Penelitian ini bertujuan untuk mengetahui pengaruh pupuk organik fermentasi feses sapi menggunakan Trichoderma spp. terhadap pertumbuhan dan produksi rumput Pennisetum purpureum cv. Thailand serta menentukan dosis terbaik. Penelitian dilaksanakan pada Juli–September 2025 menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan dosis pupuk dan lima ulangan. Perlakuan terdiri atas P0 (tanpa pupuk) hingga P4 dengan peningkatan dosis pupuk organik fermentasi. Peubah yang diamati meliputi jumlah anakan, tinggi tanaman, panjang daun, produksi berat segar, dan produksi bahan kering pada umur 60 hari setelah tanam. Data dianalisis menggunakan analisis ragam dan uji Beda Nyata Terkecil. Hasil penelitian menunjukkan bahwa pemberian pupuk organik fermentasi Trichoderma spp. berpengaruh nyata (p<0,05) terhadap seluruh parameter pertumbuhan dan produksi. Perlakuan P4 memberikan hasil tertinggi. Dapat disimpulkan bahwa pupuk organik fermentasi Trichoderma spp. dosis 20 ton/ha merupakan perlakuan terbaik untuk meningkatkan pertumbuhan dan produksi rumput Pennisetum purpureum cv. Thailand.

This study aimed to evaluate the effect of fermented organic fertilizer derived from cattle feces using Trichoderma spp. on the growth and production of Pennisetum purpureum cv. Thailand and to determine the optimal dosage. The study was conducted from July to September 2025 using a Completely Randomized Design (CRD) with five fertilizer treatments and five replications. Treatments ranged from P0 (without fertilizer) to P4 with increasing doses of fermented organic fertilizer. Observed variables included number of tillers, plant height, leaf length, fresh weight yield, and dry matter production at 60 days after planting. Data were analyzed using analysis of variance followed by the Least Significant Difference test. Results indicated that fermented organic fertilizer with Trichoderma spp. significantly affected (p<0.05) all growth and production parameters. The highest values were obtained in treatment P4. It can be concluded that fermented organic fertilizer using Trichoderma spp. at a dosage of 20 tons/ha is the most effective treatment to improve the growth and production of Pennisetum purpureum cv. Thailand.
