ABSTRACT

Cane ripeners have been comercially used in Indonesian sugar industry. Recently, there are three new chemical products, such as: Fluazfop Buthyl 150 g/l product (FB-1), Fluazfop Buthyl 125 g/l product (FB-2) and Glyphosate Potassium 620 g/l product (GP), that potentially can be used to spur maturation of cane. In order to study a performance of the three chemicals as cane ripeners, at the Indonesian Sugar Research Institute (ISRI) Pasuruan was conducted efication research with use PS 951 as a cane variety tested. In this experiment was also studied Isoprophylamine Glyphosate (IG) as a standar recommended ripeners. The parameter observed were: (1) maturation factor (MF) and (2) components of juice qualities of cane, such as: brix, pol, purity, and sucrose content, (3) cane yield, (4) toxicity rate of cane to chemicals tested, and (5) growth performance of ratoon crop (RC). The results of the experiment showed that FB-1, FB-2 and GP were able to spur the maturation and increase juice quality of PS 951 cane variety tested, and it were similar with showed by IG on 0,80 l product/ha. All the chemicals tested, include IG, caused clorotic symptom on leaves and dead of growth point but it were not reduce the cane yield. Moreover, the poisoning symptoms on PC were not depressed the cane growth performance of RC. The significantly effect of the three chemicals tested as ripeners were found at 4-5 weeks after treatment (wat) and the effective dosage aplications were 0,60-0,90 l product/ha.

Key words: Cane ripeners, Fluazifop butyl 150 g/l product (FB-1), Fluazifop butyl 125 g/l product (FB-2), Glyphosate Potassium (GP), Isopro¬phyl¬amine glyphosate (IG), PS 951

Many sugar industries, beet and cane, would predict that in the future they will produce a wide range of products which could include sugar. To realize this prediction, new varieties must be designed, production practices improved and alternative processing techniques developed. Sugarcane breeding and selection has moved far beyond the "old days" of crossing the best parents and hoping to select the best segregate as a potential new variety. Modern breeding procedures and biotechnology offer greater efficiency. Typically, varieties are selected on the basis of high yield of sugar and characteristics important to agronomic production and pest resistance in each growing region. It is anticipated that the “ultimate” variety of the future will involve much more analysis than the typically measured juice quality characteristics of brix and pol which along with tonnage, stubbling ability and fiber content, can predict yield of sugar per unit area. Once produced, high yielding varieties for various products need to be grown in a sustainable manner that provides maximum production with minimal environmental and economic impact. Processing of these varieties will need to accommodate the specific product being produced whether sugar, energy or some other product. To demonstrate the importance of quality characteristics of future varieties, Sugar Processing Research Institute has investigated the presence of components that could either enhance or inhibit production of various products from sugarcane. Significant variability among and within species of sugarcane and related genera have been found for starch, polysaccharides, ash, cations, anions, organic acids and other parameters. This presentation includes this data and the potential importance of these parameters in future varieties, its importance in a sustainable production system and its importance in processing needs.
