Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya’s Central Highlands
(Springer Vienna, 2015-03)
Drier parts of Kenya’s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding ...
Growth Parameters of DK8031 Maize Variety as Affected by Varying Irrigation and Nitrogen Fertilizer Rates in Embu County, Kenya
(David Publishing, 2015)
Determination of crop growth parameters of maize helps assess the performance of the crop for food security. A study was
conducted in two seasons covering 2012 and 2013 to establish optimal irrigation and nitrogen fertilizer ...
Soil Organic Carbon and Nitrogen Fractions and Sugar Beet Sucrose Yield in Furrow-Irrigated Agroecosystems
(2015-03)
Soil organic matter (SOM) fractions were determined using extraction-,
incubation-, and density-based fractionation techniques on samples collected
from a range of furrow-irrigated sugar beet (Beta vulgaris L.) ...
Impact of reduced tillage and crop residue management on soil properties and crop yields in a long-term trial in western Kenya
(2015-11)
Sustainable farming practices are required to address the persistent problems of land degradation and declining crop productivity in sub-Saharan Africa (SSA). Approaches such as reducing tillage and retaining crop residues ...
Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya’s Central Highlands
(Springer, 2015-03)
Drier parts of Kenya’s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding ...
Potential side effects of biocontrol and plant-growth promoting Bacillus amyloliquefaciens bacteria on earthworms
(Elsevier, 2015-08)
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 ...
Rainfall Variability, Drought Characterization, and Efficacy of Rainfall Data Reconstruction: Case of Eastern Kenya
(Hindawi Publishing Corporation, 2015)
This study examined the extent of seasonal rainfall variability, drought occurrence, and the efficacy of interpolation techniques in eastern Kenya. Analyses of rainfall variability utilized rainfall anomaly index, coefficients ...
Applicability of conservation agriculture for climate change adaptation in Rwanda’s situation
(Academic Journals, 2015-09)
Improving food security and environmental conservation should be the main targets of innovative farming systems. Conservation agriculture (CA), based on minimum tillage, crop residue retention and crop rotations has been ...
Using Apsim-Model as A Decision-Support-Tool for Long-Term Integrated-Nitrogen-Management and Maize productivity under Semi-Arid Conditions in Kenya
(Cambridge University Press, 2015-04)
There is continued decline in per capita agricultural productivity in the drier parts of Kenya’s central highlands. The declines have been linked to low and declining soil fertility, soil water, high atmospheric heat, ...
