Abstract

Drought is one of the most important abiotic stresses in Iran’s agriculture and annually causes many damages to plant productions. This study was designed to determine effect of water-superabsorbent polymer and drought on seedling establishment and growth in some warm season plants (foxtail millet, dill and fenugreek). This experiment was conducted as a pot experiment at Campus of Agriculture and Natural Resources, Razi University. In the pot experiment, effect of water-superabsornbent polymer (0, 0.02, 0.04 and 0.08 grams per kilogram of soil) and drought (favorable and long-term irrigation) on warm season plants were investigated. Results showed that by increasing water-superabsorbent polymer application, seedling fresh weight, seedling dry weight, seedling height, emergence percentage and rate were increased. Drought reduced mentioned traits, but water-superabsorbent was able to reduce drought negative effects partially. Regarding results, for high emergence in foxtail millet, fenugreek and dill, application of 0.08 g of superabsorbent per kilogram of soil is usefull, especially under drought condition.
