   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.

   Field experiment was carried out during spring season of 2017 in the field of Agricultural Collage- University of Baghdad/ Al - Jadriya., Iraq in silt loam calcareous soil to study the effect of micronutrients and water amount applied to intercropped Cucurbita pepo and Cucumis sativus on yield and water use efficiency. Cucurbita pepo (Pumpkin) (synthetic cv. US, Agriseed, Fadwa) andCucumis sativus(cucumber) (synthetic cv. Kazear) were planted monocropping and a strip intercropped. The experiment was a Split Plot Design arranged in RCBD with three replications. micronutrients treatment represents the main plot and intercropping system treatment as sub plot. Micronutrients treatments included application of 3 rates 0, 150 and 250 g 1000 m^-2. Monocropping for Pumpkin and cucumber were planted one line in treatments unit, while Intercropping for Pumpkin and cucumber were planted two line for any one in treatment units. All plots were irrigated with river water (ECi =1.45 dS m^-1), and irrigation was imposed at 35% depletion of available water using drip irrigation system.
  Results indicated that number of irrigations were 40,41 and 39 for monocropping of Cucurbita pepo, Cucumis sativus and intercropping irrigation systems consuming 410 and 425 and 440 mm for the three treatments, respectively. All growth and yield arameters were no significantly at or/and at monocropping compared to intercropping. The interactions effect between the amount of micronutrient and water on fruits yield indicated that the best two treatments were 250 g 1000 m^-2 with mono or /and intercropping (the best overall treatment and no significant with 150g1000m^-2 ), and Values of IWUE for intercropping are almost more than monocropping.
