Journal Article 2003-12

Rice mill waste as organic manure on a degraded Alfisol

Autor: Schulz, S. Tian, G. Oyewole, B. Bako, S.

In much of sub-Saharan Africa (SSA), the lack of organic soil amendments constitutes one of the principal causes for declining soil fertility in intensifying farming systems. The challenge, therefore, remains to increase the availability of organic inputs and to develop recommendations for their ...

An index for assessing the quality of plant residues and evaluating their effects on soil and crop in the (sub) humid tropics

Autor: Tian, G. Brussaard, Lijbert Kang, B.

An equation was developed for calculating a plant residue quality index (PRQI) in the (sub-)humid tropics using the C/N ratio and lignin and polyphenol concentration of plant residues. Among 18 plant species tested, there was a large variation in PRQI. The PRQI was correlated with the decompositi...

Evaluation of phytotoxic effects of Gliricidia sepium (Jacq.) Walp prunings on maize and cowpea seedlings

Autor: Tian, G. Kang, B.

Phytotoxic effects ofGliricidia prunings were tested on maize seedlings in the laboratory and on maize and cowpea seedlings in the field. In the laboratory test, growth of maize seedlings was significantly depressed by addition of leachate ofGliricidia prunings. In the field, leaf, chlorosis of m...

Longterm alley cropping with four hedgerow species on an Alfisol in southwestern Nigeria effect on crop performance, soil chemical properties and nematode population

Autor: Kang, B.T. Caveness, F.E. Tian, G. Kolawole, G.O.

A longterm alley cropping trial was undertaken on an eroded Oxic paleustalf in the forest-savanna transition zone of southwestern Nigeria from 1981–1993. Two nitrogen fixing hedgerow species (Gliricidia sepium and Leucaena leucocephala) and two non legume hedgerow species (Alchornea cordifolia an...

Soil microarthropod populations under natural and planted fallows in southwestern Nigeria

Autor: Adejuyigbe, C.O. Tian, G. Adeoye, G.O.

Microarthropods, such as soil mites (Acari) and springtails (Collembola), with body width between 0.08 mm and 0.5 mm play important roles in soil fertility maintenance through their regulatory activities in decomposition and nutrient turnover. Observations were made at IITA, Ibadan, southwestern ...

Nitrogen, Ca and Mg release from leaves of ten selected plant residues with varying chemical compositions was studied under laboratory conditions. Three patterns of N-release were observed over a seven week incubation period: (a)Gliricidia sepium, Leucaena leucocephala, Mucuna pruriens andCentros...
