A field experiment in collaboration with a private textile industry (Noor Fatima Fabrics Private (Ltd.), Faisalabad) was conducted to evaluate the effect of disposed water from bleaching unit, printing unit and end drain for improving growth and yield of wheat under saline sodic soil. Textile waste water along with canal water (control) was applied with and without liquid NPK fertilizer. The application of liquid NPK fertilizer with end drain waste water increased plant height, spike length, flag leaf length, root length, number of tillers (m(-2)), number of fertile tillers (m(-2)), 1000 grain weight, grain yield, straw yield and biological yield up to 21, 20, 20, 44, 17, 20, 14, 44, 40 and 41%, respectively compared to canal water (control). Similarly, the NPK uptake in grain was increased up to 15, 30 and 28%, respectively by liquid fertilizer treated end drain water as compare to canal water with liquid fertilizer. Moreover, concentration of different heavy metals particularly Cu, Cr, Pb and Cd was decreased in grains by application of waste water along with liquid NPK. The result may imply that waste water application along with liquid-NPK could be a novel approach for improving growth and yield of wheat in saline sodic soils.
与一家私营纺织企业（费萨拉巴德努尔·法蒂玛织物私人有限公司）合作开展了一项田间试验，以评估漂白车间、印花车间排放的废水以及终端排水对盐碱土壤中小麦生长和产量的影响。纺织废水与运河水（对照）分别在施用和不施用液体氮磷钾肥料的情况下进行灌溉。与运河水（对照）相比，施用液体氮磷钾肥料的终端排水使株高、穗长、旗叶长、根长、分蘖数（每平方米）、有效分蘖数（每平方米）、千粒重、籽粒产量、秸秆产量和生物产量分别提高了21%、20%、20%、44%、17%、20%、14%、44%、40%和41%。同样，与施用液体肥料的运河水相比，经液体肥料处理的终端排水使籽粒中的氮磷钾吸收量分别提高了15%、30%和28%。此外，施用废水和液体氮磷钾肥料可降低籽粒中不同重金属特别是铜、铬、铅和镉的浓度。结果可能表明，废水与液体氮磷钾一起施用可能是提高盐碱土壤中小麦生长和产量的一种新方法。
