Evaluation of some morphological and physiological characteristics of cumin by using of magnetic water and superabsorbent under low irrigation regime
In order to investigate magnetic and superabsorbent water on some morphophysiological traits and yield of cumin (Cuminum cyminum L.) under low irrigation regime, an experiment was conducted in research farms under the supervision of Shahroud University of Technology Faculty of Agriculture in Rahnjan and German districts of Shahroud city. It was done in a randomized complete block design with three replications.Irrigation water (normal and magnetic) and location (Rahanjan, German) was considered as the main factor and superabsorbent treatment (0, 100 and 200 kg / ha) was considered as a secondary factor.In all treatments, irrigation was applied based on 50% of plant water requirement. The results showed that location, type of irrigation and different concentrations of superabsorbent had a significant effect on the growth and physiological characteristics of cumin.The highest plant height, fresh and dry weight of the plant was observed in Rahanjan area using a superabsorbent concentration of 100 kg / ha. Due to climatic conditions and higher annual average temperature and treatment of 100 and 200 kg per hectare of superabsorbent and work on magnetic water, the highest amount of plant height, percentage of essential oil and protein, and soluble carbohydrates were observed. According to the results, most of the traits in Rahanjan region had higher values than German region. And plant cultivation in Rahnjan region is economic.
