Industrial hemp is becoming more popular in the United States, but the best way to grow it for fiber is still unclear. There is an urgent need to develop agronomic practices that are specifically adapted to the local soil and climates.
Hemp yield and fiber quality vary based on soil type, fertilizer use, plant variety, spacing, and weather conditions. This means farmers need specific recommendations for their fields.
We studied how different row spacings (19 cm vs. 38 cm) and fertilizer treatments (no fertilizer, blood meal with 12% nitrogen at two rates: 100 and 200 lb per acre, and compost at 26 tons per acre) affected hemp yield and quality over two growing seasons (2019-2020).
