AbstractSoybean is one of the promising crops in the Benin agro-industrial sector, but its production is carried out at the expense of the inherent soil fertility. The present study aims to apply the DRIS (Diagnosis and Recommendation Integrated System) for nutrient status assessment in farmers’ soybean fields in northern and central Benin. Sixty-two plant leaf samples were collected during a survey carried out in 2019 in farmers’ fields. Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and zinc (Zn) concentrations in the leaf samples were analysed. DRIS norms were used to calculate the various paired nutrient ratios in the high-yielding population. Nutrient balance indices (NBI) were also determined. Nutrient requirements based on NBI were ranked according Zn > N > P > Ca > K > Mg, highlighting the importance of Zn and N in soybean nutrition. Paired nutrient ratios (N/P, N/K, Mg/N, N/Ca, Ca/P, K/Ca, Mg/Ca, Zn/Mg) were either significantly (p = 0.0001) higher or lower than those in the literature, excluding Mg/P, Mg/K, P/Zn, Ca/Zn, N/Zn K/Zn and P/K paired ratios. This observation indicates the necessity of calibrating DRIS norms taking into account local conditions and cropping systems. The DRIS model could be an important tool for refining soybean nutrient needs in a cropping system. Zinc and N levels limited soybean cultivation in farmers’ fields and must be included in the soybean fertiliser formulations to ensure optimal yield of soybean in Benin.Keywords: DRIS normsmicronutrientnutrient deficiencyplant nutritionsoil fertility management AcknowledgementsThe authors thank the Improvement of Smallholder Agricultural Productivity (PAPAPE/SAPEP-Benin) Project implemented by the Benin National Agricultural Research Institute (INRAB), funded by the Islamic Development Bank (IDB) and Benin Government, for the financial support of the present research.Disclosure statementThe authors declare no conflict of interest.
摘要大豆是贝宁农业工业中具有发展前景的作物之一，但其生产是以牺牲土壤固有肥力为代价的。本研究旨在将DRIS(诊断与推荐综合系统)应用于贝宁北部和中部农民大豆田的营养状况评估。2019年在农民田间进行的一项调查中收集了62份植物叶片样本。分析了叶片样品中氮(N)、磷(P)、钾(K)、钙(Ca)、镁(Mg)和锌(Zn)的浓度。采用DRIS规范计算高产群体的各种配对营养比。测定营养平衡指数(NBI)。基于NBI的营养需要量排序为Zn > N > P > Ca > K > Mg，凸显了Zn和N在大豆营养中的重要性。配对养分比(N/P、N/K、Mg/N、N/Ca、Ca/P、K/Ca、Mg/Ca、Zn/Mg)均显著高于或低于文献数据(P = 0.0001)，但不包括Mg/P、Mg/K、P/Zn、Ca/Zn、N/Zn、K/Zn和P/K配对。这一观察结果表明，有必要在考虑当地条件和种植制度的情况下校准DRIS规范。DRIS模型可以作为一种重要的工具来改善大豆在种植系统中的营养需求。锌和氮水平限制了大豆在农民田间的种植，必须包括在大豆肥料配方中，以确保贝宁大豆的最佳产量。作者感谢由伊斯兰开发银行(IDB)和贝宁政府资助的贝宁国家农业研究所(INRAB)实施的提高小农农业生产力(PAPAPE/SAPEP-Benin)项目为本研究提供的资金支持。声明作者声明无利益冲突。
