An investigation on possible effect of leaching fractions physiological responses of hot pepper plants to irrigation water salinity

Table 3 Carbon isotope discriminaion (Δ¹³C, ‰), C content (% DW), total C accumulation (g plant^− 1), nitrogen isotope composition (δ¹⁵N, ‰) and total N accumulation (g plant^− 1) in hot pepper leaves as affected by varying levels of irrigation water salinity (EC_iw, dS m^− 1) and two leaching fractions (LF). The values for each treatment measured at the end of the experiment were the averages of four replications
