Research ArticleOpen accessEvery word in the titleSeasonal Distribution of Organic Carbon in the Surface Sediments of the Terengganu Nearshore Coastal AreaS. Hasrizal, B. Y. Kamaruzzaman, I. Sakri et al.Problem statement: The distribution of organic carbon in the surface sediment is a crucial indicator for current productivity in the ocean especially in the nearshore area. The difference of organic carbon in the surface sediment reflects the influence of current movement on the bottom sediment. Approach: This study was carried out to oversee the difference of organic carbon distribution during … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,477 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResidual Influence of Early Season Crop Fertilization and Cropping System on Growth and Yield of CassavaE. A. Makinde, O. T. AyoolaProblem Statement: In assessing fertilizer effects to sustain an intensive cropping system, the residual effects of fertilizer applied to preceding maize on the growth and yield of cassava and the effects of intercropping with soybean were studied in field experiments at Ibadan, Nigeria. Approach: Maize, established in April was fertilized using either organic manure or inorganic fertilizer or a mixture … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,971 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFinancial Assessment of a new Soil Heating Technology for Off-season Asparagus ProductionA. Luce, K. Mattas, I. Tzouramani et al.The financial effectiveness of a soil heating system placed under the crowns in each raised bed (UCR) of Asparagus plants (Asparagus officinalis L.) was evaluated and then compared with a traditional greenhouse production system (TPS), a plastic greenhouse without any heating system, in northern Greece. Several appraisal approaches, such as net present value, net present value adjusted for inflation and … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 7,868 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleSeasonal Abundance and Species Composition of Nephotettix spp., in Endemic and Non-Endemic Areas of Rice Tungro Virus Disease in South Sulawesi Province, IndonesiaAndi Nasruddin, Muhammad Danial Rahim, FatahuddinRice tungro disease is semi-persistently transmitted by five species of leafhopper. Nephotettix virescens Distant and N. nigropictus Stal. (Homoptera: Cicadellidae) are predominant species in South Sulawesi with vectoring efficiencies of 83 and 27%, respectively. Relative composition of those species affects the RTV incidence in the field. The purpose of the study was to determine the presence and abundance of those … …OnLine Journal of Biological Sciences, Vol. 16, Issue 3 · 5 Oct 2016 · 7,591 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSEASONAL DROUGHT DYNAMICS IN EL-BEHEIRA GOVERNORATE, EGYPTAmr Mossad, Hazem S. Mehawed, Ahmed El-ArabyDrought is the most damaging climate-related hazards due to the prolonged absence of precipitation. Therefore, understanding the drought dynamics is important for irrigation water management to mitigate the negative impacts on agriculture. In this study, Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) were used as effective tools for tracking the changes of water status occurred at five … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 4 Apr 2014 · 7,627 accessesView PDFCite
