Moisture deficiencies occurring early in the crop cycle
may delay the maturity season and reduce yields.
Shortages later in the season often lower quality, as
well as yields. However, irrigation surplus, especially
late in the season, can reduce both the quality and the
post-harvest life of the crop.
Uneven or surplus irrigation, above the amount
required to replace evapotranspiration, causes nitrate
leaching below the root system and the ability of
the crop to recover from the nitrogen deficiency
decreases.
Efficient water use, namely irrigation scheduling, high
