The flower yield strongly depends on the number of harvests. Argentina usually produces approximately 2000 to 3000 kg/ha fresh product (400 to 500 kg not-cleaned dry product). In the former Soviet Union a yield of approximately 300 to 500 kg/ha at four harvests per year was achieved. In Egypt approximately 3152 kg/ha (fresh) were harvested, in Germany up to 800 kg drug/ha, and in India approximately 600 kg/ha.

The drying relation is approximately 1:5 to 6.5. According to Heeger [1] the yield of dry flowers is 500 to 2000 kg/ha, in general 500 to 1200 kg/ha, and the yield of the whole dry plant is 2000 to 5000 kg/ha, in general from 2000 to 3000 kg/ha.

In the years 1987 to 1996, the total harvest in Argentina amounted to more than 2000 tons of drug per year with a drop during the last years of the period. The greater part of the drug crop is exported, above all to Europe (Table 5.8.1).
