Relationship of maize yields to seasonal water balance at the Katumani Experimental Station

Fisher, NM (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 ...

Mixed cropping research at Kabete

Fisher, NM (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. ...

Studies in mixed cropping. 2. Population pressures in maize-bean mixtures.

Fisher, NM (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 ...

Studies in mixed cropping. 1. Seasonal differences in relative productivity of crop mixtures and pure stands in the Kenya Highlands.

Fisher, NM (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 ...

The effect of time of planting on four bean (Phaseolus vulgaris) genotypes in Kenya.

Fisher, NM (University of Nairobi, 1980)

4 P. vulgaris genotypes were compared at 3 sowing dates during 1 season (April-June 1976) and 4 sowing dates during a 2nd season (Nov. 1976-Jan. 1977). Yield declined with delay in sowing in both seasons, but in the 2nd ...
