Abstract：In order to obtain the optimum sowing date of buckwheat ,two cultivars (Wensha and Xiqiao 1) were selected to investigate the grow th period and its structure ,agronomic characters , dry matter accumulation ,yield and yield components of buckwheat .The results showed that ,with the delaying of planting date ,the days from sowing to emergence ,the days from emergence to blooming and the growth period of buckwheat were significantly shortened .The height ,stem di-ameter ,anthotaxy number ,branch number and stem node number increased at first and then de-creased with the sowing date delayed for both of the two buckwheat cultivars .With the delay of sowing date ,the dry matter weight was gradually increased at first and then decreased in mature period .The appropriate sowing date could improve the yield of buckwheat ,which increased at first and then decreased with the delay of seeding time .The best sowing date for Wensha and Xiqiao 1 was 12th March and 2nd March ,respectively ,which gave the highest yield ,1 776 .8 kg/ha and 2 696 .0 kg/ha ,respectively .
