Results
Comparison of the effects of seed treatment variants on rice production revealed that CA treatment
significant reduced the seedling emergence and establishment under field conditions (Table 1). This result was
significant different from CO, CL and E+CL treatments. CL and E+CL led to higher seedling emergence under
field conditions. However, these results were non-significant different from the control plot. As shown in Table 6.2,
at 2 weeks after sowing, the CA treatment significantly decreased seedling dry weight, shoot and root dry weight
when compared with the biological seed coating substances. CL and E+CL improved the seedling establishment.
