APLIKASI SISTEM IRIGASI TETES PADA TANAMAN KEMBANG KOL (Brassica Oleracea Var. Botrytis L. Subvar. Cauliflora DC) DALAM GREENHOUSE
ABSTRACT: The research aimed
to test performance of a drip irrigation system to irrigate cauliflower
cultivated in a greenhouse. The drip irrigation system using emitter type
regulating stick emitter as many 315.
One Main pipe, one manifold, and four lateral pipes were from PE types
with the diameter of 13 mm. The methods
to deliver irrigation water were by using a small pump 13 Watt and by using
gravitational pressure with head 155 cm. Variables observed were emission
uniformity (EU), water requirement, plant growth, and water productivity. The results showed thatEmission uniformities
were 64,49 % for gravitational flow and 61,46 % for pumping flow. These values were still below recommended,
that is 75 % - 85 %. The minimum, maximum, and mean reference
evapotranspiration (ETo) were recorded as 5,80 mm/day, 9,70 mm/day, and 7,20
mm/day. Whilst crop evapotranspiration
(ETc) at the day of 41 after planted was 3.2 mm/day. Average yield of cauliflower was 58 gram per
plant, while water productivity was 0,87 gram/litter.
