Crantz.) is the most important vegetatively propagated food staple in Africa and a prominent industrial crop in Latin America and vegetative propagation through stem cuttings has many advantages, but deleteriously it means that pathogens are passed from one generation to the next and can easily accumulate, threatening cassava by: finance for agriculture, forestry and fisheries STATISTICAL ANNEX Notes on the annex tables Table A.1– Projected changes in crop yields due to climate change for all locations worldwide Table A.2 – Net emissions and removals from agriculture, forests and other land use in carbon dioxide equivalent, East African Highland bananas (EAHB) are triploid banana cultivars originating from the African Great Lakes region.

This chapter analyses the seed supply systems for vegetatively propagated crops in Kenya. Indata were collected from randomly and purposefully selected households, farmer groups and key informants in Central (Nyeri, Mukurwe-ini and Nkubu) and Eastern (Kitui, Matuu and Embu) regions, using sweetpotato as the study crop.

Management of viral diseases relies on the prevention measures. The current methods for many important crops, both those propagated by seed and those propagated vegetatively, will be outlined, describing the most up-to-date state of knowledge.

The chapters were written by experts who have been working for years with the respective crop(s). Examples of regional impact of this collaboration have been shown in Zambia and Malawi.

Introduction. The genus Mangifera belongs to the order Sapindales in the family Anacardiaceae, with more than 40 species. The effect on crop income on the adoption of Ejumula is likely to be related to the financial requirements for labor use in the production of sweetpotato.

Hired labor is one of the most expensive external inputs in the commercial production of vegetatively propagated crops. Results also show that, among the agroecology variables, farmers in.

A good start has been made, but many minor crops are not yet stored in base collections; and many duplicate base collections have yet to be identified or stored. Several institutes and programs have accepted responsibility for maintaining selected vegetatively propagated crops as field or.

Simply, profit margins for self-pollinated crops remain modest as once farmers obtain the novel germplasm, they can re-sow their own seed (Rubyogo et al.

Such institutions typically produce certified seed in centralized facilities. This figure is even lower for self pollinating (e.g., the common bean, groundnuts, rice), vegetatively propagated crops (e.g., potatoes, sweet potatoes, cassava), and crops with limited seed demand (e.g., indigenous vegetables, forages, open pollinated maize).

Therefore, improving the seed production ability (both in terms of quantity and quality) of Napier grass potentially conveys a multitude of.Seed is an essential input for crop production.

For farmers, access to affordable and high quality seeds is therefore important for increasing agricultural production and productivity.

In many developing countries, the formal seed system has shifted from a publicly dominated sector to a privately dominated sector. Nevertheless, the largest share of seeds are still produced by farmers themselves.
