EFFECT OF SEED COATING WITH SOME MICRONUTRIENTS ON FABA BEAN (Vicia faba L.) I- EFFECT ON PHOTOSYNTHETIC PIGMENTS, MICRONUTRIENTS CONTENT AND PLANT GROWTH CHARACTERS
Two field experiments were carried out at the farm of El-Gemmeiza Agric.Res. Station, Agric.Res. Center, during the two successive growing seasons; 1998/99 and 1999/2000 to study the effect of Zn, Mn and Fe on plant growth, photosynthetic pigments and some micronutrients content of faba bean leaves at 70 days age. Zn, Mn and Fe were added by seed coating method at a rate of 0.3gm of Zn or Fe and 0.15 gm of Mn in chelating form per one kilogram seed, individually or in all possible combination. Yet, the relations between the content of photosynthetic pigments and micronutrients in leaves were considered.
The mean results of the two growing seasons showed that plant height, number of both leaves and branches as well as dry matter of various organs seemed to be improved by the different treatments. Moreover, photosynthetic pigments and micronutrients content in leaves were also significantly increased as a result of micronutrients application. In this respect, addition of Zn,Mn and Fe simultaneously induced the highest values for all aforementioned parameters followed by the dual combinations, whereas the individual treatments recorded the least increments compared with the control treatment.
On the other hand, photosynthetic pigments in faba bean leaves were positively correlated by micronutrients content at different treatments of micronutrients as the following descending order: Mn< Zn < Fe.
The aforesaid relations can be expressed as the following multiple equations:
Y1 = 3.37 + 38.18X1** + 28.42X2** + 1.63X3** (r2 = 0.999)
Y2 = 1.61 + 3.82X1** + 17.35X2 + 1.21X3* (r2 = 0.989)
Where; Y1, Y2, X1, X2 and X3 indicate the mean values of Chl.(a+b), carotene, Zn,Mn and Fe content in leaves, respectively in (mg/plant).
* significant at 0.05 level ** significant at 0.01 level
