Abstrak. Tanaman kacang panjang (Vigna sinensis L.) ialah spesies tumbuhan yang tergolong ke dalam famili Leguminosae. Hasil tanaman kacang panjang dapat ditingkatkan melalui pemupukan dan pemangkasan. Tujuan dilaksanakannya penelitian ini untuk mengetahui pengaruh pemupukan POC bonggol pisang dan pemangkasan terhadap perkembangan dan hasil tanaman kacang panjang. Penelitian ini telah dilakukan pada bulan Juni hingga Agustus 2022, dilahan percobaan 2 Sektor Timur dan LaboratoriumTekhnologi Benih Universitas Syiah Kuala. Rancangan Acak Kelompok faktorial 3 x 3 dengan 3 ulangan, 9 perlakuan dan 27 satuan percobaan. Setiap perlakuan terdiri dari 3 tanaman, sehingga total 81 tanaman. Kedua faktor tersebut ialah faktor konsentrasi POC bonggol pisang yang ditetapkan sebesar 30%, 50%, dan 70%, serta faktor pangkas yang ditetapkan pada 3 taraf yaitu tanpa pangkas, pangkas cabang, dan pangkas pucuk. Hasil penelitian ini menunjukkan bahwa konsentrasi POC bonggol pisang berpengaruh tidak nyata terhadap semua parameter. Pertumbuhan dan hasil tanaman cenderung lebih baik pada konsentrasi POC 70%. Pada perlakuan pemangkasan berpengaruh sangat nyata terhadap diameter batang umur 28 HST dan tidak berpengaruh nyata terhadap parameter lainnya, pertumbuhan dan hasil tanaman terbaik dijumpai pada pemangkasan cabang lateral. Interaksi antara konsentrasi POC bonggol pisang dan pemangkasan berpengaruh nyata terhadap tinggi tanaman umur 21 HST dan bobot polong pertanaman. Pertumbuhan dan hasil terbaik pada kombinasi konsentrasi POC 70% dan pemangkasan pucuk.

Abstract. Long bean (Vigna sinensis L.) is a plant species belonging to the Leguminosae family. Yield of long bean plants can be increased through fertilizing and pruning. The purpose of this study was to determine the effect of banana weevil Liquid Organic Fertilizer and pruning on the development and yield of long bean plants. This research was conducted from June to August 2022, in the East Sector 2 experimental field and the Seed Technology Laboratory at Syiah Kuala University. Randomized block design 3 x 3 factorial with 3 replications, 9 treatments and 27 experimental units. Each treatment consisted of 3 plants, so a total of 81 plants. These two factors were the banana weevil Liquid Organic Fertilizer concentration factor which was set at 30%, 50%, and 70%, as well as the pruning factor which was set at 3 levels, namely without pruning, pruning branches, and pruning shoots. The results of this study indicated that the Liquid Organic Fertilizer concentration of the banana weevil had no significant effect on all parameters. Plant growth and yield tended to be better at 70% Liquid Organic Fertilizer concentration. The pruning treatment had a very significant effect on stem diameter at 28 HST and had no significant effect on other parameters. The best plant growth and yield was found in pruning lateral branches. The interaction between POC concentrations of banana weevils and pruning had a significant effect on plant height at 21 HST and pod weight of the plants. The best growth and yield was at a combination of 70% concentration and shoot pruning.
