Assessment of groundwater quality in Vihiga County, Kenya
Kanda, Edwin Kimutai; Avulala, Minyade K.; Olendo, Emmy; Mukolwe, Micah M.; Awandu, Willis; Lutta, Valery O.; Ong'or (T), Basil; Khaemba, Alex W. (Progress in Sustainable Development, 2023-03-17)Vihiga County does not have a sewerage system and therefore people rely on onsite sanitation system. Poorly designed and located on-site sanitation systems are potential threats to groundwater which is the main source of ... -
Calibration and validation of the AquaCrop model for full and deficit irrigated cowpea (Vigna unguiculata (L.) Walp)
Kanda, Edwin Kimutai; Senzanje, Aidan; Mabhaudhi, Tafadzwanashe (Science Direct, 2020-10-16)The study aimed at calibrating and validating the AquaCrop model for cowpea under full and deficit irrigation. The experiments used to calibrate and validate AquaCrop consisted of rainfed supplemented with irrigation, ... -

Kanda, Edwin Kimutai; Senzanje, Aidan; Mabhaudhi, Tafadzwanashe (Physics and Chemistry of the Earth, Parts A/B/C, 2021-11)The study aimed at calibrating and validating the AquaCrop model for cowpea under full and deficit irrigation. The experiments used to calibrate and validate AquaCrop consisted of rainfed supplemented with irrigation, ... -
DETERMINATION OF IRRIGATION WATER REQUIREMENT OF TOMATO CROP IN RACHUONYO NORTH SUB CATCHMENT OF WESTERN KENYA USING CROPWAT MODEL
Odhiambo, Kevin O.; Ong'or, Basil; Kanda, Edwin Kimutai (East African Agricultural and Forestry Journal, 2022-08-26)Irrigation water management is necessary for a successful irrigation system. Knowledge and tools on irrigation management is thus a requisite for profitable and sustainable use of the scarce water resources in Kenya. The ... -
Effect of Moistube and subsurface drip irrigation on cowpea (Vigna unguiculata (I.) Walp) production in South Africa
Kanda, Edwin Kimutai; Senzanje, Aidan; Mabhaudhi, Tafadzwanashe (Water SA, 2020-04-29)Moistube Irrigation (MTI) is a new subsurface irrigation technology where the water emits from a semi-permeable membrane at a slow rate depending on applied pressure and soil water potential. There is lack of information ... -
Effects of oil exploration on surface water quality- a review
Lusweti, Elizabeth; Kanda, Edwin Kimutai; Obando, Joy; Makokha, Mary (Water Practice & Technolog, 2022-08-27)The oil industry is a source of revenue and foreign exchange for an economy. Nevertheless, oil exploration is an inherent risk to the environment due to the pollution of water resources, especially surface water resources. ... -
Hydraulic and clogging characteristics of Moistube irrigation as influenced by water quality
Kanda, Edwin Kimutai; Mabhaudhi, Tafadzwanashe; Senzanje, Aidan (Journal of Water Supply: Research and Technology, 2018-06-12)Irrigation consumes approximately 70% of total freshwater use worldwide. This necessitates the use of efficient irrigation methods such as micro-irrigation. Moistube irrigation (MI) is a new subsurface irrigation technology ... -
Modelling soil water distribution under Moistube irrigation for cowpea (VIGNA unguiculata(L.) Walp.) crop(dagger)
Kanda, Edwin Kimutai; Senzanje, Aidan; Mabhaudhi, Tafadzwanashe (Irrigation and Drainage, 2020-07-22)Moistube irrigation (MTI) is a type of technology which uses a semipermeable membrane to emit water continuously in response to soil water potential and applied pressure. Soil water dynamics under MTI incorporating plant ... -
Nutritional yield and nutritional water productivity of cowpea (Vigna unguiculata L. Walp) under varying irrigation water regimes
Kanda, Edwin Kimutai; Senzanje, Aidan; Mabhaudhi, Tafadzwanashe; Mubanga, Shadrack Chisenga (Water SA, 2020-07)There is a need to mainstream traditional crops in sub-Saharan Africa, in order to tackle food and nutritional insecurity through incorporating nutritional quality into crop water productivity, in the wider context of the ... -
Soil water dynamics under Moistube irrigation
Kanda, Edwin Kimutai; Senzanje, Aidan; Mabhaudhi, Tafadzwanashe (Physics and Chemistry of the Earth, 2020-02)The design and management of irrigation systems require knowledge of soil water movement. There are few studies on soil water dynamics of Moistube irrigation (MTI) since it is a relatively new type of subsurface irrigation ... -
The status and challenges of a modern irrigation system in Kenya: A systematic review
Kanda, Edwin Kimutai; Lutta, Valery Osimbo (Irrigation and Drainage, 2022-03-14)The modernization efforts of the irrigation subsector in Kenya have been hampered by several challenges. This review describes the status and challenges facing irrigated agriculture in Kenya. The results indicated that as ... -
