| Abstract | Vegetable production in greenhouses is a necessary alternative to the current climatic conditions, and there are two types of greenhouses that are commonly used today: Greenhouse with a sawtooth and double roof. The objective of this research was to compare the suitability sawtooth and double roof houses for vegetable production. Both types of houses are structured in galvanized steel and anti-rust painted steel with dimensions (wxdxh) 6x24x5 m. Plastic roofing with a thickness of 200 microns covered with a plastic film that filters UV rays. The side is equipped with white net, size 32 mesh, all around. Inside the greenhouse, equipment and controls for drip irrigation and a 4-way fogger are installed. Automatic timer controls reduce the temperature and increase the relative humidity in the air during the day and record the environment during the day according to the crop production cycle. It was tested with cherry tomatoes and Hong Kong kale. The results showed that Cherry tomatoes grown in sawtooth tend to grow better than those grown on the double roof. But in terms of yield and yield composition, cherry tomatoes grown in the double roof were better than sawtooth. For Hong Kong kale grown in greenhouses, it was shown that the height and number of leaves on the last 7 days before plants, fertilized, non-significant, after 6 weeks of fertilization, it was shown that growth and yield of Hong Kong kale grown in greenhouses showed non-significant. |
