Evaluation of different improved upland rice varieties for low soil nitrogen adaptability
(2015)Scarcity of nitrogen fertilizer is a major constraint to rice production particularly in developing countries. Low soil fertility prevalent in farmer's fields has led to low rice yields and the ever escalating fertilizer ... -
Physiological and biochemical responses of five nerica rice varieties (Oryza sativa L.) to water deficit at vegetative and reproductive stage
(2012)Food shortage is a major problem in sub Saharan Africa as population increases. Over 89% of Kenyans are food poor and are malnourished especially in rural areas. NERICA (New Rice for Africa) are high yielding rainfed ... -
Effects of water deficit on days to maturity and yield of three NERICA rainfed rice varieties
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Effects of water deficit on physiology and morphology of three varieties of nerica rainfed rice (Oryza sativa L.)
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Chlorophyll fluorescence, protein and chlorophyll content of three nerica rainfed rice varieties under varying irrigation regimes
(2010)Water deficit affects growth and development of rainfed rice leading to a considerable yield reduction or crop failure. Although the rice crop is susceptible to water deficit, there is a marked genotypic variation in ... -
An analysis of the market POA case of Rachuonyo South
(2013)Despite the potential of sweet pot poverty reduction through incom growing regions still live below poverty index of 77% producing areas in Kenya. Thus, with the view of determining if monopoly powers to their advanta ... -
Determinants of demand for sweet potatoes at the farm, retail and wholesale markets in Kenya
(Horizon Research Publishing, 2013-09)Despite the potential of sweet potato in helping to meet Kenya's food needs and poverty reduction through income generation, detailed information on sweet potato demand relations is unavailable to enable the traders ... -
Genetic and phenotypic parameters for feed efficiency in indigenous chicken in Kenya
(Elsevier, 2018-01-01)This study aims to determine the genetic and phenotypic parameters of net feed efficiency (NFE) traits namely Residual feed intake (RFI), residual gain (RG), and residual intake and gain (RIG) along the growth curve ... -
Effect of sequential teaching methods on retention of knowledge in Biology by secondary schools students in Kenya in Kenya
(2017-05-11)Despite the importance of knowledge in Biology, candidates' performance at the national examination, The Kenya Certificate of Secondary Education (KCSE) is poor. This could be attributed to the teaching methods. The ... -
Genome-wide association analysis of residual feed intake and milk yield in dairy goats
(Oxford University Press, 2016-10-01)Interest in both dairy and meat goat production in the US has been increasing, and there is tremendous opportunity for genetic progress in traits that are easy to measure (eg, milk yield) and those that are more difficult ... -
Non-genetic sources of variation and temporal variability in growth and feed efficiency traits among phylogenetically distinct clusters of indigenous chicken in Kenya
(Springer Netherlands, 2016-12-01)This study aims to investigate the influence of non-genetic factors on feed efficiency in indigenous chicken. Residual feed intake (RFI), residual gain (RG) and residual intake and gain (RIG) were used as measures of ... -
Dairy production systems and the adoption of genetic and breeding technologies in Tanzania, Kenya, India and Nicaragua
(Cambridge University Press, 2016-12)Summary Development of the livestock industry and its role in poverty alleviation in developing countries depends on how adaptive the production systems are to changing global environmental and economic trends. This ...
