The reduction of sugarcane interrow spacing has the potential to increase crop yield, but research results concerning sugarcane cultivation in Brazil and worldwide remain inconclusive. Therefore, the objective of this review was to evaluate the influence of interrow spacing on the stalk fresh yield (SFY) of sugarcane and to identify the most appropriate interrow spacing in different climates and water regimes (irrigated or rainfed). In this study, a broad review of published studies was conducted to gather experimental data and evaluate the influence of interrow spacing on sugarcane SFY. A total of 28 relevant studies was used, including 170 field experiments in nine countries. Field experimental data were grouped on the basis of similarity of climate, using hierarchical cluster analysis for rainfed and irrigated experiments. Analysis of variance was used to evaluate whether there was a variation between the SFY values, and Tukey tests were applied to compare the SFY means for each interrow spacing. The results indicated that SFY significantly increased as interrow spacing was reduced. Interrow spacing of 90 cm had the greatest SFY (p < .01) for both irrigated and rainfed treatments. The lowest average SFY values were among spacings from 150 to 180 cm, which are most frequently used in the largest‐producing countries, depending on the climate zone and water regime. Despite the increase in yield, the use of narrower interrow spacing is limited mainly due to the soil compaction and sugarcane stool damage caused by the currently used tillage and harvesting machines.

行列间距和甘蔗单产在多种气候中的重大回顾

减少甘蔗行距有可能增加作物产量，但有关巴西和全世界甘蔗种植的研究结果尚无定论。因此，本次审查的目的是评估行距对甘蔗秸秆新鲜产量（SFY）的影响，并确定在不同气候和水域（灌溉或雨养）下最合适的行距。在这项研究中，进行了广泛的综述，以收集实验数据并评估行距对甘蔗SFY的影响。总共使用了28项相关研究，包括在9个国家进行的170项现场实验。根据气候相似性，对田间试验数据进行分组，对雨养和灌溉试验进行分层聚类分析。方差分析用于评估SFY值之间是否存在差异，Tukey检验用于比较每个行距的SFY均值。结果表明，随着行距的减小，SFY显着增加。行距90 cm具有最大的SFY（p  <.01），适用于灌溉和雨养处理。SFY的最低平均值介于150到180 cm之间，这在最大的生产国中最常用，具体取决于气候区和水域。尽管产量增加了，但是由于当前使用的耕种和收割机造成的土壤压实和甘蔗粪便损坏，限制了行距的缩小。
