Abstract
Two field experiments were conducted during two successive seasons in the
Nubaria region in Egypt. The soil was supplemented with organic manuras, either
chicken (CKM) or farmyard (FYM). Foiiar application of the cowpea plants with indole
acetic acid (lAA) at three concentrations (12.5. 25 3. 50 ppm) induced increments of the
plants height, fresh and dry weights, number of branches and number of leaves/plant
as well as yield components (podslplant, seedslpod, weight of pod, weight of
seeds/plant and weight of seedsiFeddan). in addition. the same treatments induced a
defense mechanism by increasing the accumulation of organic solutes Such as sugars,
proline and total soluble nitrogen and inorganic solutes (K, Na. Ca. Mg, Zn. Fe and Cu) in
the leaves and seeds. Meanwhile the same treatments induced a reduction in the Mn, Pb
and Ni contents. The effect of organic fertilizers (CKM and FYM) showed a significant
increase in all the mentioned parameters when compared with a control. Meanwhile,
the combination of different concentrations of IAA with organic manure induced a
highly significant increase in all the above mentioned parameters.
