Produktivitas Tebu (Saccharum officinarum L.) Asal Bibit Bud Chips (Ujung, Tengah, Pangkal) Akibat Aplikasi Mulsa Bagasse

Abstract

The use of bud chip seeds in meeting the needs of quality seeds in an effort to increase theproduction and yield of sugar cane. The use of bagasse will be a source of nutrients forplants, so that the optimum cane growth and increase sugar cane production. The objectiveof this study was to obtain the highest yield between bud chip position, bagasse mulchdose, and to know the interaction between bud chip budding treatment with bagasse mulchtreatment on sugar cane rendement.. This research was conducted in teaching farm ofPoliteknik Negeri Lampung from June 2016 until February 2017. The experiments wereperformed using Randomized Block Design (RBD) in factorial pattern consisting of twofactors. The first factor is the position of bud chips consisting of 3 levels i.e. top, middle,and base. The second factor is bagasse mulch dosage consisting of 4 levels i.e. 0 ton.ha-1, 3ton.ha-1, 6 ton.ha-1, and 9 ton.ha-1. The result of this research showed that the position ofbud chips on the top stem has an effect on the number of stem and the productivity ofsugarcane compared to the midle and base stem position. The position of bud chipstreatment result showed no effect on the yield of sugarcane. The dose of bagasse 3 ton.ha-1,6 ton.ha-1, and 9 ton.ha-1 showed no effect on the stem diameter, the number of stem, andthe rendement of sugarcane, but affected by the dose mulch of bagasse 0 ton. ha-1. The doseof bagasse 3 ton.ha-1 showed the best effect on the number of stem per row and theproductivity of sugarcane compared to all bagasse mulch treatments. There was nointeraction between the treatment of sugarcane bud chips and mulch bagasse on allobservation variables.
