Description
<p>We dressed the buckwheat (Fagopyrum esculentum Moench) seeds with the calcium peroxide agent and investigated the effects on emergence under excess-moisture and the suitability of dressed seeds for mechanical sowing. The coating amounts of calcium peroxide were 0.5, 1, 1.5, and 2 times the weight of the buckwheat seeds. The flooded treatment was performed for 1-5 days from the day of sowing, and the next test was performed immediately after sowing and 1 to 4 days after sowing, each for 24 hours. The emergence rate was higher in seeds coated 1.5 and 2 times the weight of buckwheat seeds than in the uncoated ones. In particular, the emergence rate in waterlogging for 4 or 5 days was more than twice that of uncoated excess-moisture. It was clarified that a 1.5-and 2 times coating promoted emergence under excess-moisture conditions, and it was suggested that the decrease in yield due to delayed budding could be prevented. In contrast, the emergence rate was significantly lower in those coated 0.5 times the weight of buckwheat seeds than in the uncoated ones. When the coated seeds were dropped from the four types of sowing machines, the coating with 2 times the weight of buckwheat seeds showed the least amount of calcium peroxide released on any machine.</p>
