      Abstract
      Katuk (Sauropus androgynous (L.) Merr.) merupakan tanaman sayuran yang berpotensi tinggi sebagai sumber pangan dan obat. Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi PGPR dan pupuk kandang ayam terhadap produktivitas tanaman katuk. Penelitian ini dilaksanakan di Kebun Percobaan Leuwikopo, IPB University dari Agustus hingga November 2024. Penelitian ini menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) Split Plot dengan pupuk kandang ayam (0 ton ha-1 , 10 ton ha-1, 20 ton ha-1 , 30 ton ha-1 ) sebagai petak utama dan PGPR (PGPR-1 dengan kandungan Trichoderma harzianum, Azospirillum sp., Rhizobium sp., Aspergillus niger, dan Pseudomonas fluorescens serta PGPR-2 dengan kandungan Rhizobium sp, Bacillus polymyxa dan Pseudomonas fluorescens) sebagai anak petak. Hasil penelitian menunjukkan bahwa pemberian PGPR memberikan pengaruh nyata lebih baik terhadap panjang cabang, tinggi tanaman, dan persentase populasi tumbuh dibandingkan dengan tidak menggunakan PGPR. Perlakuan pupuk kandang ayam dengan berbagai dosis secara umum tidak memberikan pengaruh yang nyata terhadap pertumbuhan dan hasil panen tanaman katuk. Produktivitas tertinggi diperoleh pada panen pertama dengan dosis pupuk kandang ayam 20 ton ha-1 . Tidak terdapat interaksi antara kedua perlakuan.
       
      Katuk (Sauropus androgynous (L.) Merr.) is a vegetable plant with high potential as a source of food and medicine. This research aimed to determine the effect of PGPR and chicken manure application on the productivity of katuk. The research was conducted at the Leuwikopo Experimental Garden, IPB University from August to October 2024. The experiment used a split-plot Randomized Complete Block Design (RCBD) with chicken manure (0 tons ha- -1, 10 tons ha-1, 20 tons ha-1, 30 tons ha-1) as the main plot and PGPR (PGPR-1 containing Trichoderma harzianum, Azospirillum sp., Rhizobium sp., Aspergillus niger, Pseudomonas fluorescens and PGPR-2 containing Rhizobium sp., Bacillus polymyxa, Pseudomonas fluorescens) as subplots. The result showed that the application of PGPR had a significantly better effect on branch length, plant height, and percentage of plant population growth compared to control. Chicken manure treatment with various doses generally did not have a significant effect on the growth and yield. The highest productivity was obtained in the first harvest with a dose of 20 tons ha-1 of chicken manure. There was no interaction between the two treatments.
