abstract = "A common problem of all fruit producers is establishing the optimal irrigation
schedule (irrigation interval and amount of water) which would provide a highquality yield with efficient use of water, preservation of soils and the environment.
In this study, Seasonal Irrigation Water Requirement (SIWR) was calculated from
the difference between the crop evapotranspiration (ETc) and effective rainfall (Pe)
for the fruit crops in the 13 districts of Central (CS), West (WS), and South Serbia
(SS). Analysed fruit production averaging around 9.8% of total arable land area.
Depending on the crop water requirements and grass cover (GC) fruits were
separated into seven groups: apples, pears, plums, walnuts and hazels without GC (I)
and with GC (II); apricots, peaches, nectarines without GC (III) and with GC (IV);
sweet cherries, sour cherries without GC (V) and with GC (VI) and raspberries,
blackberries, blueberries (VII). Reference evapotranspiration (ETo), Pe, ETc, and
SIWR were calculated based on FAO-56 methodolgy using daily meteorological
data (mean, maximum and minimum temperature ,extra-terrestrial radiation and
rainfall) for the period 2000-2019 obtained from 13 meteorological stations. The
average SIWR amounts to 349, 541, 153, 272, 123, 220, and 207 mm for all the
seven groups; I, II, III, IV, V, VI, and VII, respectively. Spatially SIWR values
ranged from 232.8, 366.5, 428.2 mm for WS, CS, and SS districts respectively.
Depending on whether the orchard is grass-covered or not ETo changes significantly.
Crop evapotranspiration is 26% higher in the GC orchards compared to the orchards
without GC. Great differences in SIWR going from Western to Eastern parts of
Serbia indicate that for good irrigation practices and efficient irrigation system
design, it is necessary to adopt SIWR calculated on a district scale or even farm scale.
Obtained results indicate that besides SIWR, selecting the proper agronomy practices
and growing systems has a significant impact on obtaining high-quality yields while
saving water and preserve soils.",
