Tujuan penelitian untuk mengetahui pengaruh efektivitas biopriming terhadap benih cabai kadaluarsa. penelitian dilaksanakan di laboratorium ilmu dan benih, jurusan agroteknologi, fakultas pertanian, darussalam banda aceh. penelitian ini dilaksanakan dari bulan november 2024 sampai januari 2025. penelitian ini menggunkan rancangan acak lengkap (ral) pola non faktorial. faktor yang teliti adalah biopriming menggunakan rizobakteri 5 taraf yaitu r0 = kontrol (tanpa rizobakteri), r1 = at 7/1 t, r2= kl 8/4, r3 = ps 4/2, r4 = ps 5/6. setiap perlakuan diulang sebanyak 3 kali, sehingga diperoleh 15 unit percobaan, tiap satuan percobaan terdiri 25 benih cabai. jadi jumlah semua keselurahan benih sebanyak 375 benih. parameter yang diamati meliputi potensi tumbuh, daya berkecambah, indeks vigor, keserempakkan tumbuh, kecepatan tumbuh, waktu yang dibutuhkan untuk mencapai 50% kecambah total, tinggi tanaman umur 15, 30, dan 45 hss, jumlah daun umur 15, 30, dan 45 hss, bobot basah, dan bobot kering. hasil penelitian menunjukkan bahwa perlakuan biopriming rizobakteri pada benih cabai kadaluarsa berpengaruh sangat nyata terhadap peubah potensi tumbuh maksimum, daya berkecambah, kecepatan tumbuh, waktu mencapai 50% kecambah normal, dan bobot kering. berpengaruh nyata terhadap peubah indeks vigor, keserempakan tumbuh, bobot basah, dan tinggi bibit umur 15, 30, dan 45 hss. namun, berpengaruh tidak nyata terhadap jumlah daun umur 15, 30, dan 45 hss. perlakuan rizobakteri terbaik yaitu ps 4/2 unggul pada peubah potensi tumbuh maksimum, daya berkecambah, indeks vigor, keserempakan tumbuh, kecepatan tumbuh, waktu mencapai 50% kecambah normal, bobot basah, bobot kering, dan tinggi bibit umur 15, 30, dan 45 hss.

The objective of this study was to determine the effect of biopriming on expired chili seeds. The study was conducted at the Science and Seed Laboratory, Department of Agrotechnology, Faculty of Agriculture, Darussalam Banda Aceh. The study was conducted from November 2024 to January 2025. This study used a Complete Randomized Design (CRD) with a non-factorial pattern. The factors studied were biopriming using rhizobacteria at five levels: R0 = Control (without rhizobacteria), R1 = AT 7/1 T, R2 = Kl 8/4, R3 = PS 4/2, R4 = PS 5/6. Each treatment was repeated three times, resulting in 15 experimental units, with each unit consisting of 25 chili seeds. Thus, the total number of seeds was 375. The parameters observed included growth potential, germination rate, vigor index, growth uniformity, growth rate, time required to reach 50% total germination, plant height at 15, 30, and 45 days after sowing (DAS), number of leaves at 15, 30, and 45 DAS, fresh weight, and dry weight. The results of the study showed that the treatment of biopriming with rhizobacteria on expired chili seeds had a very significant effect on the variables of maximum growth potential, germination rate, growth rate, time to reach 50% normal germination, and dry weight. It had a significant effect on the variables of vigor index, uniformity of growth, fresh weight, and seedling height at 15, 30, and 45 HSS. However, it had no significant effect on the number of leaves at 15, 30, and 45 HSS. The best rhizobacterium treatment, PS 4/2, outperformed others in terms of maximum growth potential, germination rate, vigor index, growth uniformity, growth rate, time to reach 50% normal germination, fresh weight, dry weight, and seedling height at 15, 30, and 45 HSS
