Jagung merupakan tanaman pangan utama kedua setelah padi. Jagung Merah Sigi (Mesi) berasal dari Sigi, Sulawesi Tengah. Jagung Mesi memiliki penampilan yang menarik, rasa manis, dan aroma khas. Upaya memperoleh hasil optimal budidaya jagung Mesi adalah dengan pemberian Zat Pengatur Tumbuh (ZPT). ZPT berperan dalam merangsang maupun menghambat pertumbuhan tanaman. ZPT yang terkandung dalam Bioaktivator yaitu 5,029 mg L-1 Indole Acetic Acid, 9,819 mg L-1 Giberelin, 1,603 mg L-1 Zeatin dan 0,933 mg L-1 Kinetin. Kandungan ZPT dalam Booster yaitu senyawa asam laktat, asam amino, dan Lactobacillus. Tujuan penelitian untuk mengetahui daya hasil tanaman jagung Merah Sigi dengan pemberian beberapa ZPT. Penelitian dilaksanakan di Taman Teknologi Pertanian Bangun Rejo, Kabupaten Kutai Kartanegara, Kalimantan Timur dari April hingga Juli 2023. Penelitian menggunakan Rancangan Acak Kelompok non faktorial, terdiri atas 4 perlakuan yang diulang 8 kali, yaitu tanpa pemberian Bioaktivator dan Booster (kontrol), 7 mL L-1 Bioaktivator, 7 mL L-1 Booster, kombinasi antara 3,5 mL L-1 Bioaktivator dan 3,5 mL L-1 Booster. Data dianalisis dengan sidik ragam dan dilanjutkan dengan uji Beda Nyata Terkecil pada taraf 5%. Hasil penelitian menunjukkan perlakuan pemberian Bioaktivator, Booster dan kombinasinya berpengaruh tidak nyata pada semua parameter. Perlakuan 7 mL L-1 Booster menghasilkan rata-rata bobot 100 butir jagung sebesar 23,70 g, hanya mampu meningkatkan sebesar 4,64% dibandingkan dengan kontrol. Hasil bobot 100 butir jagung Merah Sigi masih sesuai dengan potensi bobot 100 butir jagung pada deskripsi yaitu 23,01 g. Kombinasi 3,5 mL L-1 Bioaktivator dan 3,5 mL L-1 Booster memberikan rata-rata berat pipilan kering per petak sebesar 1,18 kg.Downloads
