Abstract

The fluctuating and decreasing production of shallots impacts the national stock. Its cultivation using high inorganic fertilizers requires high costs, reduces soil fertility, and affects long-term production.  Efforts are needed to increase production at a lower cost, reduce the use of inorganic fertilizers, and be more environmentally friendly.  One of them is using eco-enzymes that can be used as fertilizers, soil conditioners, and as a source of plant nutrients.  This study aims to evaluate and analyze the effectiveness and potential of eco-enzymes to increase the growth and production of shallots, while reducing the amount of inorganic fertilizer.  The study used a Randomized Block Design, four replications. There were three levels of treatment: P1 eco-enzyme; P2 eco-enzyme + N, P, K fertilizer 50%; P3 N, P, K fertilizer 100%. Each treatment consisted of 8 experimental units, for a total of 96, with a dose of N= 150 kg urea.ha-1, P= 200 kg SP-36.ha-1 and K= 150 kg KCl.ha-1. Eco-enzyme was given every week with a concentration of 1 ml.l-1; half was given by spraying the plants and half by watering the media.  The results showed that eco-enzyme is effective and can potentially increase the growth and production of shallots and reduce the use of inorganic fertilizers N, P, and K by up to 50%. The eco-enzyme + 50% N, P, K fertilizer produced shallot with the highest number of leaves per bulb and clump, number of bulbs per clump, circumference of bulbs, weight per bulb, and weight of bulbs per clump.

Abstract

Pertanian perkotaan merupakan solusi strategis untuk memenuhi kebutuhan pangan masyarakat, khususnya dalam budidaya hortikultura. Salah satu komoditas sayuran yang permintaannya terus meningkat adalah kailan (Brassica oleracea L.). Namun, budidaya di perkotaan menghadapi tantangan dalam hal penyiraman yang sering kali kurang efisien jika dilakukan secara manual. Oleh karena itu, diperlukan sistem pengairan yang lebih efektif, seperti irigasi kapiler dan irigasi tetes. Keberhasilan budidaya juga sangat ditentukan oleh kecukupan air dan nutrisi yang tersedia. Pemanfaatan bahan organik seperti asam humat dapat membantu meningkatkan kualitas dan kuantitas hasil panen karena kemampuannya memperbaiki struktur media tanam, meningkatkan kemampuan menahan air, serta memfasilitasi penyerapan unsur hara oleh tanaman. Penelitian dilakukan di Kebun Percobaan Fakultas Pertanian Universitas IBA yang berada di Palembang, pada bulan April - Mei 2025, menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor perlakuan. Faktor pertama adalah sistem pengairan (S0: penyiraman biasa, S1: irigasi kapiler, S2: irigasi tetes), dan faktor kedua adalah dosis asam humat (H0: 0 g.l-1, H1: 1.5 g.l-1, H2: 3 g.l-1, H3: 4.5 g.l-1). Hasil penelitian menunjukkan interaksi perlakuan berpengaruh signifikan terhadap bobot panen dan bobot kering tanaman. Perlakuan sistem pengairan berpengaruh signifikan terhadap tinggi tanaman, jumlah daun, luas daun, dan bobot panen, sedangkan perlakuan asam humat berpengaruh signifikan terhadap seluruh parameter pertumbuhan. Kesimpulannya, kombinasi irigasi kapiler dan asam humat 3 g.l-1 memberikan hasil optimal untuk produksi kailan di lingkungan perkotaan.
