Abstract

The effects of different drought degrees on growth and yield of rice Jia 58 and Yongyou 12 were studied. The results showed that the severe drought (field fracture 30 cm) induced the decrease of rice plant height, dry biomass and yield. The main causes of yield decrease were small spike and the decrease of seed setting rate.

Key words: rice; drought; growth; yield
