Far away from Utah State to do research at NCHU

This summer from 29th May to 31st July 2016, I have had a productive and enjoyabletime working with faculty and students at National Chung Hsing University (NCHU). This visit was intended forconducting my research entitled “Simulated Rice Growth and Yield under Low Temperature and Climate Variation in Taiwan’ with Prof. Yuan Shen, College of Agriculture. My supervisor Assoc. Prof. Simon Wang was also in Taipei this summer so he and I had visited a couple of times for discussion and networking. The close proximity of NCHU and Taiwan Agricultural Research Institute (TARI) at Taichung allowed me to interact with researchers at TARI who provided rice and weather data as well as valuable informationto support my work. Needless to say, this trip exceededmy expectationsin terms of successful research collaboration.
My investigation involved climate analysis and application of ORYZA simulation model for rice grown at TARI, Miaoli, Chiayi and Yilan. With guidance from Prof. Shen and Dr. Ming-Hwi Yao (TARI), I found frequent and pronounced cold spells with temperatures below 10 oC during November to March, especially in Miaoli. This low temperature threshold may cause damage in several crops including rice, pear, strawberries, other fruits and vegetables. Rice grown in the first season (Jan-Jul) may have been damaged from unusually cold-wet weather during tillering to panicle initiation stages. Cold-dry conditions occurred in the grain filling stage of the second cultivation (Jul-Dec). During my visit, I have completed the calibration and test of ORYZA modelfor 2 specific Taiwanese varieties (TNG67 and TCS10). The impacts of low temperature and climate variation on rice growth and yield will be further simulated by ORYZA model.
Besides my research progress, it was worthwhile for me to learn a new culture, make new friends and enjoy Taiwanese scenery. Taichung is centrally located which meant good transportation and easy exploration other cities of Taiwan.
Thank you for providing a very pleasant university environment includingan office and facilities from International Master Program of Agriculture (IMPA), Dept. of Soil and Environmental Sciences,and accommodations arranged by Office of International Affairs. Lastly, thank you for the opportunity to participate in this research exchange visit between Department of Plants, Soils, and Climate, USU and NCHU.
