|Abstract: ||The field experiment was conducted at the Indian Institute of Horticultural Research,
Hessaraghatta, Bangalore during 1999-2000 to study the “Response of grapes to microirrigation
under different evaporation replenishment rates”.
The fruit yield of grape was higher with drip irrigation (30.20 t ha-1) compared to
microjet irrigation (29.94 t ha-1). The yield attributing parameters like number of branches
per plant (90.75), average bunch weight (473.33 g), 100 berry weight (380.99 g), berry
diameter (22.23 cm2) and berry length (31.30 cm2) were higher with drip irrigation.
Increasing the evaporation replenishment increased the fruit yield and other yield
parameters like, the fruit yield was higher with 100 per cent evaporation replenishment
(31.98 t ha-1) which was on par with 75 per cent evaporation replenishment (31.53 t ha-1),
but it was lower with 50 per cent evaporation replenishment (26.69 t ha-1).
Evaporation replenishment rates did not influence the growth parameters like leaf area of
index leaf, fresh weight of index leaf, dry weight of index leaf, dry matter content of
index leaf and pruning weight although they were higher with 100 per cent evaporation
The total soluble solids was marginally higher with drip irrigation (15.43%)
compared to microjet irrigation (15.37%), but the titrable acidity did not vary with the
method of irrigation (0.34%). The sugar : acid was higher with drip irrigation (45.11)
compared to microject irrigation (44.86).
Irrigation scheduled with an evaporation replenishment rate of 75 per cent either
with microject or drip irrigation resulted in higher yields. The water use with 75 per cent
evaporation replenishment was 945.75 mm.|
