Non-genetic causes of the heterogeneity of variance in milk yield among Holstein-Friesian Herds in Kenya.
(AJOL, 2005)
Lactation records of Holstein- Friesian cows in Kenya made during the period 1968 to 1984 were analyzed for the cases of heterogeneity of variance in milk yield among herds using a fixed effect least squares model. Year, ...
Effect of pH and magnesium on colour development and anthocyanin accumulation in tuberose florets
(African Crop Science Conference Proceedings, Vol. 9. pp. 227 - 234, 2009)
Anthocyanins are a group of plant pigments responsible for colors ranging from red to violet and blue. Anthocyanins are
pigments that accumulate in the vacuoles of plant epidermal cells. Chroma and hue are dependent on ...

Induced male-sterility alters dry matter distribution in solanum villosum mill.
(ISHS, 2008)
African nightshades are leafy vegetables popular in Africa and South-East Asia for their high nutritional and medicinal value. The plants are strongly autogamic, exhibiting early and excessive flowering coupled with prolific ...
Scope for genetic enhancement of the parasitisation potential of four native strains of Trichogrammatoidea sp. nr. lutea Girault (Hymenoptera: Trichogrammatidae) in Kenya
(Taylor & Francis, 2007-09-14)
In response to emerging interest in commercial mass production of Trichogramma for Helicoverpa armigera biocontrol in eastern Africa, laboratory experiments were undertaken to assess the scope for genetic enhancement of ...
Effects of Acid Scarification, Priming with PEG, NaCI or Sea Water as Osmoticum and Dehydration on Spinach Seed Germination at 30°C
(Japanese Society for Horticultural Science, 2005)
Spinach (Spinacia oleracea L.) seeds were scarified with an 18 N H2S04 solution, then primed for one week at 10De in PEG- 6000, NaCl or natural sea water. Germination tests were carried out
at 30De, which is normally ...
Scaling up production of traditional green leafy vegetables in Kenya: Perspectives on water and nitrogen management
(Global Science Books, 2007)
Traditional green leafy vegetables are promising alternative vegetable crops consumed in Kenya and other African countries. The crops whose consumption is on the increase include vegetable amaranth (Amaranthus spp.), African ...
