Effect Of Different Rates Of NPK And Vermicompost On Some Traits Of Maize

Abstract

To evaluate of efficiency mineral NPK  organic fertilizer on productivity of maize  , the NPK fertilizers were supplied as rate  ( 0 , 25, 50 and 100 % from recommendation ) and give symbols (M1,M2,M3 and M4) .While , the  organic fertilizers were supplied  as levels  (0,5and 10 megagram.ha^-1) and the treatments were symbols as  ( OM0,OM1and OM2) , a field experiment was  applied in the Alanbar province of Iraq  by using  design (RCBD) design with factorial arrangement and three replicates.The data  analysis  were shows a  significant effects under this study.  Concentration of Nitrogen per leaf  ,  concentration of phosphorus per leaf,   concentration of potassium per leaf  , ear lenghth,  number of kernels (mega gram. ha^-1 ) and   yield ton per ha^-1  .  the M4×OM3 scored highest plant (1.243 mg .kg^-1  )  and (1.29 mg.kg^-1   ) at two season  Sequentially . While M4 with OM1, MO2 and MO3 scored of phosphorus concentration  (  0.30 mg.kg^-1  ) و,and ( 0.29  mg.kg^-1  )  under  two seasons respectively. Moreover, the M4×OM3 scored to potassium level (20.46   mg.kg^-1 ) and   (20.23   mg.kg^-1 ), respectively .In addition to, the  M4×OM(2) recorded the highest value  of kernel weight (150.66   gm of 500 kernels  ) and ( 154.33 gm of 500 kernels) under two season . Finally, the organic fertilizer (OM) and mineral fertilizer (M) caused increased of   yield of maize and scored highest value (150  and 152 gm per plant )  at two seasons, respectively .we conclude that the increasing of organic fertilizers and mineral fertilizers caused improved of  plant traits.
