Abstract: In order to answer the question of potential grain productivity in Henan Province, this paper estimated potential grain productivity under the experimental conditions using data of soil test and fertilizer demonstration test and evaluation results of cultivated land fertility in Henan Province. The results showed that the average values of the highest yields of wheat, corn, rice under the experimental conditions of using data of soil test and fertilizer demonstration test were 4726.2, 5817.6 ,5409.15 kg/hm2, respectively. The potential grain productivity that Henan could achieve was 74.8727 million tons, increasing by 35% from the present level.
