| Abstract | Harvest planning in sugarcane attempts to optimize the crop's economic return based on the concept that sugarcane presents, along the cropping season, a period during which the maximum concentration of sucrose occurs in the stalks. This work consisted of studies that focused on the influences of edaphic-climatic factors on yield and total recoverable sugars. The hypothesis was tested that an interaction exists between the planting and harvesting seasons, as well as the hypothesis that an interaction exists between the whole-stalk and the bud seedling treatments with each planting season. Data from a research conducted at COPERSUCAR's Experimental Field – Piracicaba/SP, in a Red Eutrophic Latosol, were used. A random blocks design with strip split-plots was used, where sub-subplots were allocated within strips. Treatments were planting seasons (November, January, March, May), with harvesting seasons represented by strips (May, July, September, November), while sub-subtreatments consisted of bud and whole-stalk seedlings. The variables measured were: tons of sugarcane stalks (TSS) and tons of sugar per hectare (TSH), and total recoverable sugar (TRS). The ratoon (second cut) was evaluated in the same manner as the 1 cut, when sugarcane was 12 months old. Three experiments were installed, each consisting of one variety: SP 701143, NA 56-79, and SP 71-1406. The experiments were installed and |
