Table 9.

Potassium fertilization schedule during the experiment.

Treatments Description Potassium fertilization schedule (muriate of potash; 60% K2O)
80CF Control flooding + 80 kgK2O/ha (Control) 80 kg K2O/ha fertilization split into two phases:

  1. 30% – 3 leaves stage (15 DAS 1)

  2. 70% – booting 2 (50–55 DAS)
120PW15 Periodical water stress for 15 days + 120 kg K2O/ha 120 kg K2O/ha fertilization split into three phases:

  1. 30% – 3 leaves stage (15 DAS)

  2. 30% – booting stage (50–55 DAS)

  3. 40% – (80–90 DAS during water stress cycle)
120DS15V Drought stress 15 days at the vegetative stage + 120 kg K2O/ha 120 kg K2O/ha fertilization split into two phases:

  1. 30% – 3 leaves stage (15 DAS)

  2. 70% – booting stage (50–55 DAS)
120DS25V Drought stress for 25 days at the vegetative stage + 120 kg K2O/ha 120 kg K2O/ha fertilization split into two phases:

  1. 30% – 3 leaves stage (15 DAS)

  2. 70% – booting stage (50–55 DAS)
120DS15R Drought stress for 15 days at the reproductive stage + 120 kg K2O/ha 120 kg K2O/ha fertilization split into two phases:

  1. 30% – 3 leaves stage (15 DAS) 36 kg/ha

  2. 70% – booting stage (50–55 DAS)

1 DAS = day after sowing; 2 booting = bulging of young panicle inside the flag leaf sheath.
