| description | An experiment on regulated deficit irrigation (RDI) strategies
was performed during 2004 in an orchard of ‘Clementina de
Nules’/’Citrange carrizo’ In Valencia Spain. Three different
irrigation scheduling protocols were compared. Two
approaches were based on the information derived from the
plant and a third one managed on a sustained, fixed deficit
application. Deficit irrigated treatments were compared
to a well-watered control treatment, irrigated at 100% of a
weighting lysimeter evapotranspiration (ETlis) located in
the same orchard. Water restrictions were applied during
the fruit growth period after June fruit drop, from July to
October, and during the rest of the year all treatments were
irrigated at 100% ETlis. Irrigation management based on
plant measurements consisted of a variable application rate
in order to maintain the maximum daily stem contraction
close to 125% and 135% of MDS value of control treatment
(MDS ratio management). Finally, the third deficit irrigation
treatment was irrigated at 52% of ETlis during the whole
restriction period. The results show that was possible to
schedule irrigation based on MDS information in order to
maintain the MDS ratio respect to the control around the
preset values of 125% and 135% respectively. Yield and
number of fruit per tree was significantly lower (p <0,05)
respect to control the RDfixed and MCD1,35, but not in the
MCD1,25 treatments. Fruit size distribution and fruit quality
in all treatment did not differ significantly (p <0,05) respect
to control, despite the water saving achieved, which ranged
from 12 to 19%, on an seasonal basis. |
