The effect of spray iron and zinc in some recipes growth and holds wheat research - 7

Abstract

To study the effect of spraying ferrous and zinc sulfates on some of vegetativeproperties and yield of grain of wheat buhooth -7 .Factorial experiment wasconducted at Field of crop production sciences . College of Agriculture –university of Baghdad . Requirements of N, P and K Fertilizers were added,three concentrations of Fe (0,50.100 ) mg.L-1 and three concentrations of Zn(0,50.100 ) mg.L-1 were sprayed at three stages of wheat growth ( vegetativegrowth , boating and Flowering stages of crop growth ) . Randomized completeblock design was used at three replicated . Results showed that :All concentrations of Fe , Zn and their interactions were significantly affectedon all plant parameters under study . High values were produced of interactions ofFe 2 × Zn 2 which were : 122.5 cm , 43.2 cm 2 , 9 filler per plant , 50.2 spad unitand 5.88 t.ha-1 for plant height , flag leaf area , tiller per plant , chlorophyll indexand yield of grains respectively .
