Studies in mixed cropping. 3. Further results with maize-bean mixtures.
(University of Nairobi, 1974)
In contrast to earlier results, a clear advantage from mixed cropping of maize and beans (Phaseolus vulgaris) was found in the long-rain seasons (March-Sept.) of l976 and l977. Pure stand yields were low due to drought in ...
Studies in mixed cropping. 1. Seasonal differences in relative productivity of crop mixtures and pure stands in the Kenya Highlands.
(University of Nairobi, 1977)
In a trial during 4 cropping seasons in 1972-4 at Kabete, yields of maize/bean (Phaseolus vulgaris) and maize/potato mixtures grown in alternate rows were compared with pure stands of the component species. In seasons with ...
Mixed cropping research at Kabete
(University of Nairobi, 1975)
In field trials in 1972-4, maize cv. Katumani Composite B in the short rainy season and Hybrid 511 in the long rainy season were grown in pure stands or in mixture with potatoes or with beans (Phaseolus vulgaris) cv. ...
Relationship of maize yields to seasonal water balance at the Katumani Experimental Station
(University of Nairobi, 1975)
Data for 10 years cultivation of rain-fed maize showed that crops failed when rainfall was equivalent to <54% of potential evapotranspiration and that with rainfall equivalent to >62%, grain yield was not related to available ...
Studies in mixed cropping. 2. Population pressures in maize-bean mixtures.
(University of Nairobi, 1977)
In a trial in the long-rains season of 1974, maize/bean (Phaseolus vulgaris) mixtures and pure stands of each crop sown at low, medium or high plant densities were compared. Grain/seed yields of maize and beans in pure ...
The water requirements of high density coffee: 1. Responses to irrigation and plant water stress measurements.
(University of Nairobi, 1978)
Coffee trees spaced at 5000 or 6667/ha received the following irrigation treatments: no irrigation; irrigation every 2 or every 8 weeks; April-June; July-September; October-December; or January-March. The effects of these ...
