The effect of nitrogen and transplanting age on single bud planting system of sugarcane seed production

Sugarcane nursery with single bud planting technique is one of new technique in Indonesian which adapted from Columbia with high purity level, uniformly growth, and produce more tiller if compared with conventional technique. This study aims to determine the effect of transplanting age and nitrogen doses on sugarcane plant. The field research was conducted at Trial Research Plantation of ISRI-Pasuruan. This study using split plot design with sugarcane variety as main plot and nitrogen fertilizer dose as subplot. The result showed an interaction between transplanting age and Nitrogen fertilizer dose on sugarcane variety of Bululawang on stalk diameter, stalk length, and stalk weight. On sugarcane variety of PS 862 the interaction occurred on tiller number, stalk diameter and stalk weight. The early transplanting age gave good effect on standard N doses however increasing the N dose until N175, the seed which plant at slower transplanting age (10 weeks) showed higher yield than other transplanting age treatment.
