Keynote: Using of beneficial soil microrganisms to improve the seed yield and quality of Phaseolus vulgaris in a reduced fertilization condition
Time : 10:00-10:30
Patrizia Cesaro is a researcher at the Università del Piemonte Orientale “Amedeo Avogadro”, Italy. She graduated cum laude in Biological Sciences at the University of Torino, she received a Specialization in Applied Biothecnology with an evaluation cum laude and finally she received PhD in "Environmental Science, internal waters and agroecosystems" at the University of Piemonte Orientale. Her research has been focused in plant science, she has a good expertise molecular biological techniques. Since 2011, Professor of Molecular Biology.
Phaseolus vulgaris is a legume able to form symbiotic associations both with arbuscular mycorrhizal fungi (AMF) and Rhizobium bacteria. Phaseolus vulgaris cv. Billò is an important and valuable crop widely cultivated in North-Western Italy. AMF are known to improve plant nutrition, in particular phosphorus and nitrogen acquisition, and hence seed quality. Rhizobium leguminosarum is a gram-negative bacterium, symbiont of various species of Fabaceae that is able to fix atmospheric nitrogen.
The aim of this work was to check, in field conditions, the possibility to improve bean seed yield and quality by means of inoculation with AMF and/or rhizobia under conditions of low fertilization. First fifteen different Rhizobium strains were isolated from root nodules or soil and characterized by molecular and biochemical traits. One of these strain was selected and used with AMF for a field trial. At harvesting, root nodulation and mycorrhizal colonization were assessed and seed quality parameters were evaluated.
Yield parameters and fiber content were not influenced by microorganism inoculation nor by the reduced fertilization, whilst protein concentration was higher in the seeds of Rhizobium-inoculated plants in combination or not with AMF. Starch concentration increased in the seeds of plants inoculated with rhizobia alone. Mg, K and Zn concentrations were positively affected by AMF, while Mn concentration was higher in the presence of Rhizobia.
In conclusion, an environment-friendly practice like low chemical fertilization can be associated to inoculation with soil microorganisms in order to improve bean seed quality.

Keynote: Integrated bio-cycles management for rehabilitation of degraded land by anthropogenic desertification in tropical ecosystem
Time : 10:30-11:00
Cahyono Agus was born in Yogyakarta on March 10, 1965. He is a professor at Universitas Gadjah Mada (UGM) Yogyakarta Indonesia. He earned a doctorate from the Tokyo University of Agriculture & Technology, Tokyo, Japan, in 2003. He served as head of the UGM University Farm (2008–2015), Chairman of the Tamansiswa Alumni Board (2016-2022), a member of Majelis Luhur Persatuan Tamansiswa, and the Education Board of Yogyakarta. He is an active reviewer for research, community development, scientific publications, and institutional development in Higher Education, Indonesia. Cahyono has published many scientific works in international seminars and journals and has been awarded several honors and copyrights from various agencies.
Miss-management and over-exploitation of natural resources caused accelerated anthropogenic desertification of the former tropical ecosystem. Open mining activities exposed toxicity materials and formed moist degraded desert land that could be the leading cause of severe anthropogenic local, regional, and global environmental degradation. Moisture deserted land in the tropical ecosystem has more limiting factors in the form of physical, chemical, and biological soil properties, which are more dangerous compared to deserts in temperate regions. The shifting paradigm from the extraction of natural resources to sustainable development concepts will facilitate shifting industrial activities for more smart, global, focus, productive, efficient, environmentally friendly, and futuristic programs. Synergism to genetic and environmental engineering will improve the success rate of land rehabilitation. Environmental site engineering on critically degraded land through land preparation, soil amendment, biofertilizer, plantation, and biological conservation could facilitate a better rehabilitation of mining land and have added value to the environment, economy, socio-cultural, and health aspects. The management of land resources (i.e., soil, water, mineral, air, and microclimate) and biological resources (i.e., fauna, flora, and human) by an integrated bio-cycle management is an essential strategy for productive and conservative degraded tropical ecosystems. Technical, socio-culture, and environmental site engineering contributes significantly to the initial sustainable development of land rehabilitation in a deserted tropical land.
