The aim of this study was to assess the influence of hydrogel and zinc oxide nanoparticles on quinoa germination and establishment. Various doses of a commercial potassium-based hydrogel (0, 5, 7, and 9 g), each dissolved in one liter of rainwater, were applied. Additionally, 1.5 g of zinc oxide nanoparticles (ZnO-NP) and pre-crushed nitrogen fertilizer, at a rate of 1.6 kg/ha, were added to the solution to achieve a homogeneous mixture. Following the application of hydrogel in the 10-linear-meter rows corresponding to each treatment area in every block, 25 seeds per linear meter of the "Blanca de Juli" quinoa cultivar were sown with a 4 cm spacing between the seeds. Subsequently, a thin layer of soil, approximately 0.5 cm thick, was used to cover the seeds. Ten seedlings were randomly selected and labeled for subsequent evaluations. The experimental design employed in this research was a completely randomized block design. The collected data underwent an analysis of variance, and the means of all the treatments were compared using Tukey's test with a 5% probability. Height and diameter evaluations of the plant neck were conducted every 45 days. The doses used in this study (5, 7, and 9 g of hydrogel per liter of water) significantly enhanced seed germination and increased the number of plants per linear meter (from 82.00 to 90.33) compared to the control dose without hydrogel (14.66), which resulted in an average of one plant per linear meter.
本研究的目的是评估水凝胶和氧化锌纳米颗粒对藜麦发芽和生长的影响。使用了不同剂量的市售钾基水凝胶（0、5、7和9克），每种剂量均溶解在一升雨水中。此外，向溶液中添加了1.5克氧化锌纳米颗粒（ZnO-NP）和按1.6千克/公顷的用量预先粉碎的氮肥，以实现均匀混合。在每个试验区对应各处理区域的10线性米长的行中施用凝胶后，以每线性米播种25粒“Blanca de Juli”藜麦品种种子，种子间距为4厘米。随后，用约0.5厘米厚的薄层土壤覆盖种子。随机选择10株幼苗并进行标记，以供后续评估。本研究采用的实验设计是完全随机区组设计。对收集到的数据进行方差分析，并使用概率为5%的Tukey检验比较所有处理的平均值。每隔45天对植物颈部的高度和直径进行评估。与不使用水凝胶的对照剂量（每线性米14.66株，平均每线性米1株）相比，本研究中使用的剂量（每升水5、7和9克水凝胶）显著提高了种子发芽率，并增加了每线性米植株数量（从82.00株增加到90.33株）。
