Evaluation of Some Morphological and Physiological Characteristics of ‎Cumin by Using Magnetic Water and Superabsorbent under a Low Irrigation Regime

The effect of magnetic and superabsorbent water was investigated on some morphophysiological traits and performance of cumin under a low irrigation regime.

An experiment was conducted in the agricultural year of 1399-1400 in the research fields of the Faculty of Agriculture of Shahrood University of Technology in two districts of Rahnjan and Garman of Shahrood city in a factorial format in the form of a randomized complete block design with three repetitions. Irrigation water type treatment at two levels (normal and magnetic) and locations (Rahanjan, Garman) with different climatic conditions and altitude above sea level as the main factor and superabsorbent treatment at three levels (zero, 100 and 200 kg/ha) as a secondary factor. Was considered. In all treatments, irrigation was applied based on 100% of plant water needs.

The results showed location, type of irrigation and different concentrations of superabsorbent had a positive and significant effect on the growth characteristics. In the Rahnjan region, due to the climatic conditions and higher average annual temperature and the treatment of 100 and 200 kg/ha of superabsorbent and the use of magnetic water, the highest amount of plant height, percentage and yield of essential oil and protein, soluble carbohydrates were observed.

According to the results, most of the traits in the Rahnjan region had higher values than in the German region, and plant cultivation in the Rahnjan region is economical.
