5.1.2 Sowing for textile applications

The main difference with sowing for technical applications is that a higher seeding density is applied for textiles: 70 - 75 kg/ha of seed;[1] about 400 seeds/m2. A denser sowing is needed for fine textile fibres. Besides that, other varieties are used (§3.3).
Findings from the Hemp4Textiles project (led by HOGENT) demonstrated that with a higher seeding density of 90 - 100 kg/ha (about 650 seeds/m2) a finer stem was obtained, however, fibres were not finer.[2] A similar result was observed in the HempSys project.[3]
