    Factors determining the occurrence of the agroforestry system withAcacia mearnsii in Central Java (1988)
    Springer
    Agroforestry systems 6 (1988), S. 119-135 
    Details
    ISSN: 1572-9680
    Keywords: Agroforestry ; Acacia mearnsii ; Central Java ; commercialization ; farming system development

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract In 1922, the colonial government introducedAcacia mearnsii in the tobacco-growing region of Wonosobo. Soon this species was accepted by the local people who developed an agroforestry system based on a rotation ofA. mearnsii and agricultural crops. Now, the growing of the black wattle is becoming less popular. To study the prospects for this agroforestry system 143 farmers from 5 villages were interviewed. The functions of this agroforestry system are the production of fuelwood and bark (which contains tannin for the leather industry), soil conservation and soil improvement. The following factors affectA. mearnsii growing: population density (which affects farm size and demand for domestic fuelwood), tobacco-processing (which requires fuel), topography and commercialization. If current trends continue, the contribution of the functions of this agroforestry system to welfare will not be sufficient to compete successfully with subsistence and cash crops like potatoes and tobacco. Therefore,A. mearnsii cultivation is expected to decline further.

    Soil acidity in relation to groundnut-Bradyrhizobium symbiotic performance (1994)
    Springer
    Plant and soil 163 (1994), S. 165-175 
    Details
    ISSN: 1573-5036
    Keywords: Arachis hypogaea ; Bradyrhizobium ; groundnut ; soil acidification ; soil acidity

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Effects of soil acidity on groundnut-Bradyrhizobium symbiotic performance were studied in a potted, sandy soil in a glasshouse in Zimbabwe. The soil was limed to soil-pH levels of 5.0 and 6.5. Soil acidity negatively affected plant development, measured as leaf area and plant dry weight, while nodulation was enhanced. This acidity-enhanced nodulation was most evident when nodulation was caused by the indigenousBradyrhizobium population. Effects of soil acidity differed between groundnut cultivars andBradyrhizobium spp. strains, the former having greater importance. TwoArachis hypogaea L. Spanish-type cultivars, Falcon and Plover, performed equally well at neutral soil pH, but Falcon was more acid tolerant. Comparison of the symbiotic performance in neutral versus acid soil of twoBradyrhizobium spp. strains, MAR 411 (3G4b20) and MAR 1510 (CB 756), showed that MAR 411 performed superiorly in neutral soil, but MAR 1510 in acid soil. The indigenousBradyrhizobium population was more effective than was inoculation with strains MAR 411 or MAR 1510. Comparison of twelveBradyrhizobium spp. strains for their symbiotic performance in acid soil showed that some strains were totally ineffective under acidity stress (MAR 253, MAR 967 and MAR 1506), while others performed well.Bradyrhizobium spp. strain MAR 1576 (32 H1) ranked highest for nitrogen accumulation, plant dry weight and leaf area, with strains MAR 1555 (TAL 11) and MAR 1510 following closely. Nitrate fertilisation of groundnut plants led to soil alkalinisation, while nitrogen fixation resulted in soil acidification. Soil acidity in combination with soil sterilisation gave rise to symptoms associated with Al and Mn toxicity.
