Development and Test of Grain Mass Flow Monitoring System Based on Pressure Sensor

Research Article of American Journal of Agricultural Research Development and Test of Grain Mass Flow Monitoring System Based on Pressure Sensor Delei Tan1, Duanyang Geng1*, Huabiao Li1, Haolin Yang1, Yanchun Yao1, Yangmeng Zhang2 1School of Agricultural Engineer and Food Science, Shandong University of Technology, Zibo 255000, China; 2Shandong Agricultural Machinery Technology Promotion Station, Ji’nan 250100, China. In view of the technical development requirements of digital agriculture and the requirement of operation parameter regulation in the operation process of grain harvester. An on-board grain mass flow monitoring system based on pressure sensor was developed. The mathematical model of grain mass and grain flow pressure was established, which realized the real-time measurement, display, and storage of grain dry/wet quality information during the operation of grain harvester. An indoor bench test was carried out with the independently developed grain flow monitoring test bench. The results showed that the output error of the grain mass flow monitoring system was less than 4.25% under the conditions of indoor bench test, which meets the accuracy requirements of grain flow monitoring and provides the decision basis for variable seeding and variable fertilization.

Effect of adding graded levels of lablab forages on fermentation characteristics of Brachiaria silage

Research Article of American Journal of Agricultural Research Effect of adding graded levels of lablab forages on fermentation characteristics of Brachiaria silage Nviiri Geofrey1*, Okello Horace1, Turyagyenda F., Laban1 1Ngetta Zonal Agricultural Research and Development Institute, P.O. Box 52, Lira, Uganda Ensiling as a method of forage feed conservation is the most appropriate in conserving of crude protein (CP) enhanced forages for sustainable dairy production. This is attributed to the fact that with this method, protein dependent lactic acid bacteria (LAB) hydrolyze water soluble carbohydrates (WSC) into short chain volatile fatty acids (VFAs) which are precursors for milk synthesis while the proteins buffers the excessive organic acids to produce more acetate and propionate. The study therefore aimed at assessing the quality of Brachiaria silage which was protein supplemented with graded levels of lablab forage. To achieve this objective, wilted Brachiaria forage (Brachiaria hybrid cv Mulato II) was collected, wilted and ensiled with and Lablab purpureus forages at inclusion levels of 0%, 10%, 20%, 30% Lablab purpureus forage.  The resultant 4 treatments were assessed in a completely randomized design in 3 replicates. All silages were prepared using plastic jar mini-silos to laboratory scale and then incubated at room temperature (±30°C) for 45 days. After the 45 days, chemical analysis for quantification of water soluble carbohydrate (WSC), none protein nitrogen (NH3-N), Acid detergent fiber (ADF), Neutral detergent fiber (NDF), pH, in-vitro organic matter digestibility (INVOMD), acetic acid, lactic acid and propionic acid composition were conducted. The results indicated that; none protein nitrogen, acetic acid and propionic acid composition decreased in quadratic trends with increasing legume forage inclusion to minimum values of 5.8, 48.0 and 0.7g/kg at 14.7, 1.8 and 6.0% inclusion levels of lablab forage, respectively. On the other hand, following a quadratic trend, WSC composition decreased with increase in lablab forage, ...

Identifying the Topographic Slope Characteristics Most Preferred By Wild Olive Trees in Al-Bahah Region, Saudi Arabia

Research Article of American Journal of Agricultural Research Identifying the Topographic Slope Characteristics Most Preferred By Wild Olive Trees in Al-Bahah Region, Saudi Arabia Abdullah Saleh Al-Ghamdi Department of Biology, College of Sciences, Al-Bahah University, P.O. Box 400, Al-Baha 31982, Kingdom of Saudi Arabia. The aims of this research were to identify the topographical slope characteristics most preferred by wild olive trees in the Al-Bahah region. This study successfully identified the degree of the slope preferred for wild olive groves. The findings revealed that the majority (72.9%) of wild olive trees in Al-Bahah region occupy slopes of 5–30°. However, the patterns in Qelwa and Al-Mekhwah districts are a bit different where most of the wild olives were found on steeper slopes of 20–40°. This is probably because these sub-regions have a medium to steep slope, descending gradually toward the west, the altitudes ranging from 200 (400) to 2001 and 2200 m west of Al¬-Bahah city and Uwera, and between 2000 and 2100 m west of Baljurashi. The results further depicted that the wild olive with the medium-large crown diameter mostly occupied the gentler slopes of 0–25° compared to those with small crown diameters at steeper slopes of 5–35°. This indicates that the wild olive trees grow better on gentler slopes. These findings can be regarded as theoretically revealing the potential landform suitable for olive plantation. As a basis for olive plantation site suitability, these factors are the essential prerequisites to be considered. However. In addition, it is obvious that site suitability is subject to the temporal dynamics of environmental variables.

Research Status of Power Allocation of Combine Harvester

Review Article of American Journal of Agricultural Research Research Status of Power Allocation of Combine Harvester Ping Jiang, Aoqi Zhang, Yujie Deng, Huawei Liu, Haoze Li, Guohai Zhang* School of Agricultural Engineering And Food Science, Shandong University of Technology, Zibo, 255000, China. The development of combine harvester has greatly promoted the development of global agricultural mechanization, In this paper, a large number of research results related to power allocation of combine harvesters were collected, The development status of combined harvester transmission system and power test system is summarized through analysis and selection, It is found that there are few researches on the power distribution of the combine harvester, so it is necessary to further study the related research of the combine harvester. Fund project: The project of the agricultural machinery equipment R&D and innovation plan in Shandong Province(2016YF026,2018YF006); The project of the Talent Team Cultivation Program for Superior Disciplines of Universities in Shandong Province(2016-2020) Keywords: Combine harvester; Transmission system; Power test system ...

Construction of GIS-based Agricultural Machinery IoT Service Platform

Review Article of American Journal of Agricultural Research Construction of GIS-based Agricultural Machinery IoT Service Platform Haibo Sun1, Huawei Liu1, Keying Li1, Ping Zhang1, Yujie Deng1, Guohai Zhang1* 1School of Agricultural Engineering And Food Science, Shandong University of Technology, Zibo, 255000, China. In recent years, as the information technology becomes mature gradually and the modernized agriculture develops rapidly, the important role of agricultural mechanization in the development of the Internet era has gradually become prominent. As an important part of modernized agriculture development, the agricultural mechanization is also facing management problems caused by the information technology in the Internet era. The information shows new characteristics in the development of agricultural mechanization in the Internet era, such as rapid increase in the amount of information, faster data transmission and processing, more diverse data acquisition and processing methods, more and more complex technologies involved in information processing, and more and more extensive fields. As the information becomes diversified, complex and massive, the traditional agricultural machinery service management model shows greater limitations, such as low management efficiency, backward management methods, and low quality levels, etc.. The GIS technology has brought unprecedented development opportunities for the development of agricultural informatization. It plays an important role in promoting the improvement of agricultural machinery informatization to develop the agricultural machinery IoT service system by using the GIS technology.
