A greenhouse experiment was performed to elucidate the potency of Prosopis juliflora charcoal (PJC) and banana waste compost (BWC) to improve soil fertility and enhance plant growth rate. Plantlets of Ricinus communis were grown in 0, 400, and 800 mg kg⁻¹ Pb-spiked soil ameliorated with P. juliflora charcoal and banana waste compost at 0, 5%, and 10% (w/w) for 60 days. PJC and BWC significantly (p < 0.05) increased plant growth parameters, that is, number of leaves, node number, plant height, and leaf diameter and reduced oxidative stress manifested by the lesser production of proline, hydrogen peroxide (H₂O₂), and malondialdehyde (MDA) with respect to control plants. Soil usage of PJC at 10% decreased the Pb accumulation by 61%, whereas BWC decreased Pb concentration in roots by 56% concerning control. Field emission scanning electron microscope (FE-SEM) coupled with energy-dispersive X-ray spectroscopy (EDS) showed high macro and microspores on the surface of charcoal while banana compost showed significant raise in the nutrient content (N, P, K, Zn, Ca, Fe, and Mg). Thermogravimetric (TG) and Fourier-transform infrared spectroscopy (FTIR) analysis of banana compost showed enhanced molar convolution of carbohydrate composites and nitrogen content. These findings pave a clear understanding that PJC and BWC are recalcitrant for Pb phytotoxicity and can also be used as nutrient-rich composites for increased crop production.

进行了温室实验，以阐明Prosopis juliflora木炭（PJC）和香蕉废料堆肥（BWC）的效力，以提高土壤肥力并提高植物生长速度。在0、400和800 mg kg ^-1的掺有P. juliflora木炭和香蕉废料堆肥的PB掺加土壤中，分别以0、5％和10％（w / w）种植Ricinus communis的苗，生长60天。PJC和BWC显着（p  <0.05）增加了植物生长参数，即叶片数，节数，植物高度和叶片直径，并且由于脯氨酸，过氧化氢（H ₂ O _2）的减少而表现出氧化应激的降低。）和丙二醛（MDA）（相对于对照植物）。在控制方面，土壤PJC用量为10％时，铅的积累量降低了61％，而BWC降低了根部中的Pb浓度，降低了56％。场发射扫描电子显微镜（FE-SEM）与能量色散X射线光谱仪（EDS）结合显示出木炭表面的大量大孢子和小孢子，而香蕉堆肥的养分含量（N，P，K，Zn显着增加） ，钙，铁和镁）。香蕉堆肥的热重（TG）和傅里叶变换红外光谱（FTIR）分析表明，碳水化合物复合物的摩尔卷积和氮含量增加。这些发现清楚地认识到PJC和BWC对Pb的植物毒性具有顽固性，也可以用作营养丰富的复合物以增加作物产量。
