Crop model inputs and base results for wheat and rice yields in Nanjing

	Weather data*	Sow date	Harvest date	Mean yield for base model†, kg/ha
Wheat	1969–1979	November 9	June 8	4,053
Rice	1970–1979	May 10	September 25	12,138

^*Input weather data consisted of averages of observations made during the indicated years. The data were obtained from Nanjing Agricultural Sciences (courtesy of Jin Zhiqiang). 

^† Base model represents the simulation using 100% of the observed total surface solar irradiance.
