   Field experiment was conducted in An-Najaf governorate during of 2016 in two season spring and autumn. The aim of this experiment was to study the effect of hornwort extractions and magnetically treated water on growth and yield parameters in cucumber plant beta alfa variety
 
         The experiment included nine treatments, i.e. the interactions of  three concentrations  of hornwort extractions (first factor)(0, 10 and 20ml.L-1)sprayed on vegetative and magnetically treated water(second factor) (0, 1000 and 2000 gauss).Sprays were applied third, first sprayed through four true leaves stages, second flowering initiation, third after two weeks from second sprayed.
 
Split-Plot Design with in Randomized Complete Block Design (R. C. B. D.)  was used with three replications. magnetically treated water treatments was distributed in main plots and hornwort extractions treatments in sub plot , Means were compared according to Duncan's Multiple Range Test (D.M.R.T.) at probability of 0.05.
 
     Results can be summarized as follows:.
 
1- Using of concentrations  of hornwort extractions had a significant effect on measured vegetative growth parameters (plant length, leaves number). There was no significant effect between 10 and 20ml.L-1in plant length parameter. There was no significant effect between1000 and 2000 gauss in plant length for two season and leaves number in spring cultivation. interaction between factors gave the same trends on vegetative growth parameters.
 
2- Using of concentrations  of hornwort extractions had a significant effect on fruit growth parameters 20ml.L-1treatment gave the highest means for the fruit length and total yield (53.08 and 39.55ton.h-1)  compared with control gave the lowest means for the measured parameters for both season. There was no significant effect between 10 and 20ml.L-1 in fruit length parameter in spring cultivation,2000 gauss treatment gave the highest means in total yield(48.51 ton.h-1) in spring cultivation while1000 gauss treatment gave the highest means in total yield(35.70 ton.h-1) in autumn cultivation, 1000 and 2000 gauss don’t gave a significant effect in total yield for both season.1000 and 2000 gauss don’t gave a significant effect in fruit length for both season.
 
3-Spraying  of hornwort extraction as conc. 20ml.L-1 had a significant effect on measured chemical parameters such, total chlorophyll for both season, respectively, while proline in leaves which gave the least values with the use of hornwort extraction.
 
         Irrigation with 2000 gauss treatment  gave the highest means for the, total chlorophyll for both season, while  proline in leaves which gave the least values with the use of magnetically treated water. There was no significant effect between 1000 and 2000 gauss in total chlorophyll content for both season and proline in leaves in the Spring cultivation.

 An experiment was conducted in the collage of Agriculture ,University of kufa , during the growing season of 20016-2017 to study the effects of irrigation with magnetized water(MW) at density level of 1600 gauss, the fungus Aspergillus and the herbicide Granstar (at 50% and 100% of the recommended dose) on wheat growth parameters and yield. Results showed that Aspergillus spp interacted with MW  significantly resulted in the highest values of NPK content and yield compared to the lowest values from the Granstar and weedy control treatments with and without MW, respectively. On the other hand, irrigation with MW always resulted in higher values of tested parameters than that those irrigated with regular water, all treatments interacted with MW had better and higher effects compared to of those interacted with regular water. The study showed that using the bio-controlling agent Aspergillius spp decreased weed and increased wheat growth. and using magnetized water is useful for better growth parameters and yield in wheat fields.
