Abstract

Abstract: Buckwheat variety Ningqiao 1 was selected as material to study the effects of different planting densities in different years on agronomic traits, seed setting rate and yield of buckwheat. The results showed that in the 2014 growth season with more rainfall, with the increase of density, the plant height, stem diameter and main stem section number increased; the seed number per plant, grain weight per plant, thousand seed weight, and seed setting rate showed a trend of decrease; and the yield increased. In the 2015 and 2016 growth season with less rainfall, with the increase of density, the number of main stem section, seed number per plant, grain weight per plant and thousand seed weight increased at first, then decreased; the seed setting rate declined; and the yield increased at first, then decreased. To get a high yield, the planting density of 60 000 plants/667 m² is suitable for buckwheat planting in the southern mountains area of Ningxia.

Key words: buckwheat（Fagopyrum esculentum Moench.）, planting density, agronomic trait, seed setting rate, yield
