Research ArticleOpen accessIn the keywordsEffect of Organic Based N Fertilizer on Dry Matter (Zea mays L.), Ammonium and Nitrate Recovery in an Acid Soil of Sarawak, MalaysiaSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid et al.Problem statement: Exchangeable ammonium (NH4+) could be recovered by humic and fulvic acids from humic substances. The ability of these acids in fixing or retaining NH4+ has been demonstrated in many findings and reports. Both acids could affect the plant growth, nutrients uptake by enhancing photosynthesis rate and root growth among others. Thus, in this study, the effect of both … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 8,244 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTransforming 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 PDFCite
Research ArticleOpen accessIn the abstractEffects of Maize Potato Intercropping and Different Fertilization Methods on Rhizosphere Soil Microorganisms and Yield of PotatoHuanjin Ma, Shengguang Xu et al.A field experiment with three replicates was conducted to explore the effects of maize-potato intercropping and different nitrogen application strategies on rhizosphere soil microorganisms and potato yield. Microbial community analysis was based on relative abundance. Maize-potato intercropping improves land use efficiency, yet how differentiated nitrogen management regulates rhizosphere microecology and potato productivity in this system remains unclear. Clarifying nitrogen-mediated shifts … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 14 Sep 2026 · 790 accessesView PDFCite
