Abstract

Background: Calcium nitrate is a widely used fertilizer in the preparation of nutrient solutions. However, there is still a need to determine the effects of different levels of calcium nitrate on the Persian cucumber crop to optimize fertilization practices and improve crop yield. Objective: To determine the effects of two levels of calcium nitrate in the nutrient solution on the growth, yield, and nutrient content of two Persian cucumber hybrids (Bereket and Cruz). Methodology: The experiment was carried out in a completely randomized design in a factorial arrangement (two hybrids and two nutrient solutions) under greenhouse conditions. Results: The nutrient solution with 11 meq L-1 of calcium nitrate increased the concentration of nitrate and calcium in the petiole sap of the Cruz hybrid in the flowering stage; however, the yield of both hybrids decreased. On the other hand, the nutrient solution with 9 meq L-1 of calcium nitrate increased the number of fruits of both hybrids and the yield per plant of the Cruz hybrid. Implications: The Cruz hybrid showed to be more efficient in calcium uptake than the Bereket hybrid, which is interesting since it could require less calcium application without affecting yield. However, other studies are necessary to expand this information. Conclusion: The nutrient solution containing 9 meq L-1 of calcium nitrate showed a significant increase in the number of fruits per plant for both the Cruz and Bereket hybrids. This highlights the importance of appropriate calcium nitrate supplementation in the nutrient solution, as it enhances the production of hydroponically grown Persian cucumbers.

施用两种浓度的硝酸钙对波斯黄瓜汁液养分、生长和产量的影响

背景：硝酸钙是一种广泛用于配制营养液的肥料。然而，仍有必要确定不同含量的硝酸钙对波斯黄瓜作物的影响，以优化施肥方法，提高作物产量。目的确定营养液中两种浓度的硝酸钙对两种波斯黄瓜杂交种（Bereket 和 Cruz）的生长、产量和营养成分的影响。实验方法试验在温室条件下进行，采用完全随机设计的因子排列（两种杂交种和两种营养液）。实验结果含有 11 meq L-1 硝酸钙的营养液提高了克鲁兹杂交种花期叶柄汁液中硝酸盐和钙的浓度，但两种杂交种的产量都有所下降。另一方面，9 meq L-1 硝酸钙营养液增加了两种杂交种的果实数量和克鲁兹杂交种的单株产量。影响：克鲁兹杂交种比贝雷凯特杂交种的钙吸收效率更高，这一点很有意思，因为它可以减少钙的施用量而不影响产量。不过，有必要进行其他研究来扩展这一信息。结论含有 9 meq L-1 硝酸钙的营养液显示，克鲁兹和贝雷凯特杂交种的单株果实数都有显著增加。这突出了在营养液中适当补充硝酸钙的重要性，因为它能提高水培波斯黄瓜的产量。

期刊介绍： The journal is an international peer-reviewed publication devoted to disseminate original information contributing to the understanding and development of agroecosystems in tropical and subtropical areas. The Journal recognizes the multidisciplinary nature of its scope and encourages the submission of original manuscripts from all of the disciplines involved in this area. Original contributions are welcomed in relation to the study of particular components of the agroecosystems (i.e. plant, animal, soil) as well as the resulting interactions and their relationship/impact on society and environment. The journal does not received manuscripts based solely on economic acpects o food technology.
