Adoption of Drought Tolerant Sorghum in Western Kenya
Ouma, Evans Ochieng; Kisinyo, Peter; Gudu, Samuel; Mugalavai, Violet; Nyangweso, Peter; Onkware, Augustino (Moi University Press, 2012)Food and nutritional insecurity are responsible for poverty and low livelihoods of about 33% of people living in western part of Kenya. This is against MDG1. The production of sorghum which is a staple food crop is below ... -
Aluminum tolerance mechanisms in Kenyan maize germplasm are independent from the citrate transporter ZmMATE1
Matonye, Thomas K.; Gudu, Samuel; Kisinyo, Peter; Matonye, Thomas K.; Barros, Beatriz A.; Ouma, Evans Ochieng; Cheprot, Reuben K.; Apolinário, Leandro C.; Ligeyo, Dickson O.; Costa, Marcella B. R.; Were, Beatrice Ang’iyo; Onkware, Augustino; Noda, Roberto W.; Magalhaes, Jurandir V.; Guimaraes, Claudia T. (Scientific Reports, 2020) -
Development of maize single cross hybrids for tolerance to low phosphorus
Gudu, Samuel; Kisinyo, Peter; Ouma, Evans Ochieng; Ligeyo, Dickson; Matonyei, Thomas; Were, Beatrice Ang’iyo; Agalo, Joyce; Too, Emily; Onkware, Augustino; Okalebo, John; Othieno, Caleb (2015-08-21)Low available phosphorus (P) is one of the major hindrances to maize (Zea mays L.) productivity in acid soils. The objectives of this study were to: (1) develop P-efficient maize inbred lines, (2) develop single cross ... -
Enhancing Maize Grain Yield in Acid Soils of Western Kenya Using Aluminium Tolerant Germplasm
Ouma, Evans Ochieng; Ligeyo, Dickson; Matonyei, Thomas; Agalo, Joyce; Were, Beatrice Ang’iyo; Too, Emily; Onkware, Augustino; Gudu, Samuel; Kisinyo, Peter; Nyangweso, Philip (2015-07-21)Abstract: Maize (Zea mays L.) is one of the world’s most important cereals and is a staple food for many people in developing countries. However, in acid soils (pH < 5.5), its productivity is limited by aluminium (Al) ... -
Evaluating Heritability and Relationships among Phosphorus Efficiency Traits in Maize under Low P Soils of Western Kenya
Ouma, Evans Ochieng (Current Journal of Applied Science and Technology, 2021-03-15)Low available phosphorus (P) remains a major limitation to maize (Zea mays L.) productivity across the world. Selection for P efficiency is key as part of strategies to achieving agricultural sustainability. The objectives ... -
Genetic Effects for Maize P Efficiency Traits in Acid and Non-acid Soils of Western Kenya
Ouma, Evans Ochieng; Gudu, Samuel (American Journal of Experimental Agriculture, 2015)Soil acidity is a major constraint to maize (Zea mays L.) productivity in tropical soils due to toxic levels of aluminium (Al) and phosphorus (P) deficiency. The objectives of this study were ... -
Immediate and residual effects of lime and phosphorus fertilizer on soil acidity and maize production in western Kenya
Kisinyo, Peter; Othieno, Caleb; Gudu, Samuel; Okalebo, J. R; Opala, P. A.; Ng'etich, W. K.; Nyambati, R.O.; Ouma, Evans Ochieng; Agalo, Jerry; Kebeney, S.J; Too, E.J; Kisinyo, Joyce; Opile, W.R. (2015-08-21)Soil acidity and phosphorus (P) deficiency are some of the major causes of low maize yields in Kenya. This study determined the immediate and residual effects of lime and P fertilizer on soil pH, exchangeable aluminium ... -
Inheritance of maize phosphorus efficiency in acid soils of western Kenya
Ouma, Evans Ochieng (International Journal of Information Research, 2016-04)Soil acidity is a major constraint to maize (Zea mays L.) productivity in tropical soils due to toxic levels of aluminium (Al) and phosphorus (P) deficiency.Selection for acid-soil tolerance is a sustainable way for ... -
Micro-Dosing of Lime, Phosphorus and Nitrogen Fertilizers Effect on Maize Performance on an Acid Soil in Kenya
Kisinyo, Peter; Gudu, Samuel; Palapala, Valerie; Opala, P. A.; Othieno, Caleb; Ouma, Evans Ochieng (Sustainable Agriculture Research, 2015-03-17)High cost of inorganic fertilizers and lime has precluded their use by smallholder farmers to remedy the problem of soil acidity and infertility in Kenya. To address the problem, we tested a precision technique referred ... -
