Maintaining or improving sugarcane yields with cyclic flooding would help achieve these objectives. The purpose of this study was to evaluate the effects on shoot emergence of soaking sugarcane stalk sections in water before planting. Ten genotypes, three stalk sections, and several stalk-storage durations were investigated. Stalk sections were either stored aboveground on drained soil or immersed in water in plastic pools. Mean water temperatures ranged from 18 degree C in the mornings to 28 degree C in the afternoons. Soaking from 2 to 12 days caused more and faster emergence than not soaking. Pre-plant soaking improved shoot emergence in four genotypes, and did not affect emergence for six genotypes. Drained storage of 0 to 6 days resulted in more emergence than drained storage of 8 days. Emergence from the upper stalk section was more consistently high than from the middle or bottom stalk sections. The next research step will be to evaluate the effects on shoot emergence of flooding fields of newly-planted sugarcane. |
