Buffer pH methods for estimation of lime requirement of tropical acid soils.
(Univeristy of Nairobi, 1981)
Lime requirements (LR) of 26 acid agricultural soils were estimated using the following buffer methods: Shoemaker-McLean-Pratt single buffer (SMP-SB), SMP double buffer (SMP-DB), Mehlich buffer method for crops with high ...
The Effect of Phosphorus on Nodulation, Growth and Dinitrogen Fixation by Beans
(1983)
The effect of phosphorus on nodulation, dry matter yield and dinitrogen fixation (as determined by the 15N technique) of bean plants (Phaseolus vulgaris) was evaluated in a field experiment at three growth stages. Application ...
Nitrogen level and cultivar effects on nodulation, dinitrogen fixation and yield of grain legumes: II. Common bean cultivars.
(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 ...
The effect of level of CaCO3, inoculation and lime pelleting on the nodulation and growth of beans in five acid soils.
(Univeristy of Nairobi, 1981)
In greenhouse trials with Phaseolus vulgaris cv. Canadian Wonder grown on 5 acid soils of pH 3.9-5.1, nodule wt. decreased with increasing percentage soil C, and at 5.60% C no nodules were observed. In soils with low OM ...
Rhizobium phaseoli inoculation trials on farmers' fields in Kenya.
(Univeristy of Nairobi, 1988)
A study was conducted on farmers' fields in Kikuyu Division, Kenya, to determine whether inoculating bean seeds with Rhizobium phaseoli could match the N supplied by 200 kg of diammonium phosphate (DAP) for pure stands of ...
Soil acidity components of tropical acid soils: their roles in determining lime requirement values and the effect of lime upon them.
(Univeristy of Nairobi, 1982)
Clay content, pH, organic matter content (%C), cation exchange capacity (CEC), exchangeable Al, exchangeable Mn, exchangeable acidity (ACe), residual acidity (ACr) and total acidity of 26 agricultural soils were determined. ...
