Evaluation of the effects of Seed Priming on Growth properties of Sweet Pepper under Irrigation with Magnetized water.

The increase in population in the country needs to increase the agricultural products. It is necessary to use new techniques to increase performance and make maximum use of available water resources. Priming decreasesthe cultivation period. Therefore, the total water requirement during the growing season will be reduced.The magnetized water has effects on some of the morphological characteristics of the plant, improve them. This study was conducted to investigate the effect of magnetized water and seed priming on growth characteristics of bell pepper in Ferdowsi University of Mashhad. This research was conducted as a factorial experiment in a completely randomized design with five replications and two priming factors with two levels (without priming and hydropriming) and magnetic field intensity with three levels (zero, 0.3 and 0.6 Tesla). The results have been shown that magnetized water was significant at 1% probability level on leaf area, shoot length, fresh and dry weight of shoot but on fresh and dry weight of leaf at 5% probability level Seed hydro priming was also significant on root diameter and stem length at 5% probability level. The interaction effects of treatments were significant on root length, root dry weight at 1% probability level, and on root surface, root volume, root fresh weight at 5% probability level.The use of magnetized water with 0.3 and 0.6 Tesla magnetic intensity increased the leaf area by 13.1% and 20.93%, 13.73% and 15.69% leaf fresh weight, respectively, and the highest stem fresh weight (0.27 g) in magnetizes water as irrigation was 0.6 Tesla and its lowest (0.2 g) was observed in ordinary water treatment. The highest root volume was observed in 0.6 Tesla magnetic intensity and seed hydro priming treatment (0.24 cm3). The highest (0.53 g) root fresh weight was observed in 0.3 Tesla and seed hydro priming and the lowest (0.39 g) in 0.3 Tesla, magnetic intensity, seed treatment without seed priming. As a result, irrigation with magnetized water and seed hydro priming resulted in improvement of morphological properties of bell pepper transplant.
