Abstract:
The influence of soil amendment with four plant species including Lantana camara, Mirabilis jalapa, Catharanthus roseus and 0scirnurn basilicum, and a conventional nematicide carbofuran was tested on population dynamics of three plant parasitic nematode species such as Xiphinema americanum, Merlinius sp. and Helicotylenchus indicus in the rhizospheres of date-palm at Kararo, District Khuzdar, Balochistan. A field experiment was established during August 2003-August 2004 in a randomized complete block design and soil was sampled at 0, 3, 6, 9 and 12 month intervals after amendment. Treatment with chopped leaves of plant species differentially influenced nematode population densities. Likewise, treatments influenced nematode populations differently at different sampling period. Carbofuran was found to be the most effective treatment in reducing populations of all the nematode species. When plant species were compared for nematicidal potential, populations of X. americanum was reduced most following soil amendment with 0. basilicum while those of Merlinius sp. and H. indicus by L. catnara. Regardless of the treatment, rhizospheres of date-palm harboured highest populations of X. americanum followed by H. indicus and Merlinius sp. Soil amendment with L. camara also significantly enhanced yield of date followed by O. basilicum.
