The influence of altitude of the place on the vegetative growth of several varieties of sugarcane (saccharum officinarum l.)

This study is aimed at finding out vegetative growth of some varieties of sugarcane on different altitudes. The study applied Factorial Randomized Block Design comprising two factors. The first factor was varieties of consisting of three levels: BM 13579, Ps. 92-1, and Ps. 89-1. The second factor was altitudes of the land with three different levels of altitudes: Kebun Saentis (15 MASL), district of Pancurbatu (+/- 300 MASL), and district of Sibolangit (+/- 700 MASL). The study resulted in that variety of sugarcane, altitudes, and the interaction of both variables affected these: the leaf area on observations of 21, 42, 63, and 84 daps, number of tillers, root volume, nutrient uptake on observation 84 daps. The best quality of the sugarcane varieties was variety Ps. 92-1 on altitude 15 MASL (Kebun Saentis), followed by an altitude +/- 300 MASL (district of Pancurbatu), and then on +/- 700 MASL (district of Sibolangit); while the worst quality of the variety was variety BM 13579 of altitude 15 MASL (Kebun Saentis).
