Nongsaroo's cultivation guidelines for Job's Tears explain that the plant can germinate at temperatures above 15°C , and that excessive planting density can increase the risk of etiolation, lodging, poor ventilation, and leaf blight. While general planting examples suggest a furrow spacing of 60 cm and a plant spacing of 30 cm, these are merely general guidelines and should not be applied as fixed standards specific to different varieties or regions. ( Nongsaroo )

As the Rural Development Administration advises that the prevention of contamination by toxic molds and mycotoxins occurring on the ears of miscellaneous grains such as sorghum, millet, and Job's tears is a separate management target, it is necessary to include a separate field for mold and toxin verification in the Job's tears Quality Dataset. ( Rural Development Administration )

Plant Identity

The Agricultural Genetic Resources Center registers the Job's Tears resource under the Korean family name: Poaceae, English family name: Poaceae, English crop name: job's tear, and scientific name: Coix lacryma-jobi var. ma-yuen. ( Seed Bank )

Product Master

The Agricultural Genetic Resources Center has numerous bred and introduced varieties, such as Aewon Yulmu, Pungseong Yulmu, Sanggang Yulmu, Daecheong Yulmu, and Yulmu No. 1, registered separately, so varieties are not simply consolidated into a single 'Yulmu'. ( Seed Bank )

Nongsaroo advises seed disinfection before sowing, as leaf blight and smut can be transmitted through seeds, and explains that soaking also serves to improve germination rates. It also suggests a germination temperature of 15℃ or higher for Job's tears. ( Nongsaroo )

In the harvesting techniques of Nongsaroo, the optimal time for harvesting is described as when the leaves and stems of Job's tears turn yellow and the seeds inside the fruit return to their characteristic color, suggesting that this generally corresponds to late September to late October , depending on the region. ( Nongsaroo )

The Rural Development Administration advises that preventive management is necessary to minimize contamination by toxic molds and toxins in the ears of miscellaneous grains, including Job's tears. Therefore, quality is not determined solely by visual inspection of the raw grain; instead, the decision regarding mycotoxin testing is made based on the buyer and product type.

Although it is confirmed that statistics on the production status of specialty crops are operated on KOSIS, arbitrary figures are not included because the nationwide cultivation area and production volume of Job's Tears alone for 2026 were not finalized using the same base year and unit during the drafting stage of v1.0. ( KOSIS )

In its 2020 research achievements, the Rural Development Administration disclosed the sequencing of the 1.28 Gb genome and 39,574 genes of the domestic variety *Johyeon-yulmu* , and also presented research results on genes related to coixol biosynthesis. This demonstrates that *Yulmu* is being managed not only as a simple miscellaneous grain but also as a target for research and material development. ( Rural Development Administration )

Trade Management

Since the classification of Job's tears in international trade may vary depending on the product condition and whether it is for food, seeds, or medicinal use, the HS Code is not determined without confirming the detailed product name in the current Korea Customs Service HSK.

Latest import/export volume, importing country, exporting country, and customs clearance unit price of Job's Tears:  To be entered later after verification of official raw data from the Korea Customs Service.

Job's tears raw grain, polished Job's tears, powder, tea, and herbal raw materials are not aggregated into a single statistic.

Utilization of by-products

Review Area:

Food materials · Fermentation · Feed · Compost · Biomaterials · Extracted raw materials · Waste reduction

However, when converting Job's tears by-products into food, functional, pharmaceutical, or cosmetic materials, the origin, safety, ingredients, relevant laws and regulations, and official test data must be verified.

PRP — Product Research Profile

While the Rural Development Administration's research on the Johyeon Job's Tears genome and coixol-related biosynthetic genes can serve as the official research basis for the high-value material PRP,  research-stage evidence is distinguished from commercial claims of efficacy and functionality . ( Rural Development Administration )

Nongsaroo explains that excessive planting density during Job's tears cultivation can increase the risk of excessive growth, lodging, and leaf blight, and advises in separate harvesting techniques that lodging leads to a significant reduction in yield. Therefore, planting density → plant height → lodging → yield → marketability are managed as the core Problem Relationship for Job's tears. ( Nongsaroo )
