Abstract

Kembang kol (Brassica oleracea var. botrytis L.) merupakan sayuran ekonomis yang membutuhkan optimalisasi nutrisi organik dan agen hayati untuk meningkatkan hasil panen. Penelitian ini bertujuan untuk mengetahui dosis pupuk organik frass dan aplikasi Trichoderma sp. yang tepat terhadap pertumbuhan serta hasil kembang kol varietas PM 126 F1. Penelitian dilaksanakan di kebun percobaan Pertanian Universitas Sultan Ageng Tirtayasa pada Mei hingga September 2025. Metode penelitian menggunakan Rancangan Acak Kelompok (RAK) Fakultas Faktorial dengan dua faktor. Data dianalisis menggunakan Analysis of Variance (ANOVA) untuk mengetahui pengaruh nyata perlakuan. Hasil penelitian menunjukkan dosis pupuk frass berpengaruh nyata terhadap bobot segar tanaman, di mana dosis P3 (250 g) menghasilkan rata-rata tertinggi 219,78 g. Aplikasi Trichoderma sp. juga berpengaruh nyata terhadap hasil dengan bobot tertinggi pada perlakuan T3 (193,11 g). Tidak terdapat interaksi nyata antara kedua perlakuan, namun secara deskriptif kombinasi P3T3 menghasilkan bobot krop tertinggi mencapai 260,67 g.

Abstract

Objective: Soybean (Glycine max L. Merr.) is an important source of vegetable protein and a major food commodity. However, expanding soybean cultivation into dryland areas is constrained by drought stress, which adversely affects plant growth and productivity. This study aimed to evaluate the effects of biological fertilizers and drought stress on soybean growth and yield. Method: The experiment was conducted from October 2019 to January 2020 in a greenhouse using a factorial Randomized Block Design with three replications. The first factor was biological fertilizer application, consisting of no fertilizer, Plant Growth-Promoting Rhizobacteria (PGPR) at 10 g L⁻¹, and Arbuscular Mycorrhizal Fungi (AMF) at 10 g polybag⁻¹. The second factor was drought stress based on soil water availability (SWA): 100%–100%, 100%–50%, 50%–100%, and 50%–50% during vegetative and generative phases. Results: Biological fertilizers did not significantly affect soybean growth or yield. In contrast, drought stress significantly reduced plant height, leaf number, leaf area, root length, plant dry weight, pod number, seed number, and seed yield, with the greatest reductions occurring under 50% SWA during both growth phases. No significant interaction was observed between biological fertilizers and drought stress treatments. Novelty: Identify water availability as the primary determinant of soybean productivity under drought conditions, supporting sustainable food production and SDG 2 (Zero Hunger).
