A field experiment is conducted in Al – Najaf Governorate during summer season 2015 to study the effects of magnetic water irrigation and Zinc foliar applications on Zinc concentration in grain , yield and growth of rice (Oriza sativa L.) of Yasmin variety . Treatments include using zinc ( ZnSo4.7H2O ( 23 % ZN ) with three levels (0 , 75 , 150) mg.zn.L-1 and tow levels of magnetic water irrigation ( magnetic 3500 gauss and no treatment ) Split plot according to RCBD with three replicates is designed . The following results are obtained :
1- The levels of magnetic water irrigation have significant effect on zinc concentration 32.6 mg . kg-1 grain , straw yield 9.75 mega gm. h-1 , plant height 116 cm , length of spikelet 27.03 cm, no. of seed in spikelet 130 seeds , wt. of 1000 grain ( 20gm ) .
2- There is a significant effect of the level of foliar Zinc on % fertility 17.75 % , grain yield 6.14 mega gm.h-1 ,zinc concentration 32.7 mg . kg-1 grain , no. of spikelet 409.3 .m-2 , straw yield straw yield 9.72 mega gm. h-1 , plant height 116 cm , length of spikelet 26.9 cm.
3 - The interaction between magnetic water & levels of Zinc application affects significantly in the grain yield 6.77 mega gm.h-1 , straw yield 10.28 mega gm. h-1 and zinc concentration in grain 35.3 mg Zn.kg-1 grain , plant height 119 cm , length of spikelet 28.7 , no. of seed in spikelet (143 seeds) , weight of 1000 grain ( 20.6 gm. ) .

A field experiment is carried out in one of the farmers' fields in the north-east of Ramadi District area in Anbar Province during growth season 2012 -2013 in a Silty Loam texture soil, to study the effect of time and the level of agricultural sulfur application on the uptake of ( phosphorus, iron, Zinc ) in plant and the growth of two genotypes of maize plant Zea mays L. (genotypes 5012 and genotypes 106). The agricultural sulfur produced locally in Mishraq fields (95% S) in two levels ( 0 , 2500 ) Kg.ha-1 on fure time ( applied when agriculture, applied a month later of planting, applied two months later of planting, applied three months of planting) , nitrogen is at a rate of 320 kg.ha-1 using urea (46% N) phosphorus is added at a rate of 100 kg P.ha-1 using the fertilizer DAP (21% P) and potassium is added at a rate of 180 kg K.ha-1 using potassium sulfate (41.5 % K) , according to a global experience within the randomized complete block design (RCBD) and three replicates.
The results show a significant increase in genotypes 106 other than genotypes 5012 in the uptake of (phosphorus, iron and zinc)and in the plant and (dry weight of shoots, the number of grains per head and yield) when agricultural sulfur is applied to the soil, and treatment of agricultural sulfur two months later of planting (T3) also give a significant increase in indicators as compared to treatment (T1), which give the lowest values, the treatment of agricultural sulfur application is higher than control where it gave the highest average of grain yield to 6.15 T.ha-1,in an increase of 23.74% compared with the control treatment, application of agricultural sulfur gave a significant effect on grain yield as T3 treatment achieved a higher yield of 6.63 T.ha-1 in an increase of 17.13% as compared with treatment T1, which give less yield of grain of 5.66 T.ha-1.
