Visualization Analysis of Research on Rice with Fertilizer from the ‘Agronomy’ Category based on Citespace

In the present study, a total of 1757 documents of article and review relating to rice with fertilizer from the ‘agronomy’ category were analysed based on the Web of Science during the period 1990– 2018. Using CiteSpace software, visualization analysis on co-authors, co-institutions, author cocitation, citation analysis and keyword co-appearance network was performed. It was observed that the number of publications has grown rapidly over the past years. The top five most productive authors were Ladha, J. K. (India), Dobermann, A. (UK), Peng, S. B. (China), Fageria, N. K. (Brazil) and Haefele, S. M. (Philippines). India was the most productive country, followed by China, USA, Japan, Philippines and Australia. The top three institutions were International Rice Research Institute in Philippines, Indian Council of Agricultural Research (ICAR) and Chinese Academy of Sciences (CAS). The top 15 keywords were rice, yield, soil, nitrogen, management, fertilizer, growth, system, wheat, grain yield, lowland rice, phosphorus, plant, productivity and use efficiency, each cited more than 100 times. This article highlights the status and future trends of research on rice with fertilizer.
