In the present century, the need to provide food security for the growing population of the country, the importance of maintaining human health and the environment, as well as the need to continuously increase the productivity of inputs, has made the use of new technologies in the production of agricultural products more necessary. One of the new technologies is Intelligent agriculture. This paper has tried to present the importance of remote sensing technology as one of the most important parts of intelligent agriculture, namely data collection and recording. Also, the types of platforms and sensors that have been introduced in remote sensing studies and their applications in agriculture, as well as the advantages and limitations of each method are described.

Typically, the basis of scientific articles assessment in scientometrics analysis is the citations count that an article receives. However, in such citation analyzes, differences in scientific disciplines, type and age of articles, and disciplines citation behavior in general are not considered. To deal with this problem, it is necessary to normalize the citation indicators. Normalization can be considered as a topic that deals with correction of citation indicators between scientific fields. Using normalization methods makes comparative evaluations of different scientific fields more accurate and fair. The purpose of this article is to explain the concept of field normalization of citation indicators, their application, types of field normalization methods (including cited-side normalization and citing-side normalization), and to examine some of the challenges associated with their use. This article provides some recommendations for the use of field normalization indicators such as FWCI by research institutions and universities. . . . . .

Concepts and phenomena such as data-driven, metadata, semantic web, and big science point to a process that highlights the importance of managing data, information, and knowledge cycles in institutions, and the professtion associated with them. At the same time, these terms are somehow the product of the development of ICT and their applications in the management of individual and organizational actions.In this article, the above concepts and phenomena were described in relation to each other and in interaction with some goals and tasks. Success in these areas requires extensive cooperation of individuals and institutions in the management of financial, technical, and human resources. It also needs strategies that requires the cooperation of individuals and institutions, because it is time consuming and costly, and requires different skills and professions. The ICT integrated all of these and and their results. Another purpose of this article is describing the importance of studying information,knowledge and technology management for optimizing the knowledge cycle with emphasis on some well-known examples.

More than 50 percent of the arable land of Iran is at high risk of drought, and this has sounded the alarm for those concerned about food security to try to adopt effective strategies to deal with this issue. In this paper we aimed to present some agronomic and breeding strategies, and also smart technologies for monitoring and mitigating the drought impacts on plants, those have proved their positive effects on maintaining the yield of various plants in the country according to the numerous internal research. Accurately setting planting windows and density using decision support systems (DSS) and growth and simulation models, selecting proper cultivars, especially newly bred resistant idiotypes with desirable root and stomata characteristics, seed priming and coating methods, biofertilizers especially Arbuscular Mycorrhizal Fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) and also soil modifiers and amendments such as zeolites and organic or polymeric superabsorbent are among useful agronomic and breeding strategies to maintain crop yield under drought condition. More importantly, Precision Irrigation (PI) through continuous monitoring of temperature, humidity, and rainfall using various technologies such as Internet of Things (IoT), wireless sensor networks (WSN) and cloud computing as well as remote sensing tools such as unmanned aerial systems equipped with thermal sensors have made a significant contribution to increasing plant performance in areas faced with water crisis. The proposed methods can be obtained according to their suitability with the agricultural systems and farmers' conditions based on available resources (labor, land, and affordability).

One of the current priorities of libraries and information centers of research organizations is the digitization of scientific resources. There are many valuable indigenous scientific resources in these organizations that are not currently usable in existing network environments. These resources need to be digitized and properly organized so that they can be exploited in the web and remote networks.The Agricultural Research, Education and Extension Organization, as one of the largest research organizations in the field of agriculture and natural resources, seeks to collect and organize information in such a way that in the shortest possible time, researchers, faculty members and producers and farmers in the agricultural sector Use it to perform their activities optimally. Likewise, digitization of scientific resources, especially indigenous scientific resources, is one of the important priorities of this organization. In this article, we have tried to point out the necessity of developing a digital library in this organization and then provide the necessary requirements and general recommendations in this field.
