The method used was a factorial randomized block design with<br />three replications. The first factor was cutting height of 10 cm, 20 cm and 30 cm from soil surface. The second factor was five<br />genotypes selected from previous study, namely Cimelati, Hipa-5, Rokan, IPB106-7-47-DJ-1 and IPB106-F-8-1. The results<br />showed that combination of genotypes and cutting height affected ratoon yield. Cutting height of 20 cm increased the number<br />of filled grain in almost all genotypes, increased growth rate of ratoon to 1.5 cm day-1 and increased growth uniformity of<br />ratoon of Cimelati, Hipa-5 and Rokan geontypes, with production 3.0 ton ha-1, 2.8 ton ha-1 and 2.2 ton ha-1, equal with 57.2%,<br />60.1%, 52.7%, of the main crop respectively. Cutting height of 10 cm above soil surface showed the best results for IPB106-<br />7-47-DJ-1 and IPB106-F-8-1 genotypes, with the highest yield of ratoon 2.1 ton ha-1 and 1.5 ton ha-1, equal with 45.8% and<br />35.4% of the main crop respectively.<br />Keywords: cutting height, ratoon, yield</p&gt;}, number={1}, journal={Jurnal Agronomi Indonesia (Indonesian Journal of Agronomy)}, author={,Susilawati}, year={2017}, month={Jan.} }
