For sustainable and organic farming, organic manures such as cattle manure (CMn) and bio-nutritious substances such as royal jelly (RJ) should be used as complete or at least partial alternatives to chemical fertilizers (CFs). Therefore, two consecutive trial seasons (2018 and 2019) were conducted to study the effect of soil fertilization with CMn and/or CFs in combination with foliar spraying with RJ on growth, yield, and chemical composition of roselle (Hibiscus sabdariffa L.) plant and seed. The results indicated that spraying roselle plants with RJ resulted in a significant increase in all parameters studied over the control; however, this increase was enhanced when RJ was combined with soil fertilization. The highest values for most of the growth traits, chemical composition of seeds, sepal anthocyanin and vitamin C contents, and sepal acidity were obtained by applying 2 or 4 g RJ L−1 + (30 m3 CMn ha−1 + 50 % dose CFs). In addition, the highest values for yield components and plant chemical composition were obtained by applying 2 or 4 g RJ L−1 + (0 m3 CMn ha−1 + full dose CFs). The results also indicated that applying CMn in combination with RJ gave values mostly close to those of CFs treatment. In conclusion, the results recommend the use of RJ (2 g L−1 as a foliar feeding) along with CMn (30 m3 ha−1) as a partial alternative to chemical fertilizers for sustainably producing healthy roselle sepals.

牛粪和生物营养蜂王浆作为化肥的替代品:可持续生产有机芙蓉的潜力。

对于可持续和有机农业,牛粪 (CMn) 等有机肥料和蜂王浆 (RJ) 等生物营养物质应完全或至少部分替代化肥 (CF)。因此,连续两个试验季(2018 年和 2019 年)研究了土壤施肥与 CMn 和/或 CFs 结合叶面喷洒 RJ 对洛神花Hibiscus sabdariffa)的生长、产量和化学成分的影响。L.) 植物和种子。结果表明,与对照相比,用 RJ 喷洒洛神花植物导致所有研究参数显着增加;然而,当 RJ 与土壤施肥相结合时,这种增加会得到加强。大多数生长性状、种子化学成分、萼片花青素和维生素 C 含量以及萼片酸度的最高值是通过施用 2 或 4 克 RJ L -1 +(30 m 3 CMn ha -1 + 50 % 剂量)获得的CF)。此外,通过施用 2 或 4 g RJ L -1 + (0 m 3 CMn ha -1+ 全剂量 CF)。结果还表明,将 CMn 与 RJ 结合使用的值大多接近于 CFs 处理的值。总之,结果建议使用 RJ(2 g L -1作为叶面喂养)和 CMn(30 m 3 ha -1)作为化学肥料的部分替代品,以可持续地生产健康的玫瑰茄萼片。
