Abstracts |
Five fodder crops, Zea mays, Medicago sativa, Trifolium alexandrinum, Avena sativa, and Sorghum vulgare were inoculated with a consortia of indigenous arbuscular mycorrhizal (AM) fungi in non-sterile PO43--deficient sandy loam soil amended with organic matter under field conditions. Shoot and root dry weights and total uptake of P and N of all the test plants were significantly increased by AM inoculation. Mycorrhizal inoculation increased yield in terms of shoot dry weight by 257% in T. Alexandrinum followed by 50% in A. Sativa, 28% in Z mays, 20% in M. Sativa and 6% in S. Vulgare. Variation in dependence on mycorrhiza was observed among the fodder crops. T. Alexandrinum showed a maximum dependence of 72% in contrast to 5.7% dependency in S. Vulgare. Plant species showed differences in percentage AM colonization, with a high root infection recorded in Z mays (76%). Spore production and infectious propagules (IP) were as high as 78 spores/IP g(-1) and 103 spores/IP g(-1) in S. Vulgare. This study clearly indicates the potential of using indigenous AM inoculations in fodder crops grown in marginal soils along with in situ large-scale production of AM inocula. |
