Phosphorus (P) content of soil after harvesting
as affected by applying different methods of Zn
are presented in Table 5. The application of
different methods Zn application, content in soil
decreased P significantly compared with no Zn.
The highest P content observed in T1, however
no significant differences were recorded among
the methods of Zn application. Phosphorus
interacts with Zn in soil which reduces Zn
translocation from roots to the shoots [51] and
also imbalanced P: Zn ratio in plant (dilution
effect) has a negative effect on rice yield. Other
studies also indicated that P application
influenced Zn uptake by rice and translocation
into shoots [52].
The content of total K percentage of soil at
harvesting time as affected by different of
methods Zn application are presented in Table 5.
The results indicated that the application of
different of methods Zn application has a little
effect of increase the total N percentage
compared with no Zn added (control). The
highest total N percentage of 0.19% was
recorded with T4, followed by T3 and T2. Similar
results have been reported [52].
