Influence of seedling age and nitrogen application method on dry matter production and nitrogen uptake of lowland rice cultivated on an Alfisol.
(Univeristy of Nairobi, 1992)
In a field experiment during the long and short rainy seasons in 1987 at Ibadan, Nigeria, rice cv. IITA 212 DM production was not affected by transplanting 21-, 31- or 41-d-old seedlings. Placement of 60 kg N/ha at 5-10 ...

(Univeristy of Nairobi, 1990)
In a field experiment in 1985/86 at the Kabele Field Station (alt. 1940 m a.s.l) B. oleracea var. acephala cultivars Thousand Headed (kale) and Georgia (collard) received 0, 47, 94 or 188 kg N/ha. Petiole and, more ...
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 ...
Effect of nitrogen and variety on essential-oil yield and composition from chamomile flowers.
(Univeristy of Nairobi, 1992)
The effects of N (0, 75, 150 or 225 mg/2.7 litre pot) on the essential oil content and composition of the flowers of 2 Matricaria chamomilla [Chamomilla recutita] cultivars were investigated. N (up to 150 mg/pot) significantly ...
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) ...
