Dear Authors and (Online) Participants of MMTES-III, International Scientific Conference Mathematical Modeling of Technical and Economic Systems in Agriculture III (MMTES III-2020) was successfully held online on Dec 10-11, 2020 in at the Department of Mathematical Modeling and Computer Science with organizational and technical support of the Center of Applied Scientific Research (location of organizers - Volgograd, Russian Federation). Due to COVID-2019 and the pandemic-related nationwide lockdowns and other coordinated restrictive measures, the organizers decided to hold a conference in a virtual format with the organization of access for all participants to the presented reports with comprehensive discussion for ensuring the event at a high scientific level. The safety and well-being of all conference participants is our priority. The COVID-19 is unpredictable, so conference postponement met uncertainty, while many scholars and researchers want to attend this long-waited conference and have academic exchanges with their peers. But I want to note that there are no barriers to science, and we continue to work on our research areas remotely, using modern technical means.

The conference was held virtually for 2 days (Dec 10-11, 2020) including keynote and invited speeches, authors’ presentation session. The event was held online using Zoom communication platform for synchronous conversation. The conference was organized as a large-scale online meeting of participants in topical sessions with the opportunity for speakers to provide regulated demonstrations of slides and video files according to the approved technical program. Each speaker had 15 min presentation and 5 min Q&A session. There were always 20-25 participants in the network. During the online presentation, participants discussed more than 50 questions on the problems of modeling technical and economic systems in the agro-industrial complex. Participants of the conference were from the leading institutions of Russian Federation, Uzbekistan, Germany, Republic of Belarus (All-Russian Scientific Research Institute of Hydraulic Engineering and Reclamation named after A.N. Kostyakov, Namangan Engineering and Technology Institute, Technical University Of Munich, All-Russian Research Institute of Irrigated Agriculture, Belarusian State Agrarian Technical University, Volgograd State Technical University and others), dealing with problems of increasing agricultural productivity. The outstanding performance of all the presenters made this conference truly spectacular.

Main topics of the conference were:

1. Mathematical modeling of socio-technical and organizational-economic systems.

2. Modeling of natural-technical and agro-ecological processes.

3. Artificial intelligence and neural network technologies in agricultural production.

4. Modeling of innovative and technological processes in agricultural engineering.

5. Modeling of reclamation and environmental technologies in agricultural production.

6. Resource and technological support for the production of agricultural products.

7. Seed production, plant breeding and biotechnology.

8. Innovative technologies in solving economic problems in the agro-industrial complex.

9. Modern electrical technologies, electrical equipment and power supply in rural areas.

This volume of IOP Conference Series: Earth and Environmental Science (EES) is a compilation of the accepted papers in MMTES-III and represents contributions that were presented in the conference. I would like to thank all of the conference sponsors and partners who made conference possible. My special thanks go to our speakers as well as all the authors for sharing their latest research results.

Looking forward to meeting you during MMTES IV-2021!
