Field experiment was conducted to assess the effect of treated sewage water on physiological attributes, productivity, micronutrient and heavy metal content in pearl millet (Pennisetum glaucum L.) under different nutrient sources during 2018 and 2019. The experiment consisted of 16 treatment combinations with two irrigation sources [canal and treated sewage water], two levels of farm yard manure [2.5 and 5 t ha⁻¹] that assisted in main plots and four fertility levels [control, 50, 75 and 100% recommended dose of fertilizer (RDF, 156.25 kg N and 62.5 kg P₂O₅ ha⁻¹)] that assisted in subplots in split-plot design using three replications. The results revealed that the irrigation sources did not influence significantly growth parameters, protein percent, fat acidity, canopy temperature and grain yield. However, canal and treated sewage water differ significantly in respect of photosynthesis and chlorophyll content. Further, data showed that different fertility levels differed significantly (P ≤ 0.05). Higher leaf water potential, canopy temperature, photosynthesis and chlorophyll content were recorded with the application of 100% RDF over control, 50 and 75% RDF. The concentration of heavy metals (Pb, Cd, Ni and Co) decreased with increasing levels of FYM application from 2.5 to 5 tha⁻¹ in plant, while in soils these were increased with increasing levels of FYM application. The interaction effect showed significant effect on pooled grain yield of pearl millet. Application of 100% RDF along with FYM @ 5.0 t/ha produced higher yield over 75% RDF + FYM @ 5.0 tha⁻¹ and 50% RDF + FYM @ 5.0 tha⁻¹ irrespective of irrigation sources. This clearly showed that higher application of FYM reduces the heavy metal accumulation in pearl millet irrigated with treated sewage water.

在2018年和2019年，进行了田间试验以评估处理后的污水对不同营养源下小米（Pennisetum glaucum L.）的生理特性，生产力，微量元素和重金属含量的影响。该实验包括16种处理组合，其中两种灌溉水源[运河和处理过的污水]，两个水平的农田粪便[2.5和5吨公顷^-1 ]辅助主要土地和四个肥力水平[对照，建议的肥料剂量50、75和100％（RDF， 156.25千克N和62.5千克P ₂ O ₅公顷^-1）]使用三个复制项帮助进行了子图设计中的子图。结果表明，灌溉源对生长参数，蛋白质百分比，脂肪酸度，冠层温度和谷物产量没有显着影响。但是，运河和经过处理的污水在光合作用和叶绿素含量方面存在显着差异。此外，数据表明，不同生育水平显著差异（P  ≤0.05）。与对照相比，施用100％RDF，50％和75％RDF可以记录到较高的叶片水势，冠层温度，光合作用和叶绿素含量。随着FYM施用量的增加，重金属（Pb，Cd，Ni和Co）的浓度从2.5 tha ^-1降低到5 tha ^-1在植物中，而在土壤中，随着FYM施用量的增加，这些含量也增加。交互作用对珍珠谷的合并谷粒产量表现出显着影响。与灌溉源无关，将100％RDF与FYM @ 5.0 t / ha一起施用可产生高于75％RDF + FYM @ 5.0 tha ^-1和50％RDF + FYM @ 5.0 tha ^-1的更高产量。这清楚地表明，FYM的更高应用减少了用处理过的污水灌溉的珍珠粟中重金属的积累。
