Pakcoy (Brassica chinensis L.) has the potential to be an alternative source of <br /> <br /> nutrition that is affordable for the community. This study was designed to determine <br /> <br /> the combination of vermicompost and water interval with the use of drip irrigation <br /> <br /> systems that can increase nitrogen uptake and chlorophyll content of pakcoy. The <br /> <br /> experiment was conducted using split-plot randomized block design with three <br /> <br /> replications. Watering interval as the main plot consists of three levels (once a day <br /> <br /> (V1), once every two days (V2), and once every three days (V3)). Growing media <br /> <br /> as subplots consisted of five levels with a ratio of soil and vermicompost 1: 0 (M0), <br /> <br /> 3: 1 (M1), 1: 1 (M2), 1: 3 (M3), 0: 1 (M4). The results showed that pakcoy plants <br /> <br /> grown in media with M2V3 treatment combination had the highest plant N content, <br /> <br /> which was 4.37%. The highest N uptake was obtained in the combination of M2V1 <br /> <br /> treatment with a value of N absorption of 183 mg / plant. The highest value of <br /> <br /> nitrogen use efficiency (NUE) was obtained in M2V1 treatment combination with <br /> <br /> a value of 18.4 g / g. The results of the variance analysis test showed that there was <br /> <br /> no interaction between growing media and water interval on the parameters of <br /> <br /> pakcoy chlorophyll content. The highest chlorophyll content was obtained by the <br /> <br /> combination of M3V3 treatment of 16.1 mg / L.
