For the need for expansion in the production of sugarcane, especially in regions that do not yet produce it significantly, there is a necessity for new studies in such areas, such as the cerrado-pantanal transition region. Therefore, the present study aimed to evaluate the agronomic performance of the crop through different soil management and billets sizes in the region. The experiment was conducted at the State University of Mato Grosso do Sul, in Aquidauana, Mato Grosso do Sul, in the 2012/2013 harvest. The design was in blocks with randomized treatments, in 2 × 3 subdivided plots, with treatments consisting of the combination of two soil management (no-tillage and conventional tillage systems) and three billet sizes (10, 20 and 40 cm), with four replications. The variety used was RB867515, and the variables analyzed were number of tillers, plant height, percentage of gaps, stem diameter, stem mass, productivity and total recoverable sugar. It was concluded that the use of billets of 20 cm in length positively influenced the vegetative development of sugarcane, but it did not translate directly into productivity. The planting system also did not directly influence the agronomic performance of the crop.

免耕和常规耕作方式下不同尺寸小方坯甘蔗行距缩小的农艺表现

由于需要扩大甘蔗生产，特别是在尚未大量生产甘蔗的地区，因此有必要在诸如塞拉多-潘塔纳尔河过渡区等领域进行新的研究。因此，本研究旨在通过该地区不同的土壤管理和坯料尺寸来评估农作物的农艺性能。该实验是在2012/2013年收成的南马托格罗索州州立大学马托格罗索州州立大学进行的。设计采用成块的方式，在2×3细分地块中进行随机处理，处理包括两种土壤管理（免耕和常规耕作系统）和三种坯料尺寸（10、20和40厘米）的组合，其中四种复制。使用的品种为RB867515，分析的变量为分ers数量，株高，间隙百分比，茎直径，茎质量，生产力和总可采糖量。结论是，使用长度为20 cm的钢坯会对甘蔗的营养发育产生积极影响，但并未直接转化为生产力。种植系统也没有直接影响农作物的农艺性能。
