Kajian Kinerja Irigasi Tetes Pada Tanah Latosol dengan Budidaya Tanaman Caisim (Brassica Juncea L.)

Abstract

HOTLIN DERMAWATI APRIANI : Drip Irrigation Performance Analysis In Soil Cultivation Latosol With Caisim (Brassica juncea L.), supervised by SUMONO and SULASTRI PANGGABEAN. This study was conducted to determine the performance of drip irrigation on soil with vegetation Latosol Caisim plants (Brassica juncea L.) and without vegetation. Parameters measured were soil physical properties, evapotranspiration, field capacity, the average water flow output, uniformity of water use, drip irrigation efficiency, adequacy of irrigation water, and the dry weight of plants Caisim (Brassica juncea L.) The result showed that the largest water discharge emmiter 1 to 11 laterally at 8,87 l / h and the lowest at 9 lateral emmiter to 2 of 0,96 l / h and average discharge output of 5,57 l / h, the greatest uniformity occurs in the Lateral 1 by 66,27% and the smallest at the Lateral 2 was 12,64% with an average of 29,46%, the value of irrigation use efficiency at the end of the growth phase plants is high ie 100% in soil with plants or without plants. Irrigation storage efficiency value at the end of the growth phase of the plant is low in the soil with the plant 49,28% and without plants is 15,42%.
