Ketersediaan air merupakan faktor penting dalam pertumbuhan bibit tebu budset (Saccharum officinarum L.) pada fase pembibitan. Penelitian ini bertujuan menganalisis pengaruh volume, frekuensi, dan interaksi penyiraman terhadap pertumbuhan bibit tebu varietas PSNX-052. Penelitian dilaksanakan di rumah pembibitan PG Rendeng menggunakan rancangan kelompok lengkap teracak (RKLT) faktorial dengan dua faktor, yaitu frekuensi penyiraman (1, 2, 3, dan 4 kali per hari) dan volume air (33, 100, dan 200 ml tanaman/aplikasi). Parameter yang diamati meliputi daya berkecambah, tinggi batang, diameter batang, jumlah daun, dan jumlah anakan. Data dianalisis menggunakan ANOVA dan dilanjutkan uji DMRT taraf 5%. Hasil penelitian menunjukkan bahwa volume dan frekuensi penyiraman tidak berpengaruh nyata terhadap daya berkecambah, tinggi batang, jumlah daun, dan jumlah anakan. Interaksi volume dan frekuensi penyiraman berpengaruh nyata terhadap diameter batang pada 5–10 minggu setelah tanam.

MUHAMMAD THARIQ RAMADHAN. The Effect of Irrigation Volume and Frequency on the Growth of Sugarcane (Saccharum officinarum L.) Seedlings. Supervised by MERRY GLORIA MELIALA.

Water availability is an important factor affecting the growth of sugarcane budset (Saccharum officinarum L.) seedlings during the nursery stage. This study aimed to evaluate the effects of irrigation volume, irrigation frequency, and their interaction on the growth of PSNX-052 sugarcane seedlings. The experiment was conducted at the PG Rendeng nursery using a factorial randomized complete block design (RCBD) with two factors: irrigation frequency (once, twice, three times, and four times daily) and irrigation volume (33, 100, and 200 ml plant/application). Observed parameters included germination percentage, plant height, stem diameter, number of leaves, and number of tillers. Data were analyzed using analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) at the 5% significance level. The results showed that irrigation volume and irrigation frequency had no significant effects on germination, plant height, number of leaves, or number of tillers. However, the interaction between irrigation volume and frequency significantly affected stem diameter at 5–10 weeks after planting.
