MESSAGE In our Country, agriculture supports more than 60% of the population. Around 51% of India’s geographical area is under cultivation. Major shares of its GDP comes from agriculture sector. Government recently launched some major schemes like crop insurance, per drop more crop, Rashtriya Krishi Vikas Yojna to enhance the productivity of the crops. Initiatives like organic farming and increase in the production of pulses are also been taken. Geographical Information System (GIS) plays a vital role to use the latest technologies useful for the decision makers can visualize all the farmlands with their allied information and current situation on one click. The tasks like yield estimation and crop damage assessment done by traditional means take month or two and a whole lot of manpower to complete the work. By using Geospatial technologies, the same task can be completed within half or even in lesser time frame with minimum number of resources and high accuracy. Balancing the inputs and outputs on a crop farm is essential to its success and cost- effectiveness. The capability of GIS to study and envisage agricultural environments and workflows has proved to be favourable to those involved in the farming industry. While natural inputs in farming cannot be measured but, can be better understood and managed with Geospatial applications such as crop yield estimates, soil amendment analysis, erosion identification and remediation. The National Conference on Geospatial Technologies in Agriculture (NCGTA-2020) is to focus the attention of national policy makers, academicians in agricultural sector and industry-leaders throughout India on the vast opportunities in the area of Geospatial Applications and develop strategies for harnessing the same in a sustainable manner. The conference will provide a forum for establishment of liaison and intellectual co-operation between key stakeholders for development of sustainable practices in appropriate use of agriculture sector. i In this context, the NCGTA-2020 to be held at NAARM, Hyderabad is being organized by Association for Management of Agricultural Research and Agripreneurship (AMARA) in collaboration with NAARM during 20 -21st February, 2020, with its theme will enrich the knowledge for the conservation of agricultural resources. I am sure that this conference will bring new ideas and information and latest developments for the benefit of the researchers and farming community. I wish all success for the conference (Ch. Srinivasa Rao), Director, NAARM & President, AMARA ii MESSAGE Today Geographical Information System (GIS) in agriculture helps farmers to achieve increased production and reduced costs by enabling better management of land resources. The risk of marginalization and vulnerability of small and marginal farmers, who constitute about 85% of farmers globally, also gets reduced. Agriculture using Geospatial Technologies enable the farmers to map and project current and future fluctuations in precipitation, temperature, crop output etc. Agricultural mapping is day by day becoming crucial for monitoring and management of soil and irrigation of farmlands. It is facilitating agricultural development and rural development. Accurate mapping of geographic and geologic features of farmlands is enabling scientists and farmers to create more effective and efficient farming techniques. As farmers are able to take more corrective actions in the form of better utilization of fertilizers, treating pest and weed infestations, protecting the natural resources etc., we are bestowed with more and higher quality food production In the light of the global focus on GIS technology applications in agriculture, it is very timely and appropriate that Association for Management of Agricultural Research and Agripreneurship (AMARA) and ICAR-NAARM organizing a National Conference on Geospatial Technologies in Agriculture (NCGTA-2020) during 20 -21 February, 2020. I hope the conference would provide a platform to deliberate on the issues confronting the agricultural biodiversity and evolve innovative approaches for their conservation and utilization. I wish the National conference grand success (S.K. Soam) Joint Director, NAARM & Vice President, AMARA iii iv Preface The agricultural sector is the mainstay of the rural Indian economy around which socio-economic privileges and deprivations revolve, and any change in its structure is likely to have a corresponding impact on the existing pattern of social equality. No strategy of economic reform can succeed without sustained and broad-based agricultural development, which is critical for raising living standards, alleviating poverty, assuring food security, generating a buoyant market for expansion of industry and services and making a substantial contribution to the national economic growth. Sustainable agricultural production depends on the judicious use of natural resources (soil, water, livestock, plant genetic, fisheries, forest, climate, rainfall, and topography) in an acceptable technology management under the prevailing socio-economic infrastructure. Geospatial Technology plays an important role in the rapid economic growth and social transformation in developing countries. The future growth in agriculture must come from new technologies which are not only cost-effective but also in conformity with natural climatic regime of the country; technologies relevant to rain-fed areas specifically; continued genetic improvements for better seeds and yields; data improvements for better research, better results, and sustainable planning; bridging the gap between knowledge and practice; and judicious land use resource surveys, efficient management practices and sustainable use of natural resources. The National Conference on Geospatial Technologies in Agriculture (NCGTA-2020) is being organized to provide a central issue in agricultural development is the necessity to increase productivity, employment, and income of poor segments of the agricultural population, and by applying GIS in agriculture, this situation can be addressed. GIS tools and online web resources are helping farmers to conduct crop forecasting and manage their agriculture production by utilizing multispectral imagery collected by satellites. The ability of GIS to analyse and visualize agricultural environments and workflows has proven to be very beneficial to those involved in the farming industry. v GIS has the capability to analyse soil data and determine which crops should be planted where and how to maintain soil nutrition so that the plants are best benefitted. We are delighted to bring this conference book of abstracts, this souvenir covers the plenary lectures, lead papers and invited lectures in different sessions. A total of 110 abstracts received for presentation are accommodated under different sessions, keeping in view the overall theme of the conference. The NCGTA-2020 organizing committee is thankful to all the contributors who have shared their findings, knowledge and ideas through this publication for the benefit of the farmers and the scientific community. We take this opportunity to place on record our profuse indebtedness to ICAR, and NAARM their sponsorship and all the help and cooperation extended for bringing out this publication.
