Abstract

The research aimedto testperformance ofa drip irrigationsystemto irrigate cauliflower cultivatedina greenhouse. The drip irrigationsystem using emitter type regulating stick emitter as many 315. One Mainpipe, 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 emissionuniformity (EU),water requirement,plant growth, andwaterproductivity. The resultsshowed that Emission uniformities were 64,49 % for gravitationalflow 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 7,20mm/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 was0,87 gram/litter. Keyword: cauliflower, cropwater requirement, drip irrigation, emitter, emission uniformity
