Abstract

Penelitian ini bertujuan untuk mengetahui dan mempelajari pengaruh kombinasi pupuk NPK dan Vitamin B1 terhadap pertumbuhan bibit durian hasil sambung pucuk. serta mendapatkan kombinasi yang menghasilkan pertumbuhan terbaik. Penelitian ini dilaksanakan di Teaching and research farm Fakultas Pertanian Universitas Jambi, menggunakan Rancangan Acak Kelompok (RAK) satu faktor yang terdiri dari 6 perlakuan, yaitu 0 g pupuk NPK + 0 ppm Vitamin B1, 0 g Pupuk NPK + 750 ppm Vitamin B1, 15 g Pupuk NPK + 0 ppm Vitamin B1, 15 g Pupuk NPK + 750 ppm Vitamin B1, 30 g Pupuk NPK + 0 ppm Vitamin B1, dan 30 g Pupuk NPK + 750 ppm Vitamin B1. Hasil penelitian menunjukkan bahwa perlakuan kombinasi 15 g Pupuk NPK + 750 ppm Vitamin B1 memberikan hasil terbaik pada variabel pertambahan tinggi tanaman, pertambahan jumlah cabang primer, pertambahan jumlah cabang sekunder, panjang cabang sekunder, pertambahan jumlah daun, pertambahan luas daun, pertambahan diameter batang, bobot kering akar dan bobot kering tajuk. Namun demikian, tidak berpengaruh nyata terhadap variabel panjang cabang primer dan rasio tajuk akar. Perlakuan kombinasi 15 g pupuk NPK + 750 ppm Vitamin B1 dapat diaplikasikan dalam budidaya bibit durian di lapangan karena mampu mengoptimalkan pertumbuhan pada fase vegetatif. Kata kunci: Durian, pupuk NPK, Vitamin B1 This study aims to determine and examine the effects of the combination of NPK fertilizer and vitamin B1 on the growth of grafted durian seedlings, as well as to identify the combination that produces the best growth. The research was conducted at the Teaching and Research Farm, Faculty of Agriculture, Jambi University, using a one-factor Randomized Block Design (RBD) consisting of six treatments: 0 g NPK fertilizer + 0 ppm vitamin B1, 0 g NPK fertilizer + 750 ppm vitamin B1, 15 g NPK fertilizer + 0 ppm vitamin B1, 15 g NPK fertilizer + 750 ppm vitamin B1, 30 g NPK fertilizer + 0 ppm vitamin B1, and 30 g NPK fertilizer + 750 ppm vitamin B1. The results showed that the combination of 15 g NPK fertilizer + 750 ppm vitamin B1 gave the best results for plant height increment, number of primary branches increment, number of secondary branches increment, secondary branch length, number of leaves increment, leaf area increment, stem diameter increment, root dry weight, and shoot dry weight. However, it had no significant effect on primary branch length and shoot-root ratio. The combination of 15 g NPK fertilizer + 750 ppm vitamin B1 can be applied in the field cultivation of durian seedlings as it optimizes growth during the vegetative phase. Keywords: Durian, NPK fertilizer, Vitamin B1
