      Abstract
      Bawang merah merupakan salah satu komoditas pangan utama dan strategis yang produksi dan produktivitasnya sering tidak stabil. Salah satu upaya meningkatkan produktivitas bawang merah (Allium cepa L.) dengan memperbaiki kualitas kesuburan tanah dengan menambahkan pembenah tanah. Tujuan penelitian ini mengetahui pengaruh aplikasi bahan pembenah tanah ZeomicAgro dan Zeagro terhadap sifat kimia tanah, pertumbuhan, dan produksi tanaman bawang merah (Allium cepa L.). Penelitian dilakukan menggunakan rancangan acak kelompok (RAK) dengan empat perlakuan dan tiga ulangan. Perlakuan meliputi K0 = kontrol; ST (standar) = ZA 300 kg/ha, KCl 200 kg/ha, Urea 200 kg/ha, SP-36 200 kg/ha; P1 = Zeagro 200 kg/ha, ZA 200 kg/ha, KCl 150 kg/ha, Urea 150 kg/ha, SP-36 150 kg/ha; P2 = ZeomicAgro 200 kg/ha, ZA 200 kg/ha, KCl 150 kg/ha, Urea 150 kg/ha, SP-36 150 kg/ha. Zeagro merupakan pembenah tanah yang terbuat dari zeolit dan kapur sedangkan ZeomicAgro terbuat dari zeolit, kapur, dan bahan humat. Analisis sifat kimia tanah dilakukan pada tanah awal dan setelah panen pada 12 minggu setelah tanam (MST). Hasil analisis tanah menunjukkan bahwa pada perlakuan ZeomicAgro (P2) nyata meningkatkan N-total dan kejenuhan basa (KB), serta cenderung meningkatkan C-organik, P-tersedia, basa-basa dapat dipertukarkan, dan KTK dibandingkan standar dan perlakuan Zeagro. Perlakuan ZeomicAgro (P2) nyata meningkatkan tinggi tanaman, bobot basah, bobot kering, dan produktivitas dibandingkan standar dan Zeagro. Produktivitas tertinggi dicapai pada 6.79 ton/ha. Perlakuan ZeomicAgro dapat mengefisienkan penggunaan pupuk Urea, KCl, dan SP-36 hingga 25% dan pupuk ZA hingga 30% dari dosis standar.
       
      Shallots are one of the main and strategic food commodities whose production and productivity are often unstable. One of the efforts to increase the productivity of shallots (Allium cepa L.) by improving the quality of soil fertility by adding soil ameliorant. The purpose of this study is to determine the influence of the application of ZeomicAgro and Zeagro soil ameliorant agents on soil chemistry, growth, and production of shallot plants (Allium cepa L.). The research was conducted using a group random design (RAK) with four treatments and three repetitions. Treatment includes K0 = control; ST (standard) = ZA 300 kg/ha, KCl 200 kg/ha, Urea 200 kg/ha, SP-36 200 kg/ha; P1 = Zeagro 200 kg/ha, ZA 200 kg/ha, KCl 150 kg/ha, Urea 150 kg/ha, SP-36 150 kg/ha; P2 = ZeomicAgro 200 kg/ha, ZA 200 kg/ha, KCl 150 kg/ha, Urea 150 kg/ha, SP-36 150 kg/ha. Zeagro is a soil ameliorant made of zeolite and lime while ZeomicAgro is made of zeolite, lime, and humic acid. Analysis of soil chemical properties was carried out on the initial soil and after harvest at 12 week after planting. The results of soil analysis showed that in the ZeomicAgro (P2) treatment, it significantly increased total nitrogen and base saturation, tended to increase organic carbon, available phosphorus, exchangeable bases, and cation exchange capacity (CEC) compared to standard and Zeagro treatment. ZeomicAgro (P2) treatment significantly increased crop height, wet weight, dry weight, and productivity compered to standard and Zeagro treatment. The highest productivity was achieved at 6.79 tons/ha. ZeomicAgro treatment can increase the use of Urea, potassium chloride (KCl), and super phosphate-36 (SP-36) fertilizers up to 25% and fertilizer zwavelzure amonium (ZA) up to 30% of the standard dose.
