In sub-Saharan Africa, the parasitic is seriously threatening Bambara groundnuts, farmers to suffer yield losses of up to 100 %. The objective of this study was to determine the effects of phosphorus (P) application and inoculation on Bambara groundnut genotypes for growth and reproductive phrase. The experiment was conducted in 2020 at the Henderson Research Station in Mazowe, Zimbabwe in a 2 × 2 × 26 factorial design with 26 genotypes arranged in a completely randomized design (CRD) with four replications, two P rates (0 and 20 kg ha-) and two levels of inoculation (with and without ). Half of the perforated black plastic bags were inoculated with seeds. The results showed a significant (p < 0.001) interaction between P application and inoculation, leading to decreased counts after 109 days, days to maturity, days to flowering, and chlorophyll content. There was a significant (p < 0.001) interaction between Bambara groundnut genotypes and -inoculation on number of pods, pod weight, number of seeds, and grain yield. parasitism significantly (p < 0.001) decreased number of pods, pod weight, number of seeds, and grain yield across all groundnut genotypes. G2, G23, G24, and G25 genotypes exhibited tolerance to , with grain yield per plant of 4.82, 6.12, 5.65, and 5.34 g, respectively, outperforming other genotypes. It was found that the combination of 20 kg P ha with -resistant genotypes improved Bambara groundnut productivity.
在撒哈拉以南非洲，这种寄生虫严重威胁着 Bambara 花生，致使农民遭受高达 100% 的产量损失。本研究的目的是确定施磷和接种对 Bambara 花生基因型生长和生殖阶段的影响。该实验于 2020 年在津巴布韦马佐韦的亨德森研究站进行，采用 2×2×26 析因设计，26 个基因型以完全随机设计（CRD）排列，重复四次，设置两个磷水平（0 和 20 kg ha-）以及两个接种水平（接种和未接种）。一半有孔黑色塑料袋接种了[具体接种物]种子。结果表明，施磷和接种之间存在显著（p < 0.001）交互作用，导致 109 天后[具体指标]数量、成熟天数、开花天数和叶绿素含量降低。Bambara 花生基因型与接种在荚果数、荚果重量、种子数和籽粒产量方面存在显著（p < 0.001）交互作用。[寄生虫名称]寄生显著（p < 0.001）降低了所有花生基因型的荚果数、荚果重量、种子数和籽粒产量。G2、G23、G24 和 G25 基因型对[寄生虫名称]表现出耐受性，单株籽粒产量分别为 4.82、6.12、5.65 和 5.34 g，优于其他基因型。研究发现，20 kg P ha 与抗[寄生虫名称]基因型的组合提高了 Bambara 花生的生产力。
