ROMERO, Eduardo R. et al. Effects of major plantation management factors on plant cane emergence in Tucumán, Argentina. Rev. ind. agríc. Tucumán [online]. 2006, vol.83, n.1-2, pp.19-28. ISSN 1851-3018.

The purpose of this study was to evaluate the effects on plant cane emergence of the major crop management factors influencing sugarcane planting, i.e., planting dates, cultivar, water availability, and seed-cane length. Different trials, conducted between 1988 and 1997, included five cultivars, seven planting dates, three seed-cane lengths, and two water availability levels. Planting date was the most important factor, influencing percentage, rate and especially emergence duration. Cultivar effect was also important, with significant differences occurring among cultivars at similar planting dates and among planting dates for the same cultivar. A positive effect of irrigation affecting emergence rate and duration was evident. Best responses to irrigation were obtained when planting date was associated with warmer temperatures and/or when water strees was more severe. Moreover, cultivars showed differential responses to irrigation.
