The effect of different concentrations of foliar application of NBS on leaf pigments (a) chlorophyll a, (b) chlorophyll b, (c) total chlorophyll and (d) carotenoid contents in leaves of tomato under salinity. Mean values are the average of three replicates. The upper case alphabetic letters indicate significant differences (P ≤ 0.05) among treatments using Tukey’s test.
