Experiment was conducted during the growing season of summer 2014 in a rice field at Al-Hira district in the province of Najaf to examine two factors, water type (magnetized MW and regular RW) and herbicide (Nominee and Rainbow at full and half of the recommended dose) and their effects on rice growth parameters including plant height, number of branches, fresh and dry weight. The experiment was two factorial base on Randomized Completely Block Design (RCBD) with three replicates. Results showed significant differences among all treatments in the experiment. The MW treatment significantly resulted in higher values of all parameters tested compared to the RW and weedy treatments, respectively. However, values of tested plant parameters were higher in both herbicides treatments with no significance compared to those of the MW treatment but at the same time were significantly much higher where compared to other treatments. Comparison between the herbicides showed that Nominee resulted in higher, but not significant, growth parameters compared those of the herbicide Rainbow. While, interaction among all treatments showed that the best results were from MW interacted with Nominee over other interaction treatments. Magnetized water in this study was approver to be effective treatment in supporting all growth parameters in rice crop fields.

This research was conducted in unheated plastic house at Horticulture and Landscape Design Department, College of Agriculture & Forestry, Mosul University, during the growing season 2012-2013. The aim of this study was to investigate the effect of magnetic water and urea spray on the yield of two lettuce cultivars in NFT culture system, transplants of two lettuce varieties (Regina dei ghiacci and Great Lakes 118) were continuously treated by three intensities of magnetic water (0 ,750 and 1500 gauss) during the experiment period and two foliar sprays of pure urea at three concentrators (0, 0.125 and 0.250 %) were applid.
 
Asplit-split plot system within a randomize complete block design (RCBD) with three replicates was used to carry out this experiment. Results data could be summarized as follows the Regina dei ghiacci variety has been significantly superior in the percentage protein .
 
with Great Lakes 118 variety. while the Great Lakes 118 variety was significantly  superior  in percentage of the percentage leaf chlorophyll content. All urea treatments  caused a significant increase all lettuce parameters as compared with control treatment.
 
Using magnetic water at 750 gauss intensities caused a significant increasment in most yield parameters as compared with control treatment. Mean while Generally, the interaction treatments caused extra effect on vegetative characteristics as compared with the effect of each single factor.

magnetized water(MW), the fungus Aspergillus spp. the herbicide Granestar on wheat growth. In a preliminary experiment, magnetized water at three magnetic density levels (1600, 3200, 4800) Gauss was tested to determine the better intensity for seed germination and plant growth of wheat and the wild radish weed. The aim of the study was to control the wild radish in the wheat fields by developing an integrated program to reduce the use of chemical pesticides by using environmentally friendly agents including the bio-agent fungus Aspergillus spp., magnetized water as a physical agent and the Granstar herbicide.




solani and Aspergillus spp. were isolated from wheat and wild radish seedlings and pathogenically tested on both host plants. Results showed that both R. solani and Aspergillus sp. increased germination and seedlings growth of the wheat and inhibited germination and growth of the wild radish. Aspergillus spp. had no negative effects on seed germination and seedlings growth where tested on different plant families seeds including cow pea, cucumber, radish, barley, melon, garden cress and green mung beans.




      Seed germination percentage and seedlings length of wheat and wild radish were affected by magnetic intensity levels after 21 days of planting. The 1600 G was the best treatment for seed germination and seedlings length of wheat, and at the same time this intensity level  negatively affected the wild radish seeds and seedlings resulted in the lowest values of  germination and seedlings length. However, the highest intensity level 4800 G  did support highest seed germination percentage and seedlings length of the wild radish, but this intensity had negative effects on wheat seeds germination and seedlings length. 
 
     The main field experiment was conducted during the winter growing season of 2016 in one of Al-Hirah wheat field  in the province of Najaf. The experiment was factorial with two factors, MW as main factor and the fungus Aspergillus spp. and the herbicide Granstar at half and full of recommended dose based on RCBD design with three replicates.
 
    The treatment of MW (1600 G) significantly increased all plant growth parameters tested (Weight of spike, weight of 1000 seeds, and total yield) compared to the control (RW). All treatments combinations that included the bio-agent Aspergillus spp. Resulted in enhancing all growth and yield parameters tested with total yield of 5.505 ton.h-1 compared to 2.778 ton.h-1from the plants not treated with the fungus.
