| Abstract | ||
| A Field experiment had been performed in Shewn Research Station of the Agriculture Department in Kirkuk province during the summer season (2015). The study aimied at to study the effect of humic acid and spraying iron, zinc and as well as the overlap between them in growth traits of Datura stramonium L. The experiment had included two factors. The first factor includes four levels of humic acid (0, 1, 2 and 3) kg. Acres -1 The second factor included four concentrations of spraying elements (Fe ppm250 and Zn ppm250 and Fe + Zn ppm250 and 0). The Experiment applies global testing system according to the design of complete random sectors design with three replicates . Results can be summarized as follows. . The level of acid humic was Higher 3 Cgm.dunm - in all vegetative growth traits ,such as plant height (104.49 cm.nbat -1) , the number of branches (10.46per plant) dry matter (456.79 Gm.) hunmic acid shows significant superior rates in corp. traits and yield components like the number of fruits (49.798 Tmrh.nbat -1) per plant weight of 1000 grains (12.69 g) and corp (541.06 Cgm.hectar -1). The concentration of spraying exceeds((Fe + Zn ppm 250 in all growth traits such as high plant vegetative growth (119.36 cm per plant) , the number of branches (13.11) ,dry weight (577.92 gm) The concentration gave ((Fe + Zn ppm 250) and is high as the number of fruits (62.853 Tmrh.nbat -1) and the weight of 1000 grains gave higher number(13.93 g) with yield(634.22 Cgm.hectar -1). | ||
