Figure 3

Principal Component Analysis (PCA) of yield attributes, nutrient efficiency, SAR, enrichment factor (EF) and Pollution load index (PLI) during and after tomato cultivation. [(A) PCA of the variables showing their major contribution, (B) PCA-Biplot analysis representing the clustering of ground water and different stages of textile dyeing waste water towards major contribution. [UE = use efficiency, SAR = sodium absorption ratio, T1 = Ground water (control), T2 = 2nd wash after scouring and bleaching, T3 = Enzyme treated water, T4 = 2nd wash after bath drain, T5 = Neutralization treatment, T6 = 2nd wash after soaping, T7 = Fixing treatment water, T8 = Mixed effluent].
