Aguk, J.A.Karanja, N.Schulte-Geldermann, ElmarJefwa, J.M.Kinyua, Z.M.[Evaluating arbuscular mycorrhizal fungi (amf) and phosphate solubilizing bacteria (psb) inoculants on performance of potato (Solanum tuberosum).]Evaluating arbuscular mycorrhizal fungi (amf) and phosphate solubilizing bacteria (psb) inoculants on performance of potato (Solanum tuberosum).

Even though potato (Solanum tuberosum L.)-based intercropping systems are widely practised in developing countries, only a few studies have focused on legumes as the companion intercrops. This study was conducted to assess the effect of incorporating legumes into the potato production system on g...


Gitari, H.I.Gachene, C.K.K.Kamau, S.Nyawade, S.Sharma, K.Schulte-Geldermann, ElmarKaranja, N.[Optimizing yield and economic returns of rain-fed potato (Solanum tuberosum L.) through water conservation under potato-legume intercropping systems.]Optimizing yield and economic returns of rain-fed potato (Solanum tuberosum L.) through water conservation under potato-legume intercropping systems.

Soil erosion rates are exacerbated in sloping arable lands of Central Kenya due mainly to the high soil disturbance caused by potato hilling. A field study was conducted in runoff plots to quantify the effect of potato hilling on soil loss, soil moisture distribution and soil temperature. Three h...


Nyawade, S.Karanja, N.Gachene, C.K.K.Schulte-Geldermann, ElmarParker, M.[Effect of potato hilling on soil temperature, soil moisture distribution and sediment yield on a sloping terrain]Effect of potato hilling on soil temperature, soil moisture distribution and sediment yield on a sloping terrain

Competition for nitrogen (N) and phosphorous (P) under potato-based intercropping systems decreases the level of nutrients available for potato and subsequently influences nitrogen and phosphorous use efficiency. A field trial was conducted for four consecutive seasons between 2014 short rains an...


Gitari, H.I.Karanja, N.Gachene, C.K.K.Kamau, S.Sharma, K.Schulte-Geldermann, Elmar[Nitrogen and phosphorous uptake by potato (Solanum tuberosum L.) and their use efficiency under potato-legume intercropping systems]Nitrogen and phosphorous uptake by potato (Solanum tuberosum L.) and their use efficiency under potato-legume intercropping systems

Bacterial wilt disease, race 3 biovar 2A, is a devastating disease of potato and other important solanaceous crops, with no chemical control method. The current studies were, therefore, undertaken to assess the efficacy of biocontrol agent (BCA) and organic amendments to manage bacterial wilt (BW...


Aguk, J.A.Karanja, N.Schulte-Geldermann, ElmarBruns, C.Kinyua, Z.Parker, M.[Control of bacterial wilt (Ralstonia solanacearum) in potato (Solanum tuberosum) using rhizobacteria and arbuscular mycorrhiza fungi.]Control of bacterial wilt (Ralstonia solanacearum) in potato (Solanum tuberosum) using rhizobacteria and arbuscular mycorrhiza fungi.

Soil organic matter (SOM) losses due to soil erosion may be considered low in continuous potato (Solanum tuberosum L.) cropping systems, but cumulated over time may cause considerable soil degradation. A field study was conducted in Kabete, Kenya, during the 2014 to 2015 rainy seasons to determin...


Nyawade, S.Karanja, N.Gachene, C.K.K.Parker, M.Schulte-Geldermann, Elmar[Susceptibility of soil organic matter fractions to soil erosion under potato-legume intercropping systems in central Kenya]Susceptibility of soil organic matter fractions to soil erosion under potato-legume intercropping systems in central Kenya

Integrating crop species with different photosynthetic pathways has great potential to increase efficiency in the use of scarce resources. In order to tap the resource complementarity emanating from this mix, this study intercropped potato (Solanum tuberosum L.) with lima bean (Phaseolus lunatas ...


Nyawade, S.Karanja, N.Gachene, C.K.K.Gitari, H.I.Schulte-Geldermann, ElmarParker, M.[Intercropping optimizes soil temperature and increases crop water productivity and radiation use efficiency of rainfed potato.]Intercropping optimizes soil temperature and increases crop water productivity and radiation use efficiency of rainfed potato.
