Development of a General-Purpose Test Platform for Agricultural Navigation

Research Article of American Journal of Agricultural Research Development of a General- Purpose Test Platform for Agricultural Navigation Du Juan, Wang Yanxin, An Jiahao, Jin chengqian, Yin Xiang* School of Agricultural Engineering and Food Science, Shandong University of Technology, Zibo 255000, China. Field tests are necessary in establishing navigation models and algorithms for agricultural vehicle robots. And it costs much to use tractors or combine harvesters as the platform in terms of system modification, routine maintenance and fuel consumption. The objective of this research was to develop a general-purpose test platform for conducting experiments in agricultural autonomous navigation at a low cost based on a commercially available electric vehicle. A brushless motor was utilized as the power source for automatic steering. An analog PID controller was designed to compare steering commands and actual steering angle and calculate an appropriate voltage signal as the input of the motor driver. A rotary encoder was attached to the driving wheel and a digital PID controller was implemented to determine the throttle value in real-time in maintaining the test platform at a desired speed. A CAN-bus network was established to integrate the automatic steering system and the speed control system as two nodes for information communication. And a CAN node interface was reserved for receiving commands from autonomous navigation systems to be evaluated. Field tests showed that RMS errors were 2.6 cm and 0.054 m·s-1 for lateral offset and speed control, respectively, in tracking straight paths, which indicated that the newly developed test platform met requirements for agricultural navigation experiments.

Active ingredients for weed control of food and vegetable crops in northern Côte d’Ivoire

Research Article of American Journal of Agricultural Research Active ingredients for weed control of food and vegetable crops in northern Côte d'Ivoire N. S. Singo1,2, A. Touré2, N. J. Kouakou2, Y. R. Baka2, J. Ipou IPou2 1African Center of Excellence for Climate Change, Biodiversity and Sustainable Agriculture (CEA-CCBAD), Félix Houphouët-Boigny University; 2Botany Laboratory, UFR Biosciences, Félix Houphouët-Boigny University 22 BP 582 Abidjan 22, Côte d'Ivoire Agriculture in the north of Côte d’Ivoire, like the rest of the country, is undergoing genuine development. This situation is leading producers to adopt new cultivation techniques, including the use of herbicides for weed control. Herbicides have advantages and disadvantages in their handling. Knowing how dangerous these products can be, identifying them would be advantageous, hence this study. The main objective of this study is to establish a list of herbicides used on vegetable and food crops in the study area. In the departments of Boundiali, Ferké, Korhogo, and Séguéla directed interviews were conducted with traders, producers, and firms. They focused on the active ingredients of the herbicides, the type, and the mode of use. At the end of the study, seventy-seven herbicides divided into twenty-two active ingredients were identified. Glyphosate was the most present followed by nicosulfuron. To conclude, it should be noted that herbicides are present in the habits of the producers in our study area. They still do not use the products according to the standards. These results will help improve the quality and sustainability of agriculture.

Design of Twin Screw Feather Extruder and Study of Screw Parameters

Research Article of American Journal of Agricultural Research Design of Twin Screw Feather Extruder and Study of Screw Parameters Haoze Li1, Ping Jiang1, Keying Li1, Huawei Liu1, Ping Zhang1, Guohai Zhang1* 1School of Agricultural Engineering and Food Science, Shandong University of Technology, Zibo, 255000, China. Poultry feathers are rich in amino acids and keratin resources, which is a kind of protein feed raw materials with high nutritional value. A twin-screw extruder was designed to deal with the environmental damage caused by the shortage of rapidly developing protein feed and the large amount of feather waste in China’s livestock breeding industry. The bulking machine can break the disulfide bond and hydrogen bond in feather keratin to form crude protein which can be absorbed by livestock. A kind of high-protein feed feather powder was developed while protecting the environment. The combination mode and rotation direction between two screws are discussed, the relationship between the key basic parameters of the twin screw is derived by combining the motion principle of the twin screw and the relative geometric position. It provides theoretical basis for determining screw parameters and working condition parameters in the following experimental research.

Nutritional Potential of Some Invasive Species of Macaronesia for Ruminants

Research Article of American Journal of Agricultural Research Nutritional Potential of Some Invasive Species of Macaronesia for Ruminants C.S.A.M. Maduro Dias, C.F.M. Vouzela, H.J.D. Rosa, J.S. Madruga and A.E.S. Borba University of the Azores, Faculty of Agricultural and Environmental Sciences, Institute of Agricultural and Environmental Research and Technology (IITAA). Rua Capitão João d’Ávila, 9700-042 Angra do Heroísmo, Açores, Portugal. Macaronesia islands’ invasive plant use in animal feed or composting may bring economic and environmental benefits to the region. Arundo donax, Pennisetum setaceum, Agave americana, and Ricinus communis, present in the three archipelagos (Canary, Azores and Madeira), were characterized chemically and biologically. A. donax and P. setaceum showed elevated crude protein (CP) content, 13.25 and 16.33 DM%, respectively, and extremely high NDF values, 75.87 and 80.83 DM%, with a DM digestibility of 55.02 to 59.77%. A. americana showed a low NDF value (22.78 to 27.94 DM%) and a very low CP value (4.24 to 5.61 DM%). However, its DM digestibility was high (79.89 to 86.33%). R. communis presented the best values for CP (24.62%) and NDF (26.56 DM%), however, due to the presence of toxic substances (ricin), it cannot be easily used in animal feed. The P. setaceum and R. communis were found to be the least gas-producing forage, with A. americana being the major producer. To increase these plants’ value for animal feed, treatment with urea or NaOH to A. donax and P. setaceum, and enrichment with nitrogen to Agave is proposed. Due to its toxic properties, R. communis must be used in composting. This work has been funded by Ecofibras Project (MAC/4.6d/040) and INV2MAC project (MAC2/4.6d/229), and by FEDER funds via Operational Programme Competitiveness Factors– COM-PETE and by Regional Funds from Secretaria Regional do Mar, Ciência e Tecnologia.
