National Bureau of Statistics of China
August 25, 2021
According to the sampling survey of early rice harvesting by on-site measurement, the sown area, yield per unit area and total output of early rice in China in 2021 are estimated as follows:
The total sown area of early rice was 4,734 thousand hectares (71,010 thousand mu), which decreased 16.6 thousand hectares (249 thousand mu) over last year, with a decrease of 0.4 percent.
The yield per unit area of early rice was 5,918 kg/ha (395 kg/mu), increased 173.0 kg/ha (11.5 kg/mu) over last year, with an increase of 3.0 percent.
The total output of early rice was 28,020 thousand tons (56 billion jin), increased 723 thousand tons (1.45 billion jin) over last year, with an increase of 2.7 percent.

Explanation on the Early Rice Output Survey
1. Survey Coverage
The data released by NBS on the early rice output, were estimated from the sample survey taking the province as the total population.
Sample survey and on-site measurement conducted in the counties (cities) are organized by the Survey Organizations of NBS at provincial level.
2.Survey Sample
The sample survey on early rice output consists of sown area sample survey and yield per unit area sample survey.
The sample survey on early rice sown areas is conducted in more than 3,000 sample land segments selected in national survey counties (cities). The early rice sown areas at province level is estimated based on the basic survey data.
The survey on yield per unit area of early rice is estimated by on-site measurement, which is conducted in the selected 20,000 small sample plots from almost 7,000 sample land segments selected from survey villages in national survey counties (cities).
3. Output Measurement Method
The on-site measurement refers to the investigators in the grass roots, before harvesting, in accordance with System of Statistical Report for Agriculture, Forestry, Animal Husbandry and Fishery, stepping in the field and estimating the output of planting land plots one by one, and ranking them by output, then selecting a certain segment and marking them out. During harvesting period, investigators of the survey organizations at county level or assistant investigators will put sample and select sample on-site, and then estimate the yield per unit area through threshing, drying, water-checking, weighting and other steps on the selected land segments. The survey organizations at province level estimate the provincial (municipal) average yield per unit area based on the data from the selected land segments.
The outputs of early rice are multiplied by the sown areas from sample survey and the yield per unit area.
