Item Contour and East-West row planting systems of rubber (Hevea) for intercropping part 1. effects on growth and yield of componenet crops(Rubber Research Institute of Sri Lanka. Agalawatta, 2002) Pathirana, L.S.S.; Perera, M.K.P.Item Contour and East-West row planting systems of rubber (Hevea) for intercropping part 1. effects on growth and yield of componenet crops(Rubber Research Institute of Sri Lanka:Agalawatta, 2002) Pathirana, L.S.S.; Perera, M.K.P.Item Intercropping- a way to maximize the land productivity and to obtain economic stability(Rubber Research Institute:Agalawatte, 2004) Rodrigo, V.H.L.; Iqbal, S.M.M.; Pathirana, L.S.S.Item Rattan - a potential intercrop under rubber in Sri Lanka(Rubber Research Institute of Sri Lanka:Agalawatta, 1997) Pathirana, L.S.S.Item Shade effects on photosynthesis of cinnamon (Cinnamomum verum J. Pres)(Rubber Research Institute:Agalawatta, 1998) Pathirana, L.S.S.; Nugawela, A.; Samarasekera, R.K.Item Shade effects on photosynthesis of cinnamon (Cinnamomum verum J. Pres)(Rubber Research Institute. Agalawatta, 1998) Pathirana, L.S.S.; Nugawela, A.; Samarasekera, R.K.Item Shade effects on photosynthesis of cinnamon (Cinnamomum verum J. Pres)(Rubber Research Institute:Agalawatta, 1998) Pathirana, L.S.S.; Nugawela, A.; Samarasekera, R.K.Item Utilization of phosphorus from apatite and growth of plants inoculated with vesicular arbuscular mycorrhiza and phosphate dissolving bacteria(Rubber Research Institute:Agalawatta, 1990) Pathirana, L.S.S.; Waidyanatha, U.P.De S.; Peiris, O.S.An annual grass, Pennisetum ploystechyon (L) Schult and a perennial creeping legume Pueraria phaseoloides took up more P and grew better in an acid soil (pH 4.8) treated with a poorly soluble source of apatite. Inculation of the sterilized soil with a heterogenous mixture of a vesicular arbuscular mycorrhizal (VAM) spores extracted from the soil and with Glomus fasciculatus (E3) spores did not increase plant growth or uptake of P in soil with apatite but growth was increased considerably in soil in soil without apatite. However, inoculation with E3 type spores had no effect on growth or P uptake of Pennisetum . Phosphate dissolving bacteria (PDB) stimulated growth of Pueraria and uptake of P from a soil enriched with apatite.Item Utilization of phosphorus from apatite and growth of plants inoculated with vesicular arbuscular mycorrhiza and phosphate dissolving bacteria(Rubber Research Institute.
