Abstract

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. ) . ) .

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
