    Topics: Physics
    Notes: Abstract Total cross-sections for electron impact excitation of 11 S – 23 S transition in helium have been calculated using variable-charge Coulomb-projected Born approximation and also using a distorted wave model in which the prior form of theT-matrix is used. The comparison of the two sets of results enables us to make certain observations about the suitability of the variable-charge Coulomb-projected Born approximation.

    Notes: Abstract Greenhouse experiments were conducted using potted soil (Fe-deficient Typic Ustochrept) to study the influence of the vesicular-arbuscular mycorrhizal fungi (VAM), Glomus macrocarpum and G. fasciculatum, on the mobilisation of Fe in broccoli (Brassica oleracea L. var. italica Plenck) in the presence of pyrite and farmyard manure (FYM). Individual applications of either VAM or pyrite with NPK fertiliser significantly enhanced both the Fe2+ content in leaf tissue and total uptake of Fe and resulted in increased curd and straw yields of broccoli compared to those observed with NPK alone. Though the application of FYM decreased the Fe2+ content in leaf tissue relative to plants supplied NPK alone, this result was not statistically significant. The available Fe content in soil, after harvest of broccoli, was found to be lower in the presence of VAM than in the control.

    Notes: Abstract Nodule number, dry weight of shoot and root biomass of legumes (Leucaena leucocephala, Glycine max, Cajanus cajan, Phaseolus mungo, Phaseolus aureus, Vigna unguiculata) were enhanced by inoculation with live yeast cells (Saccharomyces cerevisiae). Root infection (native VAM) and the formation of vesicles, arbuscules and spores were also increased with yeast inoculation. The increase in the parameters varied with legume and the type of yeast culture. Perceptable differences in the effectiveness of yeast culture (live and dead), were also observed.

    Associative effect ofAzospirilium brasilense withRhizobium japonicum on nodulation and yield of soybean (Glycine max) (1979)
    Springer
    Plant and soil 53 (1979), S. 387-392 
    Details
    ISSN: 1573-5036
    Keywords: Associative effect ; Azospirillum brasilense ; Grain yield ; Nodulation ; Rhizobium japonicum ; Soybean

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Azospirillum was associated with nodules of soybean. In general, seed inoculation with a broth culture ofAzospirillum brasilense alone significantly increased nodulation and grain yield of soybean grown in pots in unsterilized soil with different levels of urea ranging from 0 to 80 kg N/ha. This trend was significantly reproducible in a second experiment when a carrier based inoculant of the bacterium was used for seed inoculation. Inoculation withRhizobium japonicum andA. brasilense in combination generally increased grain yield in both the experiments, although the data were not significant.

    Root nodulation studies inAeschynomene aspera (1980)
    Springer
    Plant and soil 56 (1980), S. 491-494 
    Details
    ISSN: 1573-5036
    Keywords: Aeschynomene ; Azospirillum ; Rhizobium ; Stem nodules
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Fifteen isolates of nodule bacteria were isolated from root and stem nodules ofAeschynomene aspera and they were characterized as Rhizobium by well known laboratory tests. All these isolates together with other efficient strains of known rhizobia belonging to different cross-inoculation groups were evaluated for their nodulation abilities onAeschynomene aspera, Cajanus cajan (pigeon pea),Cicer arietinum (chickpea),Pisum sativum (pea),Trifolium repens (clover),Medicago sativa (lucerne),Lens culinaris (lentil),Glycine max (soybean),Vigna sinensis (cowpea),Vigna radiata (mung bean),Vigna mungo (urd bean) andArachis hypogea (peanut). The results demonstrated that Rhizobium fromAeschynomene could form nodules only on its homologous host (Aeschynomene) but not on other legumes tested. Secondly, none of the rhizobia of other cross-inoculation groups could nodulateA. aspera.

