Item Enhancing Sorghum Production and Marketing in Semi-Arid Kenya(Kenya Agricultural and Livestock Research Organization, 2014) Karanja, D.R.; Kisilu, R.K.; Kathuli, P.; Mutisya, D.L.; Njaimwe, A.N.; Keya, G.; Ouda, J.; Ayemba, J.; Kenya Agricultural and Livestock Research OrganizationSorghum is an important food security crop especially in semi-arid lands of Kenya. It is adapted in a wide ago-ecological zones. Sorghum requires less water than maize thus offering great potential for supplementing food and feed resources. Although sorghum varieties with a yield potential of 2 to 5t/ha are available, their productivity has remained low, at 0.7t/ ha. The major constraints to sorghum production are: inadequate soil moisture, low soil fertility, bird damage, pests and diseases, high cost of inputs, low adoption of improved varieties, weeds, lack of markets and limited utilization options. Farmers consider lack of markets, low producer prices and bird damage as the main constraints to increased sorghum production. Most sorghum is grown at altitudes of less than 1500 m above sea level. However there are varieties suitable for up to 2400 m a.s.l. It requires a rainfall of 250-400 mm during the growing season. Most dry land sorghum cultivars are those that thrive best in areas with a small range of diurnal temperatures i.e. the day and night temperatures do not differ greatly. Sorghum does best in wide range of soils including sandy, clay and loamy ones. It thrives well on fertile soils but will grow on somewhat exhausted soils.Item Kenya Agricultural Research Institute Annual Report 2002(Kenya Agricultural Research Institute, 2002) Kenya Agricultural Research Institute; Wangai, A.; Esilaba, A.; Nyongesa, D.; Miano, D.; Wasilwa, L.; Mwariri, M.; Kamoni, P.; Rege, R.; Ngatiri, V.; Ayemba, J.; Kenya Agricultural Research InstituteKARl continued to initiate activities that would actualise its 10-year strategy as envisaged in 2000. Key among these activities was the development of the 5-year Medium Term Plan III Guly 2003/4 to June 2007/8). This plan was set in the context of the Government's Poverty Reduction Strategy Paper for 2001-2004 and the Kenya Rural development Strategy 2002-2017. Several other events were held in the year, notably the inauguration of the Agricultural Research Week in collaboration with the Kenyan research fraternity and stakeholders in the agricultural industry. Through the research week KARI was availed an opportunity to invite interested parties to exhibit their agricultural technologies and products. The week was organized alongside the 8th KARI Biennial Scientific Conference under the theme Demanddriven agricultural research for sustainable natural resource base, food security and incomesItem Kenya Agricultural Research Institute Annual Report 2004(Kenya Agricultural Research Institute , 2004) Kenya Agricultural Research Institute ; Wangai, A.; Lukuyu, B.; Nyongesa, D.; Wasilwa, L.; Mwariri, M.; Rege, R.; Kimani, S.; Thuku, K.; Ayemba, J.; Ogutu, S.; Kenya Agricultural Research InstituteKARI activities for the year 2004 continued as guided by its 5-year Medium Term Plan III. The activities came at a time when the government launched the 10-year Strategy for Revitalizing Agriculture (SRA) as well as the 1st phase of the Kenya Agricultural Productivity Project (KAPP). It is expected that this will synergy the Government's Economic Recovery Strategy for Employment and Wealth Creation which has identified agriculture as the main productive sector and given it top priority.
