Productivity, profitability and partial nutrient balance in maize-based conventional and organic farming systems in Kenya Organic Eprints
Adamtey, Noah; Musyoka, Martha W.; Zundel, Christine; Cobo, Juan Guillermo; Karanja, Edward; Fiaboe, Komi K.M.; Muriuki, Anne; Mucheru-Muna, Monica; Vanlauwe, Bernard; Berset, Estelle; Messmer, Monika M.; Gattinger, Andreas; Bhullar, Gurbir S.; Cadisch, Georg; Fliessbach, Andreas; Mäder, Paul; Niggli, Urs; Forster, Dionys.
In 2007 two long-term trials were established in Kenya to contribute research-based evidence to the global debate on the productivity, economic viability and sustainability of different agricultural production systems. These trials compare conventional (Conv) and organic (Org) farming systems at high and low input levels at two locations, i.e. Chuka, with Humic Nitisols, high inherent soil fertility and rainfall, and Thika, with Rhodic Nitisols with low soil fertility and rainfall. The high input systems (High) represent commercial-scale, export-oriented production that uses the recommended amounts of fertilisers, pesticides and irrigation water to generate high yields, whilst the low input systems (Low) represent local smallholder practices, using...

Long-term performance of organic crop rotations in the tropics: First results from a high and a medium potential site in sub-humid Central Kenya Organic Eprints
Zundel, Christine; Schneider, Monika; Musyoka, Martha; Muriuki, Anne; Vanlauwe, Bernard; Mucheru-Muna, Monica; Chabi-Olaye, Adenirin; Niggli, Urs.
Organic Agriculture is perceived by many stakeholders as a promising approach to increase food security in developing countries. However, only few attempts have been made so far to assess agronomic and economic performance of Organic Agriculture in these regions in a systematic way. The Research Institute of Organic Agriculture (FiBL), together with its partners, is presently establishing long-term comparisons of farming systems in various agro-ecological and socio-economic contexts to study the different parameters that are essential for sustainable development. To date, three study areas have been selected: (a) a sub-humid area in Kenya where farming is subsistence-oriented; (b) a semi-arid area in India where cotton is produced for the export market;...

First season maize performance in a long-term farming systems comparison trial at KARI-Thika, Kenya Organic Eprints
Muriuki, Anne; Musyoka, Martha; Zundel, Christine; Schulthess, F; Mwangi, K.
Kenya’s smallholder farmers contribute 65% to total agricultural output in a predominantly mixed farming system where application of inorganic fertilizers and pesticides is minimal. By contrast, agriculture in developed temperate countries is dominated by large-scale farming and heavy reliance on fertilizers and pesticides to sustain high yields. Research conducted in temperate developed countries has shown that organic farming is superior to conventional farming in resource use efficiency, ecosystem functioning, soil fertility conservation and economic performance but results cannot be transferred directly to the tropics because of disparities in climate, soils and socio-economic environments. A long-term farming systems comparisons experiment was...

Resilience of Organic versus Conventional Farming Systems in Tropical Africa: The Kenyan Experience Organic Eprints
Muriuki, Anne; Musyoka, Martha; Fließbach, Andreas; Forster, Dionys.
In Kenya, agriculture is largely carried out by smallholder farmers, in a mixed farming noncommercialised setting where application of synthetic fertilisers and pesticides is minimal. Agricultural production is low and constrained by declining soil fertility, pest and diseases and increasingly unpredictable weather due to global warming. This calls for more resilient farming systems.
