Sugarcane ( Saccharum officinarum L.) yield is affected by climate, soil and management. The main approach used in Brazil defines the suitable area for growth considering soil and climate data, without considering the capacity of local management in reducing yield-limiting factors. Thus, the aim of this study is to characterize homogenous areas using sugarcane actual yield, climate, total plant-available soil water capacity (TASW), and production intensity data. The study was conducted in the Goiás state, totalizing 246 counties. The first step was to group areas based on actual yield obtained from 1973 to 2016. The groups were characterized considering climate (rainfall and air temperature), soil (TASW), and sugarcane production data. Actual sugarcane yield formed eight homogenous groups, numbered 1–8, containing 12 and 50 counties each group. The counties groups with a higher yield have a higher production intensity. They are near mills, have a higher TASW, and are divided in traditional and recent expansion areas. The counties groups with a lower yield have a lower TASW and a higher air temperature. Hotter regions are in the western and northern state border. New areas of expansion were available near current sugarcane mills within areas with a higher TASW. Thus, preferential regions were defined by associating edaphoclimatic conditions with high yield. These areas can receive support to improve sugarcane production.

使用巴西戈亚斯州的实际产量和土壤气候条件数据表征甘蔗产区

甘蔗 ( Saccharum officinarum L.) 产量受气候、土壤和管理的影响。巴西使用的主要方法是根据土壤和气候数据确定适宜生长的区域，而没有考虑当地管理在减少产量限制因素方面的能力。因此，本研究的目的是使用甘蔗实际产量、气候、植物可用土壤总水分容量 (TASW) 和生产强度数据来表征同质区域。该研究在戈亚斯州进行，共有 246 个县。第一步是根据 1973 年至 2016 年获得的实际产量对区域进行分组。根据气候（降雨和气温）、土壤 (TASW) 和甘蔗生产数据对这些组进行表征。实际甘蔗产量形成了 8 个同质组，编号为 1-8，每组包含 12 和 50 个县。产量较高的县组生产强度较高。它们靠近工厂，具有较高的 TASW，并分为传统和近期扩张区。产量较低的县组具有较低的 TASW 和较高的气温。较热的地区位于西部和北部州边界。在 TASW 较高的区域内，现有甘蔗厂附近有新的扩张区域。因此，优先区域是通过将土壤气候条件与高产量相关联来定义的。这些地区可以获得支持以提高甘蔗产量。较热的地区位于西部和北部州边界。在 TASW 较高的区域内，现有甘蔗厂附近有新的扩张区域。因此，优先区域是通过将土壤气候条件与高产量相关联来定义的。这些地区可以获得支持以提高甘蔗产量。较热的地区位于西部和北部州边界。在 TASW 较高的区域内，现有甘蔗厂附近有新的扩张区域。因此，优先区域是通过将土壤气候条件与高产量相关联来定义的。这些地区可以获得支持以提高甘蔗产量。
