The purpose of this study was to evaluate the H-index among researchers of the Agricultural Research, Education and Extension Organization (AREEO) and to investigate the relationship between their academic rank and bibliographic measures of research productivity.

This is a descriptive-applied research that has been carried out using a scientometrics approach. The study population consisted of 2125 faculty members in four categories: professors, associate professors, assistant professors, and instructors. The research organization's scientometrics system was used for data collection and Spearman correlation test was used to investigate the relationship between research variables.

The results showed that from 2125 faculty members 337 (15.86%) were female and 84.14% were male. The number of assistant professors was 1261 (59.34%) that is the highest frequency and only 2.4% of the population are the professors. The study population produced a total of 12734 articles that its 50.14% have been authored by professors and 73.51% by assistant professors. The average citations received were 626.82 for professors’ papers, 113.69 for associate professors’ papers, and 45.3 citations for assistant professors’ papers respectively. Also the mean H-index of the was 9.88 for professors, 4.39 for associate professors, 2.15 for assistant professors, and 0.72 for the instructors. According to the findings, there was a significant relationship between academic rank and three scientometrics indices. In addition, H-index of women was higher than men.

Investigation of the relationship between academic rank and H-index among faculty members of AREEO shows that there is a moderate correlation between them.

This paper presents the introduction of IoT and some of its applications in agriculture and also the technical challenges of developing IoT-based systems.The IoT depicts a technological world in which many objects are interconnected. An IoT-based object consists of main layers, including the perception layer, the network layer, and the application layer. The perception layer is used for data collection, the network layer for storing and analyzing information, and the application layer for sending a message to the operator and setting it up. Some of the technical challenges of IoT development are the limitations of the data gathering, saving data, networks, appropriate hardware for the agricultural area, and ensuring data integrity and security.The application of this technology in agriculture causes cost reduction, better management ,and increasing productivity. The IoT is developing rapidly. The high economic benefit of this technology is the main incentive for investors to invest in this field.

ResearchGate has the largest number of members and audiences among the scientific social networks. In order to investigate the level of participation and scientific activity, all 852 researchers' member of this network in the research institutes, national and provincial research centers affiliated to the Agricultural Research, Education and Extension Organization (AREEO), were subjected to study. Relevant data were obtained from the AREEO's scientometric database until 2019, as well as the altmetric data from their research activities in the ResearchGate network. The results showed that nearly one quarter of the organization's researchers are members of the ResearchGate network and their scientific activity has increased as their scientific rank. In this way, the participation of the researchers in scientific social networks will make increasing in their scientific activity and today knowledge access. This will result in additive productivity in the activities of the subsidiaries of the Agricultural Research, Education and Extension Organization.

Wind erosion is one of the most important desertification processes in arid and semi-arid regions. This process destroys lands, soil, water resources and more. Dust phenomenon is one of the most important consequences of wind erosion in Iran and worldwide and especially in the west and southwest of Iran. Therefore, the present study is based on a combination of field data, remote sensing, and climatology and physiography data, In order to identify internal dust generating centers in the western part of the country. Based on the statistical results, the maximum dust event was recorded for the study area during 2008, 2009 and 2012. On a monthly basis, May, June and July are the most dusty events. On an hourly scale, the maximum occurrence of dust occurs from 9 am to 6 pm local time. Tracing of inlet dust paths showed that during the warm period of the year most of the input dusts are in the northwest - southeast and west - east direction and in the cold period especially late in the south - north direction of the study area. Land use mapping and surveying changes indicate a decrease in water levels, vegetation cover, and land depletion in 2015 compared to 2000. These features, along with physiographic features such as high erosivity of the formations, presence of saline and marshy soils, low soil moisture, high variability of land use, identified potential areas and potential for dust generation in the target provinces.

Libraries rankings can be used to predict the level of the library, the type of resources purchased, the amount of budget allocated, the space needed, and even the possibility of removing or expanding a library. . For this purpose, 5 libraries were studied in order to rank the affiliated libraries of Research, Education and Agricultural Promotion Organization. A checklist consisting of 4 sections (Collection, Resource Organization, Services and Human Resources and Equipment and Equipment) and 33 criteria was prepared and implemented in the statistical database of affiliate units of the Organization. The results showed that only one library (1.16%) with a score above 600 was at level one and six libraries (6.97%) with a score above 300 were at the second level. 79 libraries (91.86%) rank third with a score of below 300. Not all libraries in the organization are in a good position and should be given more attention.
