Studies of Soaking Rice Seeds in Water During Cold Seasons Prior to Sowing Time.

[摘要] 1) This experiments has been carried out in order to clarify the various effects of continuous presoaking of rice seed from winter season up to sowing time. 2) The germination and viable seedling percentage decreased in treated plot and the rice seeds which died during the treatment period were found mostly in weak grains. 3) It was found that the seeds sown before 25th April, after the treatment, showed a remarkable increase in grain yield as compared to those sown without treatment. Bnt on the other hand reverse results were obtained, when the seeds were sown later than the above mentioned date. 4) The presoaking treatment might not be the only factor, responsible for the increase of grain yield, bnt the early and thin sowing should also be taken into consideration.
