Rhizobium phaseoli inoculation trials on farmers' fields in Kenya.
(Univeristy of Nairobi, 1988)
A study was conducted on farmers' fields in Kikuyu Division, Kenya, to determine whether inoculating bean seeds with Rhizobium phaseoli could match the N supplied by 200 kg of diammonium phosphate (DAP) for pure stands of ...
Preliminary studies on some local materials for propagation media. 1. Physical and chemical properties.
(Univeristy of Nairobi, 1981)
Several materials for raising seedlings in containers before field transplanting were studied, namely coir dust, sawdust, coffee parchments, charcoal dust, local peat moss and sisal waste. Data are presented on their ...
Soil acidity components of tropical acid soils: their roles in determining lime requirement values and the effect of lime upon them.
(Univeristy of Nairobi, 1982)
Clay content, pH, organic matter content (%C), cation exchange capacity (CEC), exchangeable Al, exchangeable Mn, exchangeable acidity (ACe), residual acidity (ACr) and total acidity of 26 agricultural soils were determined. ...
Yield and quality of kale as affected by nitrogen side-dressing, spacing and supplementary irrigation.
(Univeristy of Nairobi, 1984)
In trials with the cv. Thousand Headed wide spacing (76 × 60 cm) increased mean fresh weight, branching and leaf production. Close spacing (76 × 30 cm) significantly increased total leaf yield/ha but decreased leaf:petiole ...
Effect of plant age on chamomile (Matricaria chamomilla L.) flower yield, essential oil content and composition
(Univeristy of Nairobi, 1989)
Seeds of a high-oil-yielding strain of M. chamomilla [Chamomilla recutita] were sown in a nursery and the seedlings were planted in the field 4 weeks after germination. Four rates each of P (0, 40, 80 and 120 kg P2O5/ha) ...
The Binding of Dietary Protein by Sorghum Tannins in the Digestive Tract of Pigs

Na+ AND Cl~ EFFLUXES AND IONIC REGULATION IN TILAPIA GRAHAMI, A FISH LIVING IN CONDITIONS OF EXTREME ALKALINITY
(1981)
The osmoregularity ability of the cichlid Tilapia grahami enables this fish to live
in conditions of extreme alkalinity (Reite, Maloiy & Aashaug, 1974; Maloiy et al.
1978). In this paper we describe the ionic balance of ...
