Respons Bibit Bud Set terhadap Kombinasi Media Tanam dan Varietas Tanaman Tebu

Abstract

Pembibitan bud set merupakan metode single bud planting (SBP) yang keberhasilannya dipengaruhi oleh media tanam dan varietas. Penelitian ini bertujuan menganalisis pengaruh kombinasi media tanam dan varietas terhadap pertumbuhan vegetatif bibit bud set serta menentukan kombinasi terbaik. Penelitian menggunakan rancangan kelompok lengkap teracak (RKLT) faktorial dengan enam komposisi media tanam dan dua varietas tebu, yaitu BL dan PSNX 052. Parameter yang diamati meliputi tinggi batang, jumlah daun, diameter batang, panjang akar, bobot basah, curah hujan, pH media, dan sifat kimia media tanam. Data dianalisis menggunakan ANOVA dan uji DMRT taraf 5%. Hasil penelitian menunjukkan bahwa kombinasi media tanam dan varietas berpengaruh nyata terhadap pertumbuhan vegetatif bibit bud set. Kombinasi tanah 25%, blotong 50%, dan abu ketel 25% pada varietas PSNX 052 (M2V2) memberikan pertumbuhan terbaik, sedangkan varietas BL terbaik pada media blotong 100% (M5V1).

Bud set is a single bud planting (SBP) method whose success is influenced by planting media and variety. This study evaluated the effects of planting media combinations and sugarcane varieties on vegetative growth and identified the best treatment combination. The experiment was arranged in a factorial randomized complete block design (RCBD) consisting of six planting media compositions and two sugarcane varieties, BL and PSNX 052. The observed parameters included stem height, number of leaves, stem diameter, root length, fresh weight, rainfall, planting media pH, and the chemical properties of the planting media. 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 the interaction between planting media composition and sugarcane variety significantly affected the vegetative growth of bud set seedlings. The combination of 25% soil, 50% filter cake, and 25% boiler ash with PSNX 052 (M2V2) produced the best growth, while the BL variety performed best in 100% filter cake (M5V1).
