Abstract

Kecamatan Salimpaung merupakan daerah pertanian hortikultura dengan kondisi tanah Inceptisol hingga Andisol di ketinggian hingga 1000 mdpl. Komoditas utama seperti cabai merah dan bawang merah menjadi andalan, namun gejolak harga sering memengaruhi inflasi nasional. Cabai merah memiliki permintaan tinggi tetapi rentan penurunan produksi saat musim hujan, sementara bawang merah terus meningkat kebutuhannya seiring bertambahnya jumlah penduduk. Salah satu inovasi pendukung budidaya tanaman hortikultura adalah teknologi soil block, media semai cetak ramah lingkungan yang terbuat dari limbah organik seperti sedimentasi rawa, pupuk kandang, fosfat alam, dolomit, dan cocopeat. Teknologi ini mengurangi limbah plastik, lebih ekonomis, serta mempermudah pembibitan berbagai tanaman sayuran seperti cabai, bawang merah, dan tomat.  Kegiatan pengabdian masyarakat berupa bimbingan teknis pembuatan soil block dilakukan untuk meningkatkan pemahaman kelompok tani hortikultura di Kecamatan Salimpaung dalam menyiapkan media semai berkualitas. Soil block memberikan banyak keunggulan, seperti tidak mencemari lingkungan, mendukung pertumbuhan akar tanpa gangguan, menghemat tempat, waktu, dan biaya. Kesimpulan dari kegiatan ini menunjukkan bahwa teknologi soil block efektif meningkatkan kualitas persemaian tanaman hortikultura sekaligus berkontribusi pada keberlanjutan lingkungan. Direkomendasikan pelatihan lanjutan agar petani mampu secara mandiri memproduksi bibit hortikultura berkualitas dalam jumlah besar.

Abstract

These soils are subject to periodic flooding, leading to acidic conditions and low fertility. This study aimed to determine the role of dolomitic lime and Azolla sp. liquid organic fertilizer in enhancing corn yields on alluvial soils. The experiment utilized a completely randomized design (CRD) factorial with two factors. The first factor included three dolomite lime dosage levels: 0, 2, and 4 Mg ha−1. The second factor was levels of Azolla sp. liquid organic fertilizer: 0, 50, and 100 ml L−1. Each treatment was repeated three times, resulting in 27 experimental units. Data were analyzed using ANOVA with the F test, followed by the Least Significant Difference (LSD) test at a 5% significance level. Observations included soil pH, plant height, Leaf Area Index (LAI), weight of 100 kernels, corn dry yield, and liming and fertilization efficiency. The relationship between variables and yield is expressed as: Yield = -10.032 + 1.007 pH + 1.796 LAI + 0.17 weight of 100 kernels; R2 = 74.9%.  The highest corn yield was 7.35 Mg ha−1 with a liming efficiency of 30%. Applying 100 ml L−1 of Azolla sp. liquid fertilizer resulted in a yield of 7.23 Mg ha−1 with a fertilization efficiency of 28%.
