postharvest storage temperature and duration on quality of baby spinach in South Africa. Materials and methods Plant materials and storage conditions. ‘Ohio’ baby spinach (Hygrotech, Pretoria, South Africa) were grown from seed in a glasshouse with temperature
summer cooling. These changes greatly enhance the temperature control capacity of the greenhouse and provide larger spaces and overall better performance. It is beautiful and convenient for management to array many modern solar greenhouses together ( Fig
treated in a larger (90-L) recirculating water bath set to 25 °C as a room-temperature control treatment, and an additional three melons were kept untreated as a negative treatment control (total of 15 melons). After treatment, all melons were placed in a
Greenhouse Complex, Auburn University, Auburn, AL. Temperature controls in the greenhouse were set to maintain a temperature between 19 °C and 26 °C, and plants were grown under natural lighting. The trial was designed as a 2 × 5 factorial evaluating two
the production of vegetable crops is well established. Plastic mulches are used to increase soil temperature, control weeds, and consequently improve crop yields. Plastic mulches reduce nutrient leaching, and stabilize soil moisture ( Zajicek and

the previously mentioned cooling systems. Heat pumps can also be used in greenhouse cooling systems. Although they offer a wide range of temperature control, their efficiency is largely dependent on the pump’s power consumption and type of refrigerant
considerably. Among the main changes, the trailers are now longer (≈16 m), their walls are thinner to reduce weight, their refrigeration capacity has increased, their temperature control systems have improved, they have better air delivery chutes, and also more
fertilizer was added when the water volume decreased to ≈70% to 80% of the initial volume. Greenhouse experiments. Two greenhouse experiments were conducted in a temperature-controlled greenhouse that included six experimental treatments: 1) noninoculated
