In tomatoes, increases in fruit yield are typically the results of increased fruit size. [8] Research has shown that possible mechanisms for increased yield are likely due to increased water and nutrient uptake among vigorous rootstock genotypes. Conductance through the stoma was improved in tomato plants when grafted onto vigorous rootstock. [7]
In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Innovations, such as the use of fertilizer , the creation of better farming tools, new methods of farming and improved crop varieties , have ...
Excess subsurface water fills the pores in soil and inhibits their growth by depriving roots of air, resulting in root rot and plant death. An additional reason for sub-surface drainage is to ensure sufficient soil firmness for tillage and other access by heavy machinery to tend and harvest a crop.
Vapour pressure-deficit, or VPD, is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. Once air becomes saturated, water will condense to form clouds, dew or films of water over leaves. It is this last instance that makes VPD important for greenhouse regulation. If a ...
Reducing tillage may also improve soil structure and reduce the potential for soil erosion. Plants need a large number of nutrients in various quantities to flourish. Supplying enough nitrogen and particularly synchronization, so that plants get enough nitrogen at the time when they need it most, is a challenge for organic farmers. [ 55 ]

In practice, vertical farms employ advanced techniques such as hydroponics or aeroponics, allowing plants to grow without soil by using nutrient-rich water or air instead. By utilizing vertical space, these farms achieve higher crop yields per square foot compared to conventional farming methods.
