Hwasun-gun Urges Timely and Proper Amount of Fertilizer Application for Rice Panicles

Producing High-Quality Rice by Timely and Proper Application of Rice Panicle Fertilizer

On the 17th, Hwasun-gun, Jeollanam-do, announced a request to apply panicle fertilizer for rice at the right time and in the right amount to ensure stable production of high-quality rice.

Panicle fertilizer is applied before the rice panicle emerges from the stem to promote full grain development.

For general cultivation, the appropriate time for application is about 25 days before panicle emergence to ensure stable production, while for high-quality cultivation, 15 to 18 days prior is suitable. The effect of use is reflected in a good grain-filling rate.

If panicle fertilizer is applied too early, the rice may lodge, and if applied late, after panicle emergence, the high nitrogen content increases the risk of neck blast disease, making timely application important.

For single cropping, the optimal period is from the 18th to the 25th of this month, and for double cropping, it is around the 29th to the 5th of next month.

The recommended amount is 11 to 12 kg per 300 pyeong based on specialized compound fertilizer NK, and for dark green paddies, 5 kg of potassium chloride is recommended.

Also, in paddies where slow-release compound fertilizer has been used as basal fertilizer, panicle fertilizer should preferably not be applied.

An official from the County Agricultural Technology Center stated, “Due to the recent long rainy season, mid-season drainage was not smooth, so overuse of panicle fertilizer may cause lodging. Therefore, it should be used at the right time and in the right amount. Additionally, water should not be lacking in the paddies for up to 10 days after panicle emergence, and water filtering and draining should be done to enhance root vitality.”
