(College of Agriculture and Veterinary Sciences, University of Nairobi, 2010) -
Nirogen Replenishment In The East African Highlands Through Biological Nitrogen Fixation And Legume Inoculation.
(University of NairobiDepartment of Land Resource Management and Agricultural Technology, 1998) -
Nitrogen and phosphorous uptake by potato (Solanum tuberosum L.) and their use efficiency under potato-legume intercropping systems
(University of Nairobi, 2018)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 ... -
Nitrogen Fixation by Natural Populations of Acacia Senegal in the Drylands of Kenya Using 15N Natural Abundance
(University of Nairobi,College of Agriculture and Veterinary Sciences,, 2013)Nitrogen (N) fixation was estimated for three Acacia senegal (L.) (A. senegal) Willd. varieties (A. senegal var. senegal, kerensis, and leiorhachis) growing naturally in different sites in the dryland areas of Kenya. The ... -
Nitrogen fixation in tropical agriculture and forestry
(Department of Land Resource Management and Agricultural Technology, 1987)Nitrogen compounds comprise from 40 to 50 percent of the dry matter of protoplasm, the living substance of plant cells. For this reason, nitrogen is required in large quantities by growing plants and is indeed the key to ... -
Nitrogen fixation potential and residual effects of selected grain legumes in a Kenyan soil
(Department of Plant Science and Crop Protection, University of Nairobi, 2013)Based on their performance attributes, butter bean (variety Ex-kasuku) and grass pea (Selection 1325) have been identified as potential alternative legumes for the maize-based cropping system in the cold semi-arid region ... -
Nitrogen level and cultivar effects on nodulation, dinitrogen fixation and yield of grain legumes: I. Cowpea cultivars
(Department of Land Resource Management and Agricultural Technology, 1985)N fixation was studied by the 15N method in Vigna unguiculata cv. ERI-2, Vita 4 and Machakos 74 grown in a field which had been fallow for 3 years and given 20 or 100 kg N/ha. The higher N rate reduced nodulation in all ... -
Nitrogen level and cultivar effects on nodulation, dinitrogen fixation and yield of grain legumes: II. Common bean cultivars.
(Department of Land Resource Management and Agricultural Technology, 1985)N fixation was studied by the 15N method in Phaseolus vulgaris cv. Rose Coco, Canadian Wonder and Mwezi Moja grown in the field and given 0, 20 or 100 kg N/ha. Nodulation, DM yield and seed yield did not differ significantly ... -
Nitrogen Mineralization potential (( No), mineralization rate constant (K) and time taken for half of the mineralizable nitrogen to be mineralized in four Kenya soi
(University of NairobiDepartment Of Land Resource Management And Agricultural Technology, 1998) -
Nitrogen Mineralization Potential (No) in Three Kenyan Soils, Nitisols, Ferralsols and Luvisols
(University of Nairobi, 2018)Nitrogen mineralization potential is important so as to prevent over-fertilization that could lead to groundwater contamination or under-fertilization that could lead to poor nutrient provision by crops leading to low ... -

No Apparent Reduction in Schistosome Burden or Genetic Diversity Following Four Years of School-Based Mass Drug Administration in Mwea, Central Kenya, a Heavy Transmission Area
(2014)Schistosomiasis is a debilitating neglected tropical disease that infects over 200 million people worldwide. To combat this disease, in 2012, the World Health Organization announced a goal of reducing and eliminating ... -
No effect of dieldrin on progesterone production in gilts
(Department of Veterinary Pathology, Microbiology & Parasitology, 1993-08)The effect of feeding pigs with dieldrin containing feed on the progesterone profile of the estrous cycle was investigated. Eight gilts comprising three controls and five treatment animals were given feed containing 40 ppm ... -
No rain but bumper harvest: the magic of pigeonpea in semi-arid Kenya
(University of Nairobi, 2018)Land degradation and low rainfall seriously constrain agricultural production in arid and semi-arid areas. A study was conducted at Katumani Research Centre between 2009 and 2013 to investigate the effect of pigeonpea and ... -

(University of Nairobi, 2005)Today on this International Women's Day, we spend the hour with Wangari Maathai, the first African woman and first environmentalist to receive the Nobel Peace Prize. Her life story is a remarkable one. Wangari Maathai ... -
Nociception in Crocodiles : Capsaicin Instillation, Formalin and Hot Plate Tests : COMMUNICATION : Physiology
(Department of Animal Physiology, University of NairobiDepartment of Physiology, University of Bergen, 1990)Three tests of nociception were adapted for the use in crocodiles (47.0-65.2cm long). In the capsaicin instillation test, capsaicin in concentrations of 10^<-9> to 10^<-3> g/ml instilled in the eye induced concentration ... -
