Background: The leaves of the goji berry (Lycium chinense Mill.) are used as raw materials in processing and by replace fruits to some extent. The reason is that the leaves are cheaper, however, betaine content is higher than in the fruits. These experiments were conducted to determine the planting density and cutting height for producing a large number of leaves.
Methods and Results: The cultivar ‘Myeongan’ with many branches was used. When the shoot height reached 50 ㎝ - 70 ㎝, harvesting was possible four times a year. The time to next harvest was approximately 38 days after regeneration of new shoots. Leaf quantity was in the order of 1st ＞ 2nd ＞ 4th ＞ 3rd harvest. Insect damage occurred during the third harvest in late July and early August, therefore, eco-friendly control was necessary. The total yield was higher at the planting density 60 ㎝ × 30 ㎝ than that of 60 ㎝ × 20 ㎝ or 60 ㎝ × 40 ㎝. The yield at cutting for shoot height of 60 ㎝ was increased by 6.3 percent compared to that of 50 ㎝, At the cutting height of 70 ㎝, harvest was difficult owing to hardening of stems and thorns. Betaine content, an indicator component of goji berry, was not significantly different according to planting densities and cutting height.
Conclusions: The ideal cutting period to produce leaves of goji berry for processing is when the shoots grow to approximately 60 ㎝, and the leaves can be harvested 4 times a year. The dried-leaf yield was highest at the planting density of 60 ㎝ × 30 ㎝.
