The objective of the research was to determine the different of growth and development of some
cassava genotype. The research was conducted at Desa Tanjung Selamat, Kecamatan Sunggal,
Kabupaten Deli Serdang from July to December 2016. The research was arranged by Randomized
Block Design for one variety (Adira-1) and 6 genotype (Valencia, Malang, Malaysia, Lampung,
and Putih) each treatment was replicated 4 t imes.The result showed that Pulut genotype has the
highest average plant heigth (277,48 cm) that is significantly different from the others accept
Malang genotype, Malang genotype has the highest average diameter (31,26 mm) wich is
significantly different from the others. The highest Lobus length character is at Pulut genotype
(22,6 cm) and the highest lobus wide is at Malang genotype (7,3 cm). The highest leaf length
petiole character is at Putih genotype (31,4 cm), and the highest of leaf lobus character at Adira 1
and Lampung genotype are 5 leaves lobus. There are was different among genotypes (Valencia,
Malang, Malaysia, Lampung, and Putih) and variety (Adira-1) on the average weight of (6 month
after planted) cassava.
Penelitian ini bertujuan untuk mengetahui pertumbuhan dan perkembangan dari beberapa genotip ubikayu. Penelitian dilaksanakan di Desa Tanjung Selamat, Kecamatan Sunggal, Kabupaten Deli Serdang dari bulan Juli sampai Desember 2016. Peneliti menggunakan Rancangan Acak Kelompok dengan satu varietas (Adira-1) dan 6 genotip (Valencia, Malang, Malaysia, Lampung, dan Putih) pada tiap perlakuan dengan 4 ulangan. Hasil penelitian menunjukkan bahwa genotip Pulut memiliki rataan tinggi tanaman tertinggi (277,48 cm) ,serta memiliki rataan diameter tertinggi terdapat pada genotip Malang (31,26 mm) yang mana berbeda nyata dengan yang lainnya. Karakter panjang lobus tertinggi terdapat pada genotip Pulut (22,6 cm) dan lebar lobus tertinggi terdapat pada genotip Malang (7,3 cm). Pada karakter panjang petiole tertinggi terdapat pada genotip Putih (31,4 cm), dan pada karakter jumlah lobus daun tertinggi terdapat pada varietas Adira 1 dan genotip gajah yaitu berjumlah 5 lobus daun. Tidak berbeda nyata antara genotip (Valencia, Malang, Malaysia, Lampung, dan Putih) dan varietas (Adira-1) pada rataan bobot ubikayu (umur 6 bulan).
