Abstract: | Katuk (Sauropus androgynus L.) merupakan salah satu jenis sayuran indigenous di Indonesia yang
dapat memenuhi kebutuhan nutrisi manusia dan digunakan sebagai obat-obatan herbal. Tanaman yang
mengalami cekaman air memerlukan tambahan unsur hara dalam mendukung proses pertumbuhan, salah satunya dengan cara pemupukan. Penelitian bertujuan mengetahui pengaruh cekaman air dan interval pemupukan daun terhadap pertumbuhan tanaman katuk. Rancangan percobaan yang digunakan adalah rancangan split-plot dalam rancangan kelompok lengkap teracak (RKLT) yang terdiri atas 2 faktor yaitu interval pemupukan daun sebagai petak utama dan cekaman air sebagai anak petak. Interval pemupukan daun terdiri dari 3 taraf, yaitu P0 (tanpa pemupukan), P1 (2 minggu sekali), dan P2 (4 minggu sekali) . Faktor cekaman air terdiri dari 4 taraf, yaitu C1 (40% kapasitas lapang (KL)), C2 (60% KL), C3 (80% KL ), dan C4 (100% KL). Penelitian dilakukan dengan 3 ulangan yang diperoleh dari 12 kombinasi, sehingga
terdapat 36 satuan percobaan. Cekaman air tidak berpengaruh nyata terhadap pertumbuhan tanaman katuk. Waktu pemupukan daun berpengaruh nyata terhadap parameter jumlah cabang, jumlah daun, dan bobot panen dengan interval 2 minggu sekali. Waktu pemberian pemupukan optimal Interaksi antara cekaman air dan pemupukan daun tidak berpengaruh terhadap pertumbuhan tanaman katuk. Katuk (Sauropus androgynus L.) is one of the indigenous vegetables in Indonesia that can meet human nutritional needs and is used as herbal medicine. Plants experiencing water stress require additional nutrients to support the growth process, one of which is fertilization. The study aimed to determine the effect of water stress and foliar fertilization interval on the growth of katuk plants. The experimental design used was a split-plot design in a completely randomized group design (RKLT) consisting of 2 factors: leaf fertilization interval as the main plot and water stress as a subplot. The foliar fertilization interval consisted of 3 levels, namely P0 (without fertilization), P1 (2 weeks), and P2 (4 weeks). The water stress factor consists of 4 levels, namely C1 (40% field capacity (KL)), C2 (60% KL), C3 (80% KL), and C4 (100% KL). The study was conducted with three replications obtained from 12 combinations so that there were 36 experimental units. Water stress did not significantly affect the growth of katuk plants. The time of foliar fertilization had a significant effect on the parameters of the number of branches, number of leaves, and harvest weight at intervals of 2 weeks. Optimal fertilization time The interaction between water stress and foliar fertilization did not affect the growth of katuk plants. |
