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 · 7,384 accessesView PDF Cite

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 · 6,828 accessesView PDF Cite

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 · 645 accessesView PDF Cite

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 · 6,463 accessesView PDF Cite

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 · 6,993 accessesView PDF Cite

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 · 7,744 accessesView PDF Cite
