ECONOMIC RETURNS OF IRRIGATION SYSTEMS FOR THE MOST IMPORTANT CROPS IN NEW LANDS IN BENI SUEF GOVERNORATE

Document Type : Research articles.

Abstract

This study aims to determine the most appropriate irrigation systems
that achieve higher economic efficiency in the production of the most
important crops in Beni Suef, determines the potential for horizontal
expansion in Beni Suef according to water resources available and under use
of modern irrigation systems. The main findings are summarized as
following: Changes in productivity, amount of irrigation water, cultivated
area, and the production & economic efficiency of the unit of irrigation water
are reported as follow. As for tomatoes, productivity has increased by 9.3 tons
in case of drip irrigation which represent an increase of 51.38% compared to
productivity in flood irrigation. As for onion, productivity has increased by 6.9
tons in case of drip irrigation which represent an increase of 49.3% compared
to productivity in flood irrigation. As for pepper, productivity has increased by
2.9 tons in case of drip irrigation which represent an increase of 19.5%
compared to productivity in flood irrigation. As for wheat, productivity has
increased by 2.5 and 0.95 bushels in case of drip irrigation and sprinkle
irrigation respectively, which represent an increase of 16.7% and 6.5%
compared to productivity in flood irrigation. The drip irrigation system in
tomatoes is proved to reduce water consumption per feddan of tomato of about
454 cubic meters compared to flood irrigation. Change flood irrigation system
into dripping system may save about 5.22 million cubic meters for Beni Suef
and about 141.6 million cubic meters for Egypt. The preserved amount of
water can be used to expand the area cultivated with tomatoes by about 2.2,
59.5 thousand feddans for Beni Suef and Egypt respectively. The drip irrigation system in onion is proved to reduce water consumption per feddan
of tomato of about 450 cubic meters compared to flood irrigation. Change
flood irrigation system into dripping system may save about 3.3 million cubic
meters for Beni Suef and about 22 million cubic meters for Egypt. The
preserved amount of water can be used to expand the area cultivated with
onion by about 2 and 13.4 thousand feddans for Beni Suef and Egypt
respectively considering that the water requirements per feddan of onion is
1650 cubic meters.The drip irrigation system in pepper is proved to reduce
water consumption per feddan of tomato of about 542 cubic meters compared
to flood irrigation. Change flood irrigation system into dripping system may
save about 1.95 million cubic meters for Beni Suef and about 40.5 million
cubic meters for Egypt. The preserved amount of water can be used to expand
the area cultivated with onion by about 0.72 and 15 thousand feddans for Beni
Suef and Egypt respectively. As for wheat, the drip irrigation system in wheat
is proved to reduce water consumption per feddan of tomato of about 470
cubic meters compared to flood irrigation. Change flood irrigation system into
dripping system may save about 4.4 million cubic meters for Beni Suef and
about 292.3 million cubic meters for Egypt. The preserved amount of water
can be used to expand the area cultivated with onion by about 2.5 and 166
thousand feddans for Beni Suef and Egypt respectively. The sprinkle irrigation
system in wheat is proved to reduce water consumption per feddan of tomato
of about 250 cubic meters compared to flood irrigation. Change flood
irrigation system into dripping system may save about 4.3 million cubic
meters for Beni Suef and about 155.5 million cubic meters for Egypt. The
preserved amount of water can be used to expand the area cultivated with
onion by about 1.2 and 78.5 thousand feddans for Beni Suef and Egypt
respectively.
