RESPON PERTUMBUHAN TEBU (SACCHARUM OFFICINARUM L.) PADA KEDALAMAN JURINGAN DAN DOSIS PUPUK P YANG BERBEDA

Sugarcane (Saccharum officinarum) can grow well in soil and environmental conditions that are under growing requirements accompanied by good management also. The land is a natural resource with permanent nature, while the human need for continues to increase high nutrients sugarcane causes rapid decline soil, especially monoculture sugarcane. This study aims determine effect of response growth on depth juringan dosage P fertilizer. experiment was carried out at Wedomartani Experimental Garden, Ngemplak, Sleman, Yogyakarta from January March (3 months). used factorial randomized block design. first factor rod three treatments, namely: 15 cm (K0), 30 (K1), 45 (K2). second fertilizer without (P0), 13 g / seed (P1), 22 (P2). Six treatment combinations were repeated times so there 27 experimental units. Each unit consisted two plants, total 54 plants. results showed no interaction between different depths net dosing all observed variables. Application fertilizers had single plant height, number tillers, leaves. (22 seed) resulted higher height tillers compared fertilizer.
