Research ArticleOpen accessIn the abstractCorn Response to Nitrogen Timing and Rate under Strip Tillage and Low-Yield Environment in Southeastern Coastal PlainsPawel Wiatrak, Ahmad Khalilian, Guihua ChenProblem statement: Insufficient rainfall under low yield environment may affect nitrogen management, plant growth indices and grain yields of corn (Zea mays L.). Approach: The objective of this study was to determine the effects of two N application timings (all at planting and as split application with N applied at planting and V6 stage) and five N fertilizer rates (0, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 10 Mar 2011 · 7,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractGlomalin Production and Microbial Activity in Soils Impacted by Gypsum Mining in a Brazilian Semiarid AreaAdalia Cavalcanti do Espírito Santo Mergulhao, Helio Almeida Burity, Fabio Sérgio Barbosa da Silva et al.Problem statement: Mining activities involve the removal of the vegetal cover and the soil organic layer, causing a severe environmental impact. In Northeast Brazil, 40% of the world’s crude gypsum is found in a semiarid area, making this region responsible for 95% of the gypsum demand in the national market. Although economically important, this activity is harmful to the environment. … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 4 · 11 Nov 2010 · 9,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractElapse Time Factor on Induced Vegetative Moisture Uptake in an Unsaturated SoilMuazu Mohammed Abdullahi, Nazri Bn Ali, Kamarudin Bn Haj AhmedProblem statement: Soil consolidation is generally time dependent, therefore soil displacement as a result root water uptake is space and time dependent. The time-dependent nature of abstraction of ground water by vegetation need to be evaluated in order understand the effect of time elapse on matric suction a generation and subsequent ground displacement. Approach: The current approach used the theory … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 7,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractDaily distribution Map of Ozone (O3) from AIRS over Southeast AsiaJasim M. Rajab, M.Z. MatJafri, H.S. Lim, K. AbdullahProblem statement: Daily retrieved Ozone (O3) column data for 12 day for periods varying (11-18 August) 2005 and 2003 and (12-19 February) 2005, obtained from the Atmospheric Infrared Sounder AIRS, are utilized to investigate the ozone distribution over the Southeast Asia. Approach: AIRS included on the Earth Observing System (EOS) Aqua satellite launched on 4 May 2002. Ozone (O3) is … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of N and K Fertilizers on Nutrient Leaching and Groundwater Quality under Mature Oil Palm in Sabah during the Monsoon PeriodPetronella G. Ah Tung, Mohd Kamil Yusoff, Nik Muhamad Majid et al.Problem statement: The oil palms are mainly grown in the humid tropics with high rainfall. Soluble Nitrogen (N) and Potassium (K) fertilizers are commonly required by the oil palm plantations to maximize palm productivity due to the highly weathered soils with low fertility. Thus, leaching losses of N and K nutrients may be unavoidable and these nutrients may move further … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 10,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Adaptive Measures Among Smallholder Farmers in Akwa Ibom State, NigeriaObot Akaninyene, Obiekwe NgoziAgricultural production/activities in Nigeria depends on rainfall, which often occurs only at certain times of the year and thus makes agriculture very susceptible to crop failure, insect infestation which causes poor returns on agricultural produce for farmers . Adoption of climate change mitigating strategies is key to coping with variations in weather conditions and the achievement of increased agricultural production … …American Journal of Agricultural and Biological Sciences, Vol. 17, Issue 1 · 19 Sep 2022 · 6,266 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdafruit IO Based Smart Irrigation System using MQTT Protocol for Urban FarmingDevesh Mishra, Prakhar Yadav, Vandana Yadav et al.Freshwater is needed for irrigation and nutrient supply to plants to make up for the lack of rainfall. Agricultural activities consume more than 70% of the available freshwater. This emphasizes the importance of responsible management of water for irrigation using smart Internet of Things (IoT) based agricultural practices combined with irrigation-related technologies The purpose of this research article is to … …Journal of Computer Science, Vol. 18, Issue 5 · 23 May 2022 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtended Fuzzy Decision Support Model for Cropland Recommendation of Food Cropping in IndonesiaLucky Christopher Chen, Nurcahyo Wibowo, Ditdit Nugeraha UtamaFood crops are the preferred crops to be cultivated on agricultural land in Indonesia, which has a wide area available for use as agricultural land. Each region’s agricultural lands in Indonesia have distinct features (e.g., water capacity, land porosity, land height, etc.). Rice, maize, red beans and green beans are significant food crops that are commonly cultivated in Indonesia. The … …Journal of Computer Science, Vol. 17, Issue 8 · 8 Sep 2021 · 6,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Nonlinear Models for Dry Matter Yield of Brachiaria Hybrid cv Cayman in Drought Season by BootstrappingDanny Villegas Rivas, Nora Valbuena Torres, Manuel Milla Pino et al.The dynamics of biomass accumulation at different seasons of the year is of vital importance in the production of a forage species. In this study nonlinear models (logistic and gompertz) to describe growth dynamics of plants based on dry matter yield of Brachiaria hybrid Cayman at different interval between cuts in drought season were used. Results for logistic and gompertz … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 15 Mar 2021 · 6,643 accessesView PDFCite
