Abstract

Bawang merah (Allium ascalonicum L.) merupakan komoditas hortikultura yang potensial dikembangkan di Indonesia. Produksi bawang merah di Indonesia mengalami fluktuasi dan cenderung mengalami penurunan selama tiga tahun terakhir, sementara konsumsi bawang merah memiliki proyeksi tumbuh rata-rata 1,47% pertahun. Untuk memenuhi kebutuhan konsumsi bawang merah, petani cenderung menerapkan sistem pertanian intensif dengan input kimia tinggi yang berdampak pada penurunan kualitas tanah. Penelitian ini bertujuan untuk mengetahui pengaruh pupuk organik cair berteknologi nano dan abu ketel terhadap populasi bakteri pelarut fosfat, ketersediaan dan serapan fosfor, serta produksi bawang merah pada tanah Inseptisol Wajak. Penelitian dilaksanakan pada bulan November 2024 hingga Maret 2025 di greenhouse Fakultas Pertanian, Universitas Brawijaya, Kota Malang, Jawa Timur. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 6 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan bahwa perlakuan pupuk organik cair berteknologi nano dan abu ketel murni (P2) menghasilkan populasi bakteri pelarut fosfat tertinggi sebesar 2,16 x 105 CFU/g tanah. Perlakuan pupuk anorganik, pupuk organik cair berteknologi nano, dan abu ketel murni (P5) menghasilkan ketersediaan fosfor tertinggi sebesar 11,68 ppm. Perlakuan pupuk organik cair berteknologi nano dan abu ketel murni (P2) menghasilkan serapan fosfor tertinggi sebesar 0,12 g/tanaman. Perlakuan pupuk organik cair berteknologi nano dan abu ketel murni (P2) menghasilkan produksi bawang merah tertinggi yakni rata-rata jumlah umbi sebesar 23,75 buah/tanaman dan bobot kering umbi sebesar 11,8 g/tanaman.

Abstract

Earthworms play a crucial role in improving the biophysical quality of soil by enhancing aeration, porosity, and nutrient availability. However, their population is highly influenced by soil depth and the type of shade plant. This study aimed to explore the relationship between fine root development, earthworm density, and soil physical properties under different shade types in the coffee plantation of PTPN 1 Bangelan, which has experienced productivity decline due to poor soil conditions. The research was conducted from September 2024 to February 2025 across five coffee land blocks with varying shade types (sengon, lamtoro, jabon, clove, and no shade), using a Randomized Complete Block Design (RCBD) with three replications. Soil samples were collected at two depths (0–30 cm and 30–60 cm). The results indicated that shade type significantly affected earthworm density, fine root growth, and soil physical properties. Lamtoro provided the best results, increasing earthworm density by 27,5% (0–30 cm) and 20,51% (30–60 cm), along with a significant increase in total root length and specific root length. Earthworm density also showed a positive contribution to improved soil physical properties, including increased porosity (6,24%), total root length (53,64%), and specific root length (18,09%), as well as reduced bulk density (7,54%) and soil penetration resistance (24,37%). These findings highlight the importance of selecting appropriate shade plants—particularly lamtoro—to support sustainable coffee land management by enhancing soil biophysical quality.
