Efisiensi Irigasi Tetes Dan Kebutuhan Air Tanaman Bunga Kol Pada Tanah Andosol

Abstract

IRVAN IMMANUEL SILALAHI :The Efficiency of Drip Irrigation and Plant Water Requirement of Cauliflower on Andosol Land, supervised by SUMONO and SAIPUL BAHRI DAULAY. This research was held to determine and assess the efficiency of drip irrigation and crop water requirement of cauliflower on andosol land. The parameters observed were the efficiency of the use of water, the efficiency of the water storage and plant water requirement. The results of this experiment indicated thatthe lowest water consumption efficiency was occur seed in the early phase of growth was 91,85%, the largest water consumption efficiency was occured in the beginning, middle and end phase of the growth was 100%. The lowest water storage efficiency occured was at the early phase of growth was 23,77%, the largest water storage efficiency occured was in the final phase was 76,42%. Crop water requirement in the initial phase was 2.88 mm/day, in the middle phase of growth was 6,58 mm/day and the final phase of the growth was 6.1 mm/day
