Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)
Invasive plant species when introduced into new environments may result into a number of
ecological problems (Howard et al., 2000). They may influence other species through
pathways such as allelopathy or phytotoxicity ...
Bacteriological and Physicochemical characterisation of AoraLoko Stream water,Maseno kenya
(AESS Publications, 2017)
Safety and quality of drinking water is an important aspect in public health. Water
pollution is one main cause of worldwide diseases and death. Human activities around
water catchment areas contribute to some level ...
New evaluation of Alternaria brassicicola isolates against Striga hermonthica seeds emergence on maize in Kenya
(JRWS, 2021)
Striga hermonthica (Del.) Benth is also known as witchweed, is a highly noxious parasite
of cereal in Sub- Saharan Africa leading to enormous economic losses of above 7 billion
US$ yearly. Some of the suggested control ...
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 ...
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 ...

A ten-year study of Retinoblastoma in Uganda: An approach to improving outcome with limited resources
(Elsevier, 2021)
Survival of children with cancer in resource-limited regions is very poor compared to better-resourced regions. Retinoblastoma (RB) is a childhood cancer that is commonly reported in many regions of Africa. RB may be safely ...
Stem bark extracts of Erythrina excelsa (Baker) and their biological activities
(2016)
The species is known from Southern Nyanza, Migori in Kenya. The extraction of the stem bark was done
sequentially using organic solvents starting with the least polar; n-hexane then dichloromethane, ethyl
acetate and ...
Sorghum is an important staple food crop in Kenya, but its yield is low due to many constraints which include diseases, drought, soil fertility, and pests, notably parasitic weed Striga hermonthica. Twenty elite sorghum genotypes and one resistant check were evaluated in three replications in a complete randomized design in Agar Gel (AG) experiment and randomized complete block design on selected Striga hotspot farms at Kadel and Nyahera in western Kenya. Significant differences (p<0.001) were realized both in the fields (plant height, dry shoot biomass yield, grain yield, field Striga count, and Striga damage ratings) and in the AG experiment with respect to maximum germination distance and numbers of induced germinated Striga seeds. Among the sorghum genotypes evaluated under field conditions, T53B, N57, N68, C26, IESV 92036-SH, T30B, and Uyoma 47 White genotypes had stable yields under Striga infestation in the two sites, whereas Nyadundo 1, Nyadundo 2, and Uyoma 8 were susceptible. In the AG experiment, E117B, T30B, Uyoma 8, Uyoma 42 STR, and T53B induced high numbers of germinated Striga seeds with maximum germination distances (MGD). In contrast, Uyoma 47 Brown, IESV 92038/2-SH, and IESV 92036-SH sorghum genotypes secreted low amounts of SLS suggesting resistance. This study has identified and selected four Striga tolerant (T53B, N68, N57, and T 30B) and resistant (C 26, Uyoma 47 Brown, IESV 92038/2-SH, and IESV 92036- SH) sorghum genotypes which can be utilized in further research programs or adopted to improve sorghum productivity in the highly Striga infested regions of western Kenya.
