Abstract/ Executive Summary:

A trial with four treatments in a randomized block design with three replications was conducted at Sugarcane Research & Training Institute farm to study the effectiveness of some easily available means to minimize the breakdown of sugar into invert sugar. The variety Isd.16 was used for this investigation. Harvested canes covered with 7.0 cm thick trash significantly increased purity and the breakdown of sugar into invert sugar was Significantly reduced. Recovery was also found. to be highest. R educing sugar increased with the increase of the period of staleness of the harvested cane.

Program Area: Crop-Soil-Water Management

Commodity: Sugarcane

Objectives:

The present investigation was, therefore, undertaken to study the effectiveness of some easily available means to minimize breakdown of sugar into invert sugar.

Methodology:

An experiment was conducted at Sugarcane Research & Training Institute farm following randomized complete block design comprising four treatments with three replications. The cane variety Isd.16 was used for the present investigation and the plants were grown under rainfed condition following all standard management fertilization and other intercultural practices. The trial was conducted during the month of December. Random samples of 840 canes, representing average cane stand of the field were harvested, detached and made 84 bundles consisting of ten canes in each bundle for each sample. Then all 84 bundles were randomly grouped into four groups for four treatments on the day of harvest. Twelve such bundles, three bundles from each group representing four treatments with three replications were chemically analysed on each day at an interval of 24 hours starting from the date of harvest as 00 hours over a period of seven days. The chemical analysis was done following Horne's Dry Lead method (Horne, 1903). The four treatments were as follows: To - Canes exposed to sun (control). T1 - Canes sprayed with 1% formalin solution only once on the first day. T2 - Canes sprayed with water at 24 hours interval for the whole period of trial, T3 - Canes covered with about 7.0 cm thick sugarcane trash. Composite juice of each sample was collected to determine the reducing sugar. Reducing sugar was determined fo Howing Lane and Eynon method (Anon., 1970).

Achievement/Findings:

Since, lowest reducing sugar and highest purity and recovery percent were obtained in the treatment when the stalecanes were covered with trash in Jsd.16 and results with Co.1158 (Ali et. al., 1980) showed similar trend, it may thus be suggested that covering harvested cane with 7.0 cm deep trash would retain sucrose recovery.
