Abstract: The effects of sowing date and planting density on yield components of rice (Oryza sativa L.) variety Liangyou 3313 were studied. The results showed that the suitable sowing date of Liangyou 3313 in northwest Hubei province was the middle of April, and the planting density of 281 250 holes/hm2 was the most suitable under the condition of medium and high fertility level.

Key words: rice(Oryza sativa L.), Liangyou 3313, sowing date, planting density, yield component factor, effect
