  To evaluate the effects of quality of irrigation water and kinds of fertilizer on yield and some cumin’s physiological parameters, a split-plot experiment in randomized complete block design with three replications was conducted at the Research Farm of Zabol University. Main factor was two levels of water irrigation, fresh and natural saline water (EC: 4.180 dS.m-1) and the sub-plots consisted of control, NPK fertilizer, manure and their combination. Analysis of plant growth parameters were performed according to the four times samplings. The results indicated that increasing the concentration of soluble salts in water irrigation until 4.180 dS.m-1 resulted in significant decrease in dry matter, biomass duration, crop growth rate, relative growth rate, relative water content of shoots and roots and yield; It was also showed that application NPK-fertilizer at rate 40:20:15 kg.ha-1 combined with manure with 20 ton.ha-1 can improve growth characters, RWC and yield of cumin as compared to the use of fertilizer separately. The highest dry matter (0.544 g. per plant) were obtained from integrated fertilizer and saline water irrigation treatments at 105 days after sowing. It also emphasized that balanced supply organic fertilizers of micro and macro nutrients for plants can reduce application of chemical fertilizer in fields, without reducing of growth characters and yield of cumin.
