 note = {Thinning is one of the important agricultural techniques to adjust the planting density, but few studies have showed for optimum timing of the thinning. In this study, we grew the radish (Raphanus sativus L. var. sativus) by planter in the air-conditioned room, and clarified the optimum timing of thinning. We set seven different conditions, such as presence or absence of thinning and different timing. The diameter, length, and fresh weight of radish root were compared among conditions. As a result, the following four points were clarified. (1) It is no significant difference in yield between the condition to thinning at the 90% coverage and the condition to thinning at earlier timing, which is carried out in customary cultivation. (2) When the thinning timing was delayed, the thickening growth was inhibited, and when it is further delayed, the rate of low-quality individual increased. (3) When the thinning was not done, each individual was remarkably suppresses hypertrophy of root. (4) Compared to the conditions that thinned out from densely planted condition, harvesting of large individuals can be expected compared to the condition that does not thin out by widening the sowing interval from the beginning., text, application/pdf},
