      Abstract
      Tanaman legundi (Vitex trifolia L.) merupakan tanaman yang dimanfaatkan sebagai obat. Daun tanaman legundi mengandung flavonoid (viteksikarpin) dan minyak atsiri yang berkhasiat sebagai trakeospasmolitik, antiasma, dan repellent. Produktivitas daun perlu ditingkatkan dalam budidaya legundi, salah satunya melalui pemangkasan. Penelitian ini bertujuan mengetahui pengaruh tinggi pemangkasan berbeda terhadap pertumbuhan dan produksi legundi. Penelitian ini menggunakan rancangan tersarang (Nested) dengan faktor utama tinggi pangkasan (10 cm, 15 cm, 20 cm, tanpa pemangkasan) dari permukaan tanah dan jumlah cabang primer yang dipelihara (2 dan 3 cabang) sebagai faktor kedua yang tersarang pada faktor utama yang diulang sebanyak 3 kali yang terdiri dari 4 tanaman dalam setiap ulangannya sehingga terdapat 96 satuan percobaan. Penelitian ini menunjukan tanaman tanpa pemangkasan menunjukan hasil terbaik pada aspek pertumbuhan dan produksi, namun tanaman dengan perlakuan pemangkasan menunjukan kecepatan pertumbuhan yang lebih pesat dan berpotensi menyamai pertumbuhan tanaman tanpa pangkas. Tanaman dengan perlakuan tinggi pangkas 20 cm menunjukkan potensi terbaik pada aspek pertumbuhan dan produksi.
       
      Three-leaved chaste tree (Vitex trifolia L.) is a plant that being used as a medicine. It leaves contains flavonoid (vitexicarpin) and essential oil that can be use as tracheospasmolytic, anti asthma, and repellent. Leaves productivity on Vitex trifolia cultivation need to be improved and one of the way was by pruning. This study aims to study the effect of different pruning height on Vitex trifolia growth and production. This research consisted two factors and used nested design with 2 treatment factors. The main factor was prunning height difference (10 cm, 15 cm, 20 cm, without pruning) from the soil surface and number of remained primary branches (2 and 3 primary branches) as a second factor that nested on the main factor. This research repeated 3 times and consisted 4 plants in every repetition so that it had 96 experimental units. This research showed that the plants without pruning gave the best results in growth and production aspects, but the pruning treatment plants had faster growth and potentially surpass the without pruning plants growth. The 20 cm pruning height treatment plants potentially give the best results in growth and production aspects.
