Evaluation of Promising Juice Cane Clones in Abandoned Upland Paddy Field under Rainfed Conditions in Songkhla Province

Abstract

The objective of this experiment was to evaluate five promising juice cane clones (UTj10-2, UTj10-3, UTj10-12, UTj10-15, UTj10-19) and two control varieties (Suphanburi 50 and Malaysia) on abandoned upland paddy field under rainfed conditions in Songkhla province. A Randomized Complete Block Design (RCBD) with three replications was used. We found that for planted sugarcane, UTj10-3 gave significantly greater yield than UTj10-2 and UTj10-15 but showed no significant differences in yields with the other varieties and clones. It also gave higher amount of juice than the other varieties/clones tested. For ratoon sugarcane, Suphanburi 50 attained a significantly greater yield than UTj10-2 and Malaysia but showed no significant differences with the other varieties/clones. Suphanburi 50 also gave no significantly differences in juice yield from that of Utj10-3 but showed significantly higher juice yield than the others. For planted  sugarcane, Malaysia had significantly greater %Brix than Suphanburi 50 and UTJ10-15 but showed no differences from the others. Significant differences in %Brix among varieties/clones, however were not observed for ratoon sugarcane. Overall results suggested that clone Utj10-3 was more suitable than other varieties/clones to be grown in abandoned upland paddy field under rainfed conditions.
