Zinc (Zn) and
manganese (Mn) are important micronutrients in plant growth and development. In
this study, the effect of Zn and Mn sulfate treatments at different growth
stages of mother plants in common bean on seed production and germination
potential was carried out. Results showed that zinc sulfate (ZnSo4) treatments
significantly affected yield and pod number per plant compared to manganese
sulfate tetrahydrate (MnSO4) treatments. Treatment in any form or at any stage
of growth increased yield and its components in common bean. The highest
efficiency of ZnSO4 was obtained in the pod production stage; MnSO4 enjoyed
greater efficiency in the flowering stage; and the minimum efficiency was
observed for soil application. The zinc and manganese content in the seed
production by foliar application in the stem elongation + flowering + pod
production stages were the highest. The two-year performance increase for
three-stage consumption of zinc sulfate in comparison to no-consumption and
soil consumption was respectively 173 and 202 g/m2; by using manganese sulfate,
the consumption was 92 and 134 g/m2. This increased yield seems economical
compared with the costs incurred in the preparation and consumption of it. The
increase in seed quality due to the increasing content of micronutrients, especially
zinc, was noticeable. The results of the germination experiment showed that the
plant dry weight and germination percentage treated with ZnSO4 in the lab were
significantly higher than MnSO4. In the treatments by foliar application, the
plant height was related to the seeds treated with Zn fertilizer, but in soil
treatments, the use or nonuse of Mn fertilizer caused higher plant height. The seed
production from the treated crops with foliar application at flowering + stem
elongation germination was faster than the other treatments, but the minimum
rate was obtained for the control group. The result showed that Zn and
Mn-sprayed seeds had a significant impact on the vigor of the seedlings.
