The integrated application of inorganic fertilizers, organic fertilizers, and biofertilizers helps sustain the nutrient pool and benefits the soil quality, thereby boosting plant health. The effect of different combinations of biofertilizers (consortium biofertilizer [CBF]-non-rhizobial PGPR), inorganic fertilizers, and organic fertilizers on soil health, growth, and yield of cowpea was evaluated by conducting a field experiment. The application of NFYM + CBF resulted in significantly higher populations of bacteria, fungi, PSB, and diazotroph, as well as soil dehydrogenase and alkaline phosphatase enzyme activities. However, the application of N FYM recorded a significantly higher actinomycetes population. The application of N FYM + CBF resulted in significantly higher soil OC, available nitrogen, phosphorus, and potassium. The soil pH was recorded to be highest in control, and soil EC was recorded to be lowest in control. The plant uptake of nitrogen, phosphorus, and potassium was significantly higher with N FYM + NP + CBF. The root-shoot biomass, number of leaves, nodules/plant, number of pods/plants, pod biomass, pod length, and pod width were significantly higher in treatment having N FYM + NP + CBF. However, the height of the plant, number of branches, and biomass of leaves were highest in treatment with N FYM + NP + CBF. The pod and stover yield were significantly higher in treatment with N FYM + NP + CBF. The results showed that the integrated application of non-rhizobial PGPR along with organic and inorganic fertilizer helps to improve overall soil health, quality, and plant growth of forage cowpea contributing to an increase in crop yield.
无机肥料、有机肥料和生物肥料的综合应用有助于维持养分库，有益于土壤质量，从而促进植物健康。通过田间试验评估了不同生物肥料（联合生物肥料[CBF]-非根瘤固氮菌 PGPR）、无机肥料和有机肥料组合对豇豆土壤健康、生长和产量的影响。应用 NFYM+CBF 可显著增加细菌、真菌、PSB 和固氮菌的数量，以及土壤脱氢酶和碱性磷酸酶的活性。然而，应用 N FYM 可显著增加放线菌的数量。应用 N FYM+CBF 可显著提高土壤 OC、有效氮、磷和钾。对照处理的土壤 pH 值最高，对照处理的土壤 EC 值最低。N FYM+NP+CBF 处理可显著提高植物对氮、磷和钾的吸收。N FYM+NP+CBF 处理的根-茎生物量、叶片数、根瘤/株、荚数/株、荚生物量、荚长和荚宽均显著较高。然而，植物高度、分枝数和叶片生物量最高的处理是 N FYM+NP+CBF。N FYM+NP+CBF 处理的荚和秸秆产量显著较高。结果表明，非根瘤固氮菌与有机和无机肥料的综合应用有助于提高整体土壤健康、质量和饲料豇豆的植物生长，从而增加作物产量。
