Controlling soil erosion in smallholder potato farming systems using legume intercrops
Nyawade, Shadrack O.; Gachene, Charles K.K.; Karanja, Nancy N.; Gitari, Harun I.; Schulte-Geldermann, Elmar; Parker, Monica L. (University of Nairobi, 2019)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 ... -
Decomposition Rates of Biomass Obtained from Six Month-Old Tephrosia vogelii, Tithonia diversifolia and Natural Fallow Vegetation at Maseno, Kenya
Rutunga, Venant; Karanja, Nancy K.; Gachene, Charles K.K. (Department of soil science, 2001)Organic residues incorporated into soil release their nutrients through decomposition. This process may be slow or rapid depending on the biomass quality and environmental conditions. For a period of 8 months, an incubation ... -
Optimizing yield and economic returns of rain-fed potato ( Solanum tuberosum L.) through water conservation under potato-legume intercropping systems
Gitari, Harun I.; Gachene, Charles K.K.; Karanja, Nancy N.; Kamau, Solomon; Nyawade, Shadrack; Kalpana, Sharma; Schulte-Geldermannb, Elmar (University of Nairobi, 2018)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 ... -
Short-term dynamics of soil organic matter fractions and microbial activity in smallholder potato-legume intercropping systems
Nyawade, Shadrack O.; Karanja, Nancy N.; Gachene, Charles K.K.; Gitari, Harun I.; Schulte-Geldermann, Elmar; Parker, Monica L. (University of Nairobi, 2019)Continuous cultivation of potato (Solanum tuberosum L.) in monoculture systems represents the greatest factor deteriorating soil organic matter (SOM) in smallholder farms. With an aim to breaking this norm, a 2-year field ...
