This research was conducted to compare drymatter production and yield pattern between commercial glasshouse (G) and plastic greenhouse (PG) in Korea. In both greenhouses sawing and plating of sweet pepper was 28 August and 27 September, 2007. Destructive measurement and yield of sweet pepper, cv. 'Derby', was obtained from January to May, 2008. Averaged light transmissivity over 20 times observed 65% in G and 51 % in PG. The averaged daily radiation sum of greenhouses during whole growing period was 9.03MJ/㎡/day for G and 7.37MJ/㎡/day for PG. Leaf area index (LAI) in G crop was 36% higher than the crop in PG at the end of experiment (247days after planting: DAP), whereas there was no significantly difference for 212 DAP in both greenhouses. Total dry matter production was 1759.9gㆍm-² for G and 1308.5gㆍm-² for PG. Fruit production observed 14.1kgㆍm-² in G and 7.8kgㆍm-² in PG. There was slightly difference measurement of dry matter distribution of generative or vegetative parts to total dry matter between G and PG.
