| 内容記述 | The authors tried to study the early and late croppings of rice plants in 1954. The plants were sown and cropped either earlier or later as compared with the ordinary planting. Several varieties were tested for determing their adapt-abilities for each planting, so that their yields and growth habits due to the both conditions were examined. Interrelations between yields and some characters of the growth were made clear and the following results were obtained. A) In the case of the early planting, yields of tested varieties were significantly correlated with the duration of the growth (days from seeding to maturation) and number of ears per plant. From these results, early maturing varieties which head later and have larger number of ears per plant, may be greater yield and be suitable. These varieties belong to the so-called types bearing many panicles; such as EIKO which were cropped till the middle of August and NORIN No.1,HASHIRI-BODZU, FUJISAKA No.5,HAKKODA which were yielded till the end of the month. B) In the case of the late planting, ear length, consequently ear weight, were found to be highly correlated with yields, in contrast to the early planting. So it may be said the following varieties of all grades of maturation which belong to the so-called types bearing heavy panicles, are most fitted; WAKABA, GINGA No.2 which matured till the middle of November and OBANAZAWA No.5,HARUTA-ASAHI, HASHIRI-BODZU, AYANISHIKI which were cropped at the end of this month. C) As the general growth habits, we observed that days from transplanting to maximum tillering stage were made longer and those from heading to maturation were shortened by the early planting and vice versa in the case of the late planting. Moreover, the early planting did not make plants discolour even though they reached to maturation, and the late planting produced somewhat excessively elongated seedlings to be transplanted. From these, some cautions and devices must be paid to the cultural operations. | |||||
