      Abstract
      Ubi kayu merupakan makanan alternatif pengganti sumber karbohidrat. Kemudahan penanaman dan ketahanan terhadap kekeringan, ubi kayu sangat potensial untuk dikembangkan. Penelitian bertujuan mengetahui pengaruh penyiraman setara bulan lembab terhadap pertumbuhan ubi kayu lokal varietas Mangu, Genjah Bayam, dan IR Jonggol. Penelitian dilaksanakan di Rumah kaca Kebun Percobaan Cikabayan IPB Dramaga Bogor pada bulan Oktober 2021 sampai Februari 2022. Penelitian menggunakan Rancangan Acak Kelompok dengan dua faktor dan tiga ulangan. Faktor pertama adalah penyiraman yang terdiri dari 163,5 ml hari-1 polibag-1 (100 mm bulan-1 curah hujan) dan 196,3 ml hari-1 polibag-1 (120 mm bulan-1). Faktor kedua adalah varietas yang terdiri dari Mangu, Genjah Bayam, dan IR Jonggol. Penyiraman tidak berpengaruh nyata terhadap semua variabel pertumbuhan ubi kayu. Hasil penelitian menunjukkan varietas berpengaruh nyata terhadap semua variabel pertumbuhan ubi kayu, kecuali bobot batang, tangkai daun, dan daun. Tidak ada pengaruh interaksi antara penyiraman dan varietas pada semua variabel pertumbuhan. Pertumbuhan varietas IR Jonggol lebih tinggi dibandingkan dengan varietas Mangu dan Genjah Bayam.
       
      Cassava is an alternative food as a substitute for rice and corn. With the ease of planting and the resistance to drought, it is the potential to develop. The experiment aimed to identify the effects of watering on the growth of local cassava varieties of Mangu, Genjah Bayam, and IR Jonggol. The experiment was conducted in the Greenhouse at the Cikabayan Experimental station of IPB Dramaga, Bogor, from October 2021 to February 2022. The experiment used a randomized block design with two factors and three replications. The first factor was watering consisting of 163,5 ml day-1 polybag-1 (100 mm month-1 rainfall) and 196,3 ml day- 1 polybag-1 (120 mm month-1). The second factor was varieties consisting of Mangu, Genjah Bayam, and IR Jonggol. The watering had no significant effect on all cassava growth variables. The varieties were significantly effect to all cassava growth variables, except the weight of stem, petiole, and leaves. There was no interaction effect between watering and variety on all growth variables. The growth of varieties of IR Jonggol was higher than that of Mangu and Genjah Bayam.
