Genetic diversity of symbiotic bacteria nodulating common bean (Phaseolus vulgaris) in western Kenya
(Public Library of Science, 2018-11-15)Biological nitrogen fixation (BNF) in legumes plays a critical role in improving soil fertility. Despite this vital role, there is limited information on the genetic diversity and BNF of bacteria nodulating common bean ... -
Response of Sorghum (Sorghum bicolor (L.) Munch) and Chemical Characteristics of Soil to Organic and Inorganic Fertilizers on Kenyan Lower Midlands Acid Soil
(International Journal of Plant & Soil Science, 2019-05-17)Soil acidity, low level of nitrogen (N), phosphorus (P) and soil organic matter are major constraints to sorghum production in Kenya. We investigated the effect of farmyard manure (FYM) and combined application of inorganic ... -
NITROGEN SOURCES AND THEIR EFFECTS ON NITROUS OXIDE EMISSION AND MAIZE YIELD IN WESTERN KENYA.
(2019-09-01)This study assessed the effect of applying inorganic or organic sources of nitrogen, or their combination, on N2O emission, maize yield and Nitrogen Use Efficiency (NUE) at Nyakach, a lowland and Soin, a highland in western ... -
Evaluation of crop arrangement and phosphorus rate on performance of maize-common bean intercropping in western Kenya
(Archives of Agriculture and Environmental Science, 2020)The effect of phosphorus (P) rate and crop arrangement on the performance of component crops in maize-bean intercropping systems was investigated at two sites; Malanga and Bugeng’i in western Kenya. A split plot design ... -
Response of soybean (Glycine max L.) to application of lime and phosphate fertilizer in an acid soil of western Kenya
(Research gate, 2020)The effect of combining lime and phosphate fertilizer on the performance of soybean (Glycine max L.) was investigated in a pot experiment consisting of nine treatments of three rates of lime (0, 4 and 8 t ha−1) in a ... -
Novel sources of resistance to blast disease in finger millet
(2020)Finger millet (Eleusine coracana (L.) Gaertn. subsp. coracana) is the most important millet in eastern Africa and perhaps the oldest domesticated cereal grain in Africa. One of the major factors limiting finger millet ... -
Recent advances in the use of Tithonia diversifolia green manure for soil fertility management in Africa: A review
(Agricultural Research Communication Centre, 2020)Tithonia biomass transfer was presented as a technology that would replenish infertile soils, enhance food security and eradicate poverty in Africa in the 1990s. Since then, a huge volume of research has been conducted ... -
Influence of plant density and nitrogen application on growth and quality of sweet pepper (capsicum annuum) in Uasin Gishu county
(Research Gate, 2020)Sweet pepper an important export in Uasin Gishu had been facing a problem of rejection at the international market due to failure to meet the specified quality standards. The field experiment was conducted during the ... -
Response of soybean (Glycine max L.) to application of lime and phosphate fertilizer in an acid soil of western Kenya
(Archives of Agriculture and Environmental Science, 2020)The effect of combining lime and phosphate fertilizer on the performance of soybean (Glycine max L.) was investigated in a pot experiment consisting of nine treatments of three rates of lime (0, 4 and 8 t ha−1) in a factorial ... -
Depletion of phosphate rock reserves and world food crisis: Reality or hoax?
(African Journal of Agricultural Research, 2020)Phosphate rock (PR) deposits are the major source of phosphate (P) fertilizers for soil fertility replenishment. The demand for P fertilizers in the year 2014 was 42,706,000 tons and was expected to reach 46,648,000 tons ... -
Effects of Vermicompost, Tithonia Green Manure and Urea on Quality of Swiss Chard (Beta Vulgaris L. Var. Cicla L.) in Kenya
(Canadian Center of Science and Education, 2021)Swiss chard (Beta vulgaris L. var. cicla) is a popular vegetable because it is nutritious, robust, easy to grow. It requires regular applications of nitrogen, which causes accumulation of oxalates and nitrates within the ... -

Promoting Conservation Agriculture through Push-Pull Technology as an Agroecological Transition
(Maseno University, 2023)Low soil fertility, weeds, pests, and climatic change severely threaten crop productivity and agricultural sustainability, especially in SSA. Despite decades of research finding adequate technical solutions for most ... -
The use of phosphate rocks in East Africa: A review
(Indian journals, 2023-04-06)The use of locally available phosphate rock (PR) has often been proposed as a cheaper alternative to the more expensive superphosphate fertilizers to alleviate severe phosphorus deficiencies that threaten food security in ... -
Soil Acidity and Liming Handbook for Kenya
(Research gate, 2023-07)Soil acidity develops from a combination of natural and anthropogenic processes. Its effects can be evaluated through its impact on soil’s physical, chemical, and biological activities that ultimately affect nutrient ... -
