The characteristics of direct-sown rice and measurement of increased yield


, : The characteristics of direct-sown rice and measurement of increased yield. China Rice ( 4): 30-33

In field trials in Zhejiang, direct sown rice crops showed an increased number of tillers compared with transplanted crops and at 2 sites where the number of effective tillers were increased the numbers of grains/panicle were decreased. At 1 of these sites the yield was increased by direct sowing from 392 to 406 kg/mu while at the other yield was decreased from 612 to 568 kg. For direct sown crops to be successful it is necessary to ensure that a full stand of plants is obtained.