    ISSN: 1573-5036
    Keywords: Cicer arietinum ; Glomus fasciculatum ; Rhizobium
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Seed inoculation with Rhizobium and soil inoculation withGlomus fasciculatum increased nodulation, nitrogen and phosphorus concentration in plants and yield of chickpea (Cicer arietinum) var. BG 212 in pots containing unsterilized soil especially with 50kgP2O5 ha−1 in the form of superphosphate. Inoculation with Rhizobium orG. fasciculatum separately or in combination significantly increased the N2 fixed in straw and grain than uninoculated controls as determined by15N atom percent excess of plants grown in soil amended with labelled ammonium sulphate (15NH4)2SO4) at the rate of 20kg N ha−1. These increases were most pronounced when P was applied at 50kgP2O5 ha−1.

    Root hair infection and nodulation in lucerne (Medicago sativa L.) as influenced by salinity and alkalinity (1974)
    Springer
    Plant and soil 40 (1974), S. 261-268 
    Details
    ISSN: 1573-5036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Experiments with lucerne (Medicago sativa L.) under bacteriologically controlled conditions on the effects of chloride, carbonate and bicarbonate of sodium, alkaline pH levels and saline/alkaline soil extracts demonstrated that increasing levels of salinity/alkalinity of the root medium resulted in a root system devoid of root hairs, mucilaginous layer and infection thread formation in spite of the optimum growth of Rhizobium under such conditions. The results point out the existence of ‘alkali sensitive steps’ in the early phases of nodulation which lead to an elimination of legume ‘rhizosphere’ as postulated by earlier workers.

    Nodulation and serological studies of Rhizobia from six species of Arachis (1974)
    Springer
    Plant and soil 40 (1974), S. 535-544 
    Details
    ISSN: 1573-5036
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Rhizobium strains isolated from root nodules of Arachis hypogea (cultivated species), A. duranensis, A. prostrata, A. villosa, A. glaberata and A. marginata (wild species) were tested for nodulation on a cultivated variety of A. hypogea and studied for serological properties by tube agglutination and immuno-diffusion techniques. Rhizobia from wild species nodulated the cultivated variety but the morphology and the pattern of nodulation differed. Based on the nitrogen content of shoots and nodules, it was observed that some isolates from A. duranensis were most effective on A. hypogea whereas all the isolates from the other wild species of Arachis were least effective. No cross reaction was observed between isolates from A. hypogea and antisera of isolates from A. marginata and A. glaberata. Similarly, antisera of isolates from A. hypogea did not react with antigens of A. glaberata and A. marginata strains. On the other hand, antisera of isolates from A. villosa and A. prostrata showed wide spectrum of cross reactivity. All the cross-agglutinating strains (titer value 1/200 or above-formed diffusible precipitin bands in agar. Higher agglutination titer values were attributed to slow diffusible strain specific antigens. The cross-reacting strains which showed common fast diffusible antigen bands (identical or partially identical) with a particular antiserum, always showed partial clearing of the agglutination suspension even at 1/100 dilution of the antiserum. re]19730608

    Notes: Abstract A field observation that roots of sandal wood tree (Santalum album (L.)) formed direct haustorial connections with root nodules of nodulating legumes was confirmed by pot culture studies on interaction between sandal wood plants and pigeonpea (Cajanus cajan (L.) Millsp.) or Pongamia glabra Vent. plants. The number of nodules and nitrogen content of plants decreased in parasitized nodulating species with corresponding increase in the nitrogen content of sandal plants. The root region of sandal had more of nitrogen-fixing bacteria and VAM fungi than those of pigeonpea.

    Notes: Summary Growth and phosphorus uptake of pearl millet (Pennisetum americanum) on an unsterile, phosphorus-deficient soil was improved by the seed inoculation withAzospirillum brasilense or soil inoculation with the vesicular-arbuscular mycorrhizal fungi (Acaulospora,Gigaspora margarita, Glomus fasciculatum). These microorganisms acted synergistically when added simultaneously and the response was significant withAzospirillum brasilense + Gigaspora margarita andAzospirillum brasilense + Glomus fasciculatum combinations over uninoculated control as far as the dry matter content of shoots, root biomass and phosphorus uptake of the millet was concerned.
