بررسی شوری آب آبیاری و کودهای مختلف بر واکنش فیزیولوژیکی و فعالیت آنزیم‌های آنتی‌اکسیدانی ریشه زیره سبز (Cuminum cyminum L.)

To evaluate the effects of water irrigation quality with individual and combined treatments of chemical fertilizer, manure and control on cumin, a split-plot experiment in randomized complete block design with three replications was conducted at the Research Farm of Zabol University during 2012. The result indicated that increasing Electrical Conductivity of water irrigations quality to range of 4.180 dS.m-1 lead to decrease of root length, fresh weight, dry weight of root and phosphorus content; Whereas the activities of CAT, APX, GPX enzymes and sodium content in root tissues increased. Consumption of fertilizers Compared with non-fertilizer was more effectual in improving studied characters, among used different fertilizers, was obtained more definitive effect from compilation of fertilization systems due to synergy effects of fertilizers. According to the results of this field study, the use of organic materials in agricultural fields will reduce the need to use chemical fertilizers; so in order to reduce using of chemical fertilizers as well as unilateral and required elements need of plant in salt stress conditions, consumption of NPK fertilizer with 40:20:15 kg.ha-1 ratio with 20 ton.ha-1 manure in area is recommended.
