Effect of sowing time and seedling density on yield of Teyou 103

Effect of sowing time and seedling density on yield of the rice,Teyou103,in early and late seasons was studied.The result showed that sowing time and seedling density affected mainly the spike number and grains per spike.Thus,with moderate fertilization,Teyou 103 could be sowed in mid-February for the early crop and in mid-July for the late crop at a seedling density of 650,000 per hm2 in southern Fujian for the highest possible yield.
