Abstract:

In Israel’s inner valleys banana irrigation under screens is reduced below rates for open stands by about 25% while in coastal regions reductions are about 10%. The ratio of evaporation inside to that outside decreases during the season due to changes in internal climate caused by accumulation of dust on the screen which reduces transmission of solar radiation and growth of the banana plants which reduces wind. We can exploit these changes to reduce irrigation by irrigating every day according to yesterday’s climate and recently completed a five year experiment which shows that irrigation can be reduced this way by another 15%.
