Both the excess and deficiency of nutrients in the soil can influence the technological quality of sugarcane stalks, and affect the quality of the juice, the fiber content, and the concentration of sucrose, which directly impact the quality and quantity of products derived from sugarcane. Thus, this study aimed to investigate the effect of nitrogen and zinc fertigation, irrigated by a central pivot, on various parameters that affect the industrial quality of sugarcane (IACSP 95-5000), in the plant and first ratoon crop cycles in a Cerrado Red Latosol soil in Brazil. The experiment was conducted under field conditions at an average altitude of 907 m in an area of the Rio Paraiso II farm of the Raízen Mill, in the municipality of Jataí, Goiás (GO). The experiment was conducted in a randomized complete blocks design and analyzed in a scheme of 4 × 5 subdivided plots, with three repetitions. The treatments consisted of four nitrogen doses (0, 60, 120, and 180 kg ha⁻¹) and five zinc doses (0, 2.5, 5.0, 7.5, and 10.0 kg ha⁻¹), on plant cane and first ratoon cane. Urea served as the source of nitrogen fertilizer and was applied in three dosages (treatments) 60 days after planting. Zn sulfate served as the zinc source and was applied in four dosages (treatments) at a single time in the planting. At harvest, ten stalks were randomly sampled from each plot and sent to the Raízen Mill agro-industrial laboratory in Jataí-GO for analysis and to determine the polarizable amount of sugar per cane (Pol % cane), polarizable amount of sugar in the juice (Pol % juice), total soluble solids (Brix %), apparent purity, wet bagasse weight (WBW), reducing sugars, total recoverable sugar (TRS), and fiber content. The highest doses of zinc (10 kg ha⁻¹) and nitrogen (180 kg ha⁻¹) had the greatest effects on sugarcane WBW and TRS.

氮锌施肥条件下甘蔗的工业品质。

土壤中养分的过量和缺乏都会影响甘蔗茎的技术质量，并影响果汁的质量，纤维含量和蔗糖浓度，这直接影响到甘蔗衍生产品的质量和数量。因此，本研究旨在调查在中心地带灌溉的氮和锌施肥对影响甘蔗（IACSP 95-5000）工业品质的各种参数的影响，以及该植物在第一个Cerrado Red作物的再生周期中的作用。巴西的Latosol土壤。该实验是在Goias（GO）的Jataí市的RaízenMill的Rio Paraiso II农场的平均海拔907 m的野外条件下进行的。该实验以随机完整块设计进行，并按4×5细分图的方案进行了分析，并进行了3次重复。处理包括四个氮剂量（0、60、120和180 kg ha^-1）和五种锌剂量（0、2.5、5.0、7.5和10.0 kg ha ^-1），分别种植在植物茎和第一个再生藤茎上。尿素作为氮肥的来源，在种植后60天以三剂（处理）施用。硫酸锌用作锌源，并在种植中一次施用四次剂量（处理）。收获时，从每个样地中随机取样十根茎，并送至Jataí-GO的RaízenMill农业工业实验室进行分析，并确定每根甘蔗的可极化糖含量（Pol％甘蔗），果汁中可极化的糖含量（果汁百分比），总可溶性固形物（白利糖％），表观纯度，湿蔗渣重量（WBW），还原糖，总可回收糖（TRS）和纤维含量。锌的最高剂量（10 kg ha ^-1）和氮（180 kg ha ^-1）对甘蔗WBW和TRS的影响最大。
