Response Of Maize To Organic And Mineral Fertilizer In Iraq Conditions

Abstract

To evaluate of efficiency mineral NPK organic fertilizer on productivity of maize , the mineral 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 rates (0,5and 10 megagram.ha-1) and give symbols ( OM0,OM1and OM2) ,the experiment was carried applied in Alanbar province of Iraq and (RCBD) design with factorial arrangement and three replicates was used . Statistical analysis of data had significant effects under this study. Some of traits in indvidual of Plant was studied such as ; height (cm) , NO. of leaves per plant, leaf area (cm), chlorophyll
content(mg.kg-1 ), total dry matter(mega gram. ha-1 ) and percent of protein in the grain .the M4×OM3 scored highest plant ( 199.0 cm ), and (180.310 cm) at two season respectively. While M4 with OM1, MO2 and MO3 scored ( 63.01 , 64.01 dccm2 ),( 64.02, 65.10 dccm2 ) and ( 67.05 , 65.21 dccm2) under two seasons sequentially. Moreover, the M4×OM3 scored (64.53 mg.kg-1 ) and (65.21 mg.kg-1 ), sequentially.In addition to, the M4×OM(2) scored the highest value of total dry matter ( 11.60 mega-gram .ha-1 ) and ( 11.70 mega-gram .ha-1 ) under two season . Finally, the organic fertilizer (OM) and mineral fertilizer (M) caused increased of protein in the grain of maize via scored highest value (9.713 and 9.757 %) at two seasons, respectively .we conclude that the increasing of organic fertilizers and mineral fertilizers caused improved of plant traits .
