Abstract/ Executive Summary:

Phosphate in cane juice is generally present in the order of 250-400 ppm level. If phosphate content is low in cane juice, it has to be made upto the level required for best juice clarification by adding phosphate (40-45 % P₂O₅) in slurry or in solution. The P₂O₅ content at 350ppm level is supposed to be optimum in most of the cane juice in order to get good juice clarification. The varying level of phosphates in cane juice may be associated due to many factors e.g. soil condition, phosphatic fertilizer application and variety. This study is specially aimed to determine the level of available phosphate in different sugarcane varieties/clones for better juice clarification. The clones I 112-01( 350 ppm), I 6-04 (395 ppm) and I 189-04 (328 ppm) under ZYT-III test stages were recorded to contain phosphate at desired level. The clones I 25-04 (325 ppm), I 139-05 ( 303 ppm), I 1150-05 (317 ppm) and Isd 18 T2 (328 ppm) under ZYT-II test stages were also recorded to contain phosphate at desired level.

Keywords: Phosphate, Sugarcane, Juice

Location: Bangladesh Sugarcane Research Institute, Ishurdi-6620, Pabna.

Start Date: 10-10-2006

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Sugarcane

Objectives:

i) To determine the level of phosphate in different sugarcane varieties/clones for better juice clarification. ii) To identify varieties/clones containing higher phosphate level to help cane breeder for further crossing programme..

Methodology:

The experiment will be conducted at BSRI laboratory. Sugarcane samples were collected from BSRI farm. After crushing cane juice was chemically analysed to determine phosphate content by Ammonium molybdate /Ascorbic acid graphical method
