Research ArticleOpen accessPhrase in the titleDetermination of Draft Force for a 3-bottom Disc Plough Under Sandy Loam Soil ConditionsPaul Okoko, Emmanuel A. AjavThis study was performed to determine the draft force for a 3-bottom disc plough under sandy loam soil conditions. The experiments were conducted using five different tractor speeds (3.6, 5.4, 7.2, 9.0 and 10.8 kilometer per hour(km)) and three tillage depths (10, 20 and 30 centimeter(cm)) with a view to determine the actual implement speed at the different tillage depths. … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 15 May 2020 · 7,390 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSimplified Procedure for Unsaturated Flow ParametersNatthawit Jitrapinate, Vichai Sriboonlue, Kriengsak Srisuk, Dolrerdee HormdeeProblem statement: The unsaturated hydraulic conductivity K(θ) and Soil Water Characteristic Curve (SWCC) for saline soil or soil directly contacted with saline water are not permitted using several apparatus to determining. Approach: A simplified method to determine K(θ) and SWCC by using simple apparatus is presented. Using the proposed numerical model with the van Genuchten equations and inverse calculation for … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,832 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Technology for Agriculture at Extreme Altitudes: Design and Evaluation of a Sprinkler Irrigation System in a Peruvian High Andean CommunityJuan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Daniel Olivier Carranza Lizana et al.In high-altitude agroecosystems, erratic rainfall patterns and steep topography severely constrain crop productivity by exposing plants to soil water deficits during critical phenological stages. This study aimed to enhance the productivity of eleven staple and horticultural crops corn (Zea mays), tomato (Solanum lycopersicum), cucumber (Cucumis sativus), eggplant (Solanum melongena), lettuce (Lactuca sativa), carrot (Daucus carota), barley (Hordeum vulgare), celery (Apium … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 2 Oct 2026 · 663 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Arduino-Based Robotic Arm Yam Heap MakerAgbese Raphael, Dagwa Ishaya Musa, Nurudeen Abdulhakeem Hassan, Adekunle JoshuaIn this study, a prototyperobotic arm yam heap-maker using Arduino was developed. Nigeria produces around75% of global yam production which is widely consumed as staple foods in Africaand Asia and as raw materials for processing into other finished goods. Theproduction of this economic commodity is largely crude and labor-intensive assuch the need to adopt a modern approach to farming. The … …Journal of Mechatronics and Robotics, Vol. 6, Issue 1 · 2 Sep 2022 · 6,468 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Organic Carbon Stock under Different Age Ranges of Cashew Agroecosystems in the Sudano-Sahelian Zone of CameroonAwé Djongmo Victor, Noiha Noumi Valery, Zapfack LouisThe aim of this study was to quantify the current soil organic carbon stock under different age ranges of cashew agroecosystems in the Sudano-Sahelian zone of Cameroon in the context of greenhouse gas emissions and land degradation. It is so crucial for combating climate change and improving ecological restoration. Random field sampling was carried out on 0-10, 10-20 and 20-30 … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 28 Dec 2020 · 6,995 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect 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 · 7,748 accessesView PDFCite

Research ArticleOpen accessIn the abstractDevelopment and Evaluation of Tractors and Tillage Implements Instrumentation SystemS. A. Al-Suhaibani, A. A. Al-Janobi, Y. N. Al-MajhadiProblem statement: Field machines contribute a major portion of the total cost of crop production. Proper selection and matching of farm machinery is essential in order to reduce the cost of crop production. Performance data for tractors and implements are, therefore, essential for farm machinery operators and manufacturers alike. The aim of this study was to develop and evaluate an … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,313 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mixing Urea with Humic Acid and Acid Sulphate Soil on Ammonia Loss, Exchangeable Ammonium and Available NitrateMohd Taufik Mohd Yusuff, Osumanu Haruna Ahmed, Nik Muhamad Ab MajidProblem statement: Ammonia loss due to rapid hydrolysis of urea in soil following surface application can be substantial. Ammonia loss in agriculture is estimated to be 1 to 60%. This laboratory study compared the effect of three different urea-humic acid-acid sulphate soil mixtures on NH3 loss and soil ammonium and nitrate contents, with loss from surface applied urea without additives … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 8,911 accessesView PDFCite
