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 ... -

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 ... -
