| 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. ) . ) . | ||
