ANALISIS EFISIENSI IRIGASI TETES DAN KEBUTUHAN AIR TANAMAN SAWI (Brassica juncea) PADA TANAH INCEPTISOL
ABSTRACT: Nowadays, the
increasing human need
for water, is
in sharp contrast
with the increasingly
limited water availability, especially in agriculture so that
adversely affect the
crop production. Therefore
it is necessary
to use the availability of water effectively and efficiently by
creating an appropriate irrigation technologies and efficient in water as drip
irrigation. This study was aimed to analyze the efficiency of drip irrigation
and crop water requirements of mustard using inceptisol soil. The measurements
were made by direct observation in the
field at three growth phases, namely the initial, middle, and late phases. The
results showed that the crop water requirements of mustard in the early phase
was 2.88 mm.day-1, in the middle
phase was 6.58
mm.day-1 and in
the late phase
of growth was
6.1 mm.day-1. Efficiency
consumption produced was very
high with average
of 100% and
storage efficiency was
low i.e <
90%. This indicated
an imbalance between water usage
efficiency and storage, so that the production of mustard plant that produced
was not optimal.
Key words: efficiency, drip
irrigation, inceptisol soil, crop water requirement, mustard
