Internal parasitism in milk goats in Kenya.
(University of Nairobi, 1884)Observations were made on individual cases and on herds showing the effects of internal parasitism on the health and productivity of Toggenberg and Saanan goats. The clinical reactions varied markedly, being influenced by ... -
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 ... -
Effects of weeding and row spacing on sugar cane at the Kenya coast.
(University of Nairobi, 1981)Using the sugar cane cultivar Co 421, competition from weeds for the whole growing season was compared at three row spacings with competition for periods ranging from 15 to 120 days at the start of the season or later and ... -
Mixed cropping of maize and beans in Kenya: results of the bean general culture trials in 1975 and 1976.
(2015-10-09)In 4 trials in 1975-6, beans [Phaseolus vulgaris] intercropped with maize did not decrease maize grain yields significantly compared with pure stands at sites in W. Kenya, but in 1 of 3 trials in E. Kenya intercropped maize ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
The effect of time of planting on four bean (Phaseolus vulgaris) genotypes in Kenya.
(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 ... -
Changes in Testicular Leydig Cells and in Plasma Testosterone Levels Among Seasonally Breeding Rock Hyrax
(University of Nairobi, 1973-05)Seasonal changes in plasma testosterone levels and in various testicular parameters were studied in 41 adult male rock hyrax (Procavia habessinica). Among animals collected during the annual breeding season, testis weights ... -
Comparative Observations on Intertubular Lymphatics and the Organization of the Interstitial Tissue of the Mammalian Testis
(University of Nairobi, 1973-12)The interstitial tissue of the testis has been studied in some 14 mammalian species and compared with respect to the abundance of Leydig cells and loose connective tissue, the degree of development and location of the ... -
Relationship between blood levels of testosterone and accessory sex gland weights in impala (Aepyceros melampus)
(University of Nairobi, 1972-08)1. In twenty-two male impala, plasma testosterone levels have been compared with weights of seminal vesicles and bulbourethral glands. 2. The results show that single measurements of circulating testosterone are ... -
Large scale maize production in Ghana.
(University of Nairobi, 1973)Technical information on large-scale maize production in Ghana is summarized. Information on land-use policy, varieties, land clearing, soil conservation, land preparation, seeds and sowing, fertilizers, weed control, pests ... -
Zero tillage.
(University of Nairobi, 1975)The effects of different cultivation systems on soil OM content, soil erosion, soil moisture and cover crops are reviewed. It was concluded that although minimum cultivation has advantages over conventional systems in soil ... -
Pruning and trellising purple passion fruit. II. Disease incidence, fruit size and quality.
(University of Nairobi, 1980)Trellising did not affect fruit size or quality. Three-wire trellising produced more diseased [Alternaria passiflorae] laterals and fruit than 1-wire trellising. Light and selective pruning produced heavier and better ... -
Pruning and trellising purple passion fruit. I. Yields and seasonal trends.
(University of Nairobi, 1980)In an experiment in which one-wire and 3-wire trellising as well as severe, selective, light and no pruning were compared, it was found that pruning did not increase yields or reduce the usual decline in yield over a 3-year ... -
Potential side effects of biocontrol and plant-growth promoting bacillus amyloliquefaciens bacteria on earthworms.
(University of Nairobi, 2015)Many bacteria strains are now successfully used for plant-growth promotion (PGPR) and as biocontrol agents (BCA) against plant diseases. Mechanisms behind their action involve production of enzymes and antibiotics, which ... -
