ANALISIS EFISIENSI IRIGASI TETES DAN KEBUTUHAN AIR TANAMAN SEMANGKA (Citrullus vulgaris S.) PADA TANAH ULTISOL
ABSTRACT: This research
was held to
analysis the efficiency
of drip irrigation
and crop water
requirement of watermelon
on ultisol soil. The
parameters observed were
water discharge, crop
water requirement, physical
properties of the
soil, and the efficiency of drip irrigation (water
usage and water storage). The results of this experiment indicated that the
average value of water discharge was 898.4 ml.hour-1. The highest crop water
requirement in the middle phase of growth was 6.23 mm.day-1 and the lowest crop
water requirement occurred in the early phase of growth was 2.80 mm.day-1.
Ultisol soil has sandy clay loam texture with a bulk density of 1.18 gr.cm-3, 2.12
gr.cm-3 particle density, and porosity of 43.20%. The largest water consumption
efficiency was 100% and the lowest water consumption efficiency was occurred in
the middle phase of growth i.e 96.7%. The largest water storage efficiency was
occurred in the middle phase i.e 89.13% and the lowest water storage efficiency
was occurred at the early phase of growth i.e 33.12%.
