Abstract

Pemupukan urea di petani umumnya dilakukan dengan dosis yang lebih tinggi dari standar pemerintah. Penggunaan pupuk urea berlebih dapat menurunkan produksi, kualitas tanaman, serta pencemaran lingkungan. Tujuan percobaan ini adalah melihat respon pertumbuhan, hasil dan kualitas padi sawah pada media N rendah. Rancangan percobaan menggunakan rancangan acak kelompok faktorial, dosis pupuk urea (0%, 40%, dan 100% 250 kg ha-1) dan varietas padi (Way Apo Buru dan Inpari 33). Parameter yang diamati adalah tinggi tanaman (cm), jumlah anakan, jumlah daun, chlorophyl fluorescence (unit), gabah isi (%), jumlah malai, kandungan protein terlarut (mg g-1), vitamin C (mg g-1), dan gula reduksi (mg g-1). Hasil penelitian menunjukkan bahwa reduksi pupuk urea 40% menghasilkan jumlah anakan yang sama tinggi dengan dosis standar (250 kg ha-1). Pemupukan urea dosis standar menghasilkan kandungan vitamin C, nilai chlorophyl fluorescence dan jumlah malai yang tertinggi. Inpari 33 menghasilkan karakter tinggi dan persentase gabah isi yang lebih baik sementara Way Apo Buru menghasilkan jumlah daun yang lebih tinggi. Reduksi 40% dosis urea pada Inpari 33 menghasilkan kandungan protein terlarut tertinggi. Inpari 33 menghasilkan gula reduksi terendah sehingga dapat digunakan sebagai pangan alternatif bagi penderita diabetes. Kata kunci: gula reduksi, kandungan klorofil, protein terlarut, vitamin C

Abstract

Shallot (Allium ascalonicum L.) is an important horticultural commodity with high economic value, but its productivity has declined, especially in several production centers, including Probolinggo Regency. Disease attacks are one of the factors causing the decline in production, prompting farmers to use chemicals to control the disease. The use of chemical fungicides frequently poses risks to the environment and food safety, thereby highlighting the need for eco-friendly alternatives such as biological agents (e.g., Trichoderma sp.) and organic fertilizers like guano. This study aimed to determine the effect of Trichoderma sp. and guano fertilizer on the growth and yield of shallots. The study used a Factorial Randomized Block Design (RBD) with the first factor being the dose of Trichoderma sp 0 (T1), 15 (T2), 25 (T3), 35 (T4) g/plant, and the second factor was guano fertilizer treatment at doses of 0 (G1), 35 (G2), 45 (G3), and 55 (G4) g/plant. The results showed that there was no interaction between Trichoderma sp. and guano fertilizer treatments on the growth and yield of shallots. However, both separately had a significant effect on several growth and yield parameters. Guano fertilizer had a significant effect on crown height, stem diameter, fresh and dry bulb weight, and root volume with an optimum dose of 45 g/plant. Meanwhile, the application of Trichoderma sp. had a significant effect on bulb diameter. The combination of biological agents and organic fertilizers demonstrated significant potential to enhance shallot productivity in a sustainable and environmentally responsible way.
