Respon Beberapa Genotipe dan Pelukaan Stek (Pengeratan) terhadap Pertumbuhan Tanaman Ubi Kayu (Manihot esculenta Crantz.) untuk Meningkatkan Produktivitas

The respons genotype and wounded treatment on the growth of plant cassava (Manihot esculenta Crantz) to raise the productivity

Abstract

Penelitian bertujuan untuk melihat respon dari genotipe dan pelukaan stek terhadap pertumbuhan tanaman ubi kayu untuk meningkatkan produktivitas. Penelitian dilaksanakan di Desa Pegajahan, Kabupaten Deli Serdang, Sumatera Utara dari bulan Maret sampai Juni 2015. Penelitian menggunakan Rancangan Petak Terpisah pola RAK dengan petak utama yaitu genotipe (G) yang terdiri dari Varietas Adira 1, Genotipe Malaysia dan Genotipe Roti. Anak petak yaitu pelukaan stek (K) terdiri dari tanpa kerat, kerat 1, dan kerat 2. Perlakuan diulang 3 kali. Hasil penelitian menunjukkan bahwa genotipe berbeda nyata terhadap parameter diameter batang 8 MST dan 12 MST, namun tidak berbeda nyata pada diameter tinggi tanaman, jumlah ubi kayu, panjang ubi kayu, bobot ubi kayu. Pelukaan stek dan interaksi tidak berbeda nyata.

The main goal of this research is to evaluate the respons of genotype and wounded treatment on growth of cassava to raise the productivity. The research was conducted at Pegajahan Village, district of Serdang Bedagai, North Sumatra from March to June 2015. The experiment was arranged by Split Plot Design with genotype (G) as mainplot, which consists of one variety i.e., Adira 1, and two genotypes i.e., Malaysia and Roti. Wounded treatments (K) is subplot that consist of three parts i.e., no wounded treatmen, one wounded treatment and two wounded treatmen. The treatments were replicated three times. The results showed that the genotype were significantly different to the parameter stem diameter of 8 WAP and 12 WAP, but not significant plant height, number of cassava roots, long of cassava roots, weight of cassava roots. The wounded treatmen and interaction not significant.
