Research ArticleOpen accessEvery word in the titleOptimization of Solenoid Valve for Variable Rate Application SystemSaleh Mufleh Al-Saqer, Ghulam Mubashar HassanProblem statement: The aim of this research was to optimize the performance of solenoid valve used in Variable Rate Application System (VRA) in term of time response. The overall time response is usually divided into four parts i.e., plunger opening time, pressure opening time, plunger closing time and pressure closing time. Approach: The performance and design of the a solenoid … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 8,654 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Animal Manure Application Rates on Soil Moisture Conservation at, Somali Regional State, EthiopiaTekilil WoldeThe Ethiopian economy is mainly agrarian. It employs 85% of the population and contributes 45% of the gross domestic product and 90% of the national export earnings but agriculture in Ethiopia is dominated by rainfed farming with low productivity specially dry land part of the country like Somali region. As a result, crops have severe moisture stress through their growth … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 15 Aug 2019 · 7,744 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEVALUATION OF NITROGEN APPLICATION METHODS AND RATES WITH NUTRISPHERE-N ON CORN IN SOUTHEASTERN COASTAL PLAINSPawel WiatrakApplication method of Nitrogen (N) and Nutrisphere-N may influence corn (Zea mays L.) growth and yields under dryland conditions. The objective of this study was to determine the effect of two N application methods (all at planting and split application with 35 kg N ha-1 applied at planting and remaining N at V6 stage) and five N rates (0, 45, … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 4 Jan 2014 · 7,297 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEVALUATION OF NITROGEN APPLICATION METHODS AND RATES WITH NUTRISPHERE-N ON SOIL NITRATE-NITROGEN IN SOUTHEASTERN COASTAL PLAINSPawel WiatrakNitrogen (N) application with Nutrisphere-N polymer may affect soil Nitrate-Nitrogen (NO3-N) movement in the soil. The objective was to evaluate two N application methods (all at planting and split application) and five N rates (0, 45, 90, 135 and 180 kg N ha-1) with Nutrisphere-N polymer on soil NO3-N in dryland corn (Zea mays L.) near Blackville, SC from 2010 … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 23 Dec 2013 · 7,490 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Biogas Plants by the Application of an Internal Rate of Return and Debt Service Coverage ApproachGiuseppe Bonazzi, Mattia IottiEnergy production using renewable energy has an effect on environmental sustainability and on public expenditure. In fact, this industry is heavily assisted by public support from the European Union and the Italian State. Developing and applying a method to evaluate the return on investment for companies operating in the field of renewable energy allows them to quantify their efficient use … …American Journal of Environmental Sciences, Vol. 11, Issue 1 · 6 Apr 2015 · 7,632 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE RATE FUNCTION OF S-MIXING PROCESS AND ITS APPLICATION IN EVALUATING EMPIRICAL LIKELIHOOD TESTSXing WangIn this study we show that the rate function of S-Mixing stationary process with part of the hypermixing condition is equivalent to the Kullback-Leibler distance. This finding can be used to extend the result of the optimality of empirical likelihood test in i.i.d setting to weakly depended case, so that the Asymptotic Relative Efficiency (ARE) of the empirical likelihood test … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 28 Oct 2013 · 6,615 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn-board Computer Unit Development for Precision Fertilization in Oil Palm Plantations Based on Data from a Precision Agriculture PlatformIndra Permana Solihin, Kudang Boro Seminar et al.This study aims to develop the function of the On-Board Computer Unit (OBC) device to control the Variable-Rate Fertilizer Application (VRFA) device according to the recommendations of the precision agriculture platform for oil palm (Precipalm) platform integrated into the tractor system. Then, the operational movement of tractors integrated with VRFA is to be modeled using the Dead Reckoning (DR) algorithm … …Journal of Computer Science, Vol. 20, Issue 12 · 8 Nov 2024 · 5,586 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCorn 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 · 7,992 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Hydroponic System for Purification of Anaerobically Treated Dairy Manure and Production of Wheat as a Nutritional Forage CropA. E. Ghaly, H.A. Farag, M. VermaA hydroponic system was developed and used for purification of an anaerobically treated dairy manure and production of forage crops. The effect of light duration, seeding rate and wastewater application rate on the crop yield and pollution potential reduction were studied. The results indicated that a wheat forage crop can be produced in 21 days from germination to harvest in … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,075 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanism of Garden Aquatic Plants in the Remediation of Heavy Metal-Contaminated SoilChen Chen, Guangwu LiuHeavy metals such as cadmium, lead, and mercury are resistant to microbial degradation in soil and persist for extended periods. They can bioaccumulate through the food chain, ultimately impacting human health. This study demonstrates that a combined restoration approach involving soil enhancement and garden aquatic plants, specifically through the application of ferrous sulfate, results in increased dry weight and plant … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 20 Apr 2026 · 1,497 accessesView PDFCite
