    Growing tomatoes with Basil does not appear to enhance tomato flavour but studies have shown that growing them around 10 inches apart can increase the yield of tomatoes by about 20%. [75] One study shows that growing chili peppers near tomatoes in greenhouses increases tomato whitefly on the tomatoes. [57]

  4. Irrigation - Wikipedia

    en.wikipedia.org/wiki/Irrigation

    In sprinkler irrigation, water is piped to one or more central locations within the field and distributed by overhead high-pressure water devices. Micro-irrigation is a system that distributes water under low pressure through a piped network and applies it as a small discharge to each plant. Micro-irrigation uses less pressure and water flow ...

    Case 1 is an empty tank at the charging pressure P c (gauge). The total volume of the tank is V t. Case 2 is a tank in use, with the air pressure at pressure P (gauge) and a water volume of V. Referring to the diagram on the right, a pressure tank is generally pressurized when empty with a "charging pressure" P c, which is usually about 2 psi ...

    The definition of a w is where p is the partial water vapor pressure in equilibrium with the solution, and p* is the (partial) vapor pressure of pure water at the same temperature. An alternate definition can be a w ≡ l w x w {\displaystyle a_{w}\equiv l_{w}x_{w}} where l w is the activity coefficient of water and x w is the mole fraction of ...

    Principle of a gas booster pump used to increase pressure of a compressed air supply. Gas pressure boosting may be used to fill storage cylinders to a higher pressure than the available gas supply, or to provide production gas at pressure higher than line pressure. Examples include:

    The biggest advantage of top-fed deep water culture over standard deep water culture is increased growth during the first few weeks. [citation needed] With deep water culture, there is a time when the roots have not reached the water yet. With top-fed deep water culture, the roots get easy access to water from the beginning and will grow to the ...

    Therefore, nitrogen is often the limiting factor for growth and biomass production in all environments where there is a suitable climate and availability of water to support life. Microorganisms have a central role in almost all aspects of nitrogen availability, and therefore for life support on earth.
