Effect of Greenhouse Light Transmissivity and Plant Density on Cucumber Production

Background In a greenhouse, a favorable climate is realized to have sunlight converted to fresh vegetable crops. In general, the more light a crop receives, the more product can be grown. Then, additional light will hardly lead to additional production and ...

Improving Yield of Sweet Pepper in Med-Tech Greenhouses

Background Sweet pepper is one of the most important greenhouse vegetable crops grown in the Kingdom of Saudi Arabia. The average production of sweet pepper in Med-Tech greenhouses ranged from 12-15 kg/m2, which is considered less than the poten...

Pepper Production in Closed Hi-Tech Greenhouse

Background Bell pepper is a valuable greenhouse crop that might have large benefits from being grown in a well-controlled air-conditioned greenhouse. Estidamah has four such greenhouse compartments. In 2017, the first experiment was carried out to get some benchmarks and ...

Introducing Date Palm Waste as potential local soilless culture substrate in comparison to Rockwool, Coco-peat and Perlite - Tomato

Background Rockwool is one of the most commercially used substrates in soilless cultivation that usually imported, with high cost. Furthermore, Rockwool is an inorganic material that has no proper waste processing by the end of the growing season. ...

Effect of Diffuse Glass greenhouse cover compared to Clear Glass cover on Cucumber Production

Background Based on positive effects reported on using diffuse covering materials in a number of studies in the Netherlands, it can be expected that diffusive cover gives much better harvests than a cover with clear glass in sunny zones i.e....

Grafting of Tomato

Background Grafting is a well-known technique that enables to combine the best of two worlds in tomato production. In grafting, a strong and resilient rootstock to support the water and nutrient uptake and a scion (the top part) that promises to give the wanted growth a...

Effect of Plant Stem Density on Tomato Yield

Background In the greenhouse, the solar light is converted to a marketable vegetable product. For this, the plants will have to intercept the solar light, and the more plants, the more light will be intercepted. But, standing next to each other, the plants also compete f...

Evaluation of Biological Control of Key Tomato Pests in Greenhouses Status Completed Project Year 2020 Research Theme Integrated Pest Management

Background Tomatoes are susceptible to a wide range of Insect and Arachnid pests that could damage the plant, reduce production, and fruit quality, and sometimes result in total yield loss. In Saudi Arabia, most of tomato growers use chemical pesticides for plant prot...

Sweet Pepper Yield and Water Use Efficiency as Affected by Local and Imported Soilless Substrates

Background Soilless culture is considered an important and valuable technique to grow vegetable crops in the Kingdom of Saudi Arabia in order to reduce the risk of root-borne diseases and have the possibility of saving water and nutrients. Furthermore, cost of substrat...
