The study was carried out to evaluate the effects of magnetic water, organic and chemical fertilizers on growth characteristics and yield of Moldavian balm (Dracocephalum moldavica L.).

This experiment was conducted as a factorial based on a randomized complete block design with 21 treatments and three replications at research farm of the faculty of agriculture, university of Tabriz, Iran in 2016.The first factor was magnetic water (0, 290, and 430 milli Tesla) and the second factor was fertilizer treatment (control, 100% chemical fertilizers+NPK fertilizer, 50% chemical fertilizer+bio-fertilizer, Penergetic P, 50% chemical fertilizer+Penergetic P, 50% chemical fertilizer +organic wood fertilizer with 2 and 4 tons/ha).

Increasing the intensity of the magnetic improved the transverse growth of the plant, leaf chlorophyll index, dry weight of upper flowering parts, and essential oil yield of Moldavian balm. The interaction effect of magnetic water fertilizer treatments was significant on number of branch per plant, dry weight of upper parts, essential oil percentage and yield. The highest dry weight of upper flowering parts (7668.70 kg/ha) was obtained in 100% chemical fertilizer and magnetic water of 430 milliTesla. The highest essential oil yield (16.59 kg/ha) was obtained in organic wood fertilizer in 2 tons ha and without using magnetic water.

Bio-fertilizer and organic fertilizers in combination with 50% of chemical fertilizers coupled with magnetic water of 430 milliTesla could be recommended to improve the growth traits, qualitative and quantitative yield of Moldavian balm in the field condition.

The goals of study were to evaluate of Alfalfa traits by using penergetic P and K under free and infested by Dodder (Cuscuta campestris).

The greenhouse experiment was conducted at the Faculty of Agriculture, University of Tabriz in 2017. The experimental design was a completely randomized design with 8 treatments and two replications. Treatments were penergetic P+dodder infested , penergetic K+dodder infested, penergetic water+dodder infested, control+dodder infested, penergetic P+dodder free, penergetic K+dodder free, penergetic water+dodder free and control+dodder free.

Different treatments of penergetic had significant effect on plant height, number of sub stem per plant, diameter of main stem, fresh weight, number of leaves per plant, chlorophyll index and alfalfa biomass. The highest plant height with 49.18cm was achieved by penergetic water + dodder free and the highest chlorophyll index under penergetic P + dodder infested. The highest biomass yield was obtained from penergetic P+ dodder free treatment and the lowest biomass yield was observed in control+dodder infested treatment.

It can be concluded that using of different treatments of penergetic in the recommended doses increase the alfalfa resistance to dodder.

This study was conducted to investigate the effect of water (irrigation with ordinary water and magnetic water) and fertilizer treatments on cumin growth and yield by split plot experiment based on randomized complete block design in three replications at the Research Farm of Tabriz Branch Islamic Azad University, Tabriz, Iran, in 2018. Treatments included control without fertilizer, application of nitrogen fertilizer, application of Penergetic fertilizer P, K and application of nitrogen fertilizer with 50% dose with use of Penergetic P, K. Results showed that, the highest grain yield (164 g.m-2) was obtained in nitrogen fertilizer application and application of chemical fertilizer and Penergetic P, K under magnetic irrigation conditions. This treatments increased grain yield in comparison with control (42.6%). Biological yield also showed a similar response to the application of magnetic irrigation and fertilizer treatments. Based on the results of two treatments, application of nitrogen fertilizer alone and nitrogen fertilizer with Penergetic P, K produced a significant increase in essential oil percentage, but the highest essential oil yield was obtained from application of chemical fertilizer (3.13 g.m-2) however, application of Penergetic fertilizer caused a significant increase in the percentage and essential oil yield, although less than the increase caused by nitrogen fertilizer. In general, with respect to economic performance, using Penergetic, the level of nitrogen fertilizer can be reduced without any significant reduction in grain yield. On the other hand, magnetic irrigation has an important role in increasing the effect of application of fertilizers on grain yield.
