Research ArticleOpen accessIn the abstractTransforming Spatio-Temporal Yield Maps to Classified Management Zone Maps for Efficient Management of Oil PalmAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedOne of the major challenges in oil palm plantations today is proper interpretation of yield maps for site-specific management and development of classified management zone maps for its efficient management. A study was conducted on an on-going fertilizer response trial in Sabah, Malaysia to examine the possibility of converting spatio-temporal yield maps of oil palm to classified management zone maps … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,500 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpatial-Temporal Yield Trend of Oil Palm as Influenced by Nitrogen Fertilizer ManagementAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedOne of the major challenges in oil palm (Elaeis guineensis Jacq.) plantations today is proper interpretation of yield maps for site-specific management and identification and understanding of the causal factors influencing the variability of oil palm yields. A study was conducted to examine the structural yield variation in order to assess the spatial and temporal yield trends so as to … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,549 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRelationships between Heavy Metal Concentrations in the American Oyster (Crassostrea virginica) and Metal Levels in the Water Column and Sediment in Apalachicola Bay, FloridaDennis A. Apeti, Larry Robinson, Elijah JohnsonThis study aims to assess baseline concentrations of heavy metals (Cd, Cr, Cu, Pb and Zn) in the oyster soft tissue as they relate to concentrations in the water column (particulate phase) and sediment in Apalachicola Bay. In order to conduct these assessments, a total of 360 samples, collected in two seasons (winter and summer) and were analyzed using atomic … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,344 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordStudy on the Distribution of Endomycorrhizal Fungi in Some Species Root-Plants in BaliMeitini Wahyuni Proborini, Deny Suhernawan YusupPlants growing on poor soils are commonly associated with endomycorrhizal fungi as a mutualism symbiotic. The fungus takes a role on enhancement of the uptake of soil mineral nutrients particularly phosphorus, thereby enhancing host plant vigor. Despite some of Bali areas particularly in Karangasem and Buleleng have poor soil condition, less study on the endomycorrizhal fungi have been undertaken. The … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 20 Dec 2017 · 7,492 accessesView PDF Cite
