Mr Zuma has been dogged by allegations of corruption and cronyism and widely criticised for his handling of the economy.
Previous addresses by him have been marred by MPs demanding his resignation.
As Mr Zuma entered parliament in Cape Town on Thursday (local time) he was met by chants of "thief" by EFF MPs, who included their leader Julius Malema.
Members of the governing African National Congress (ANC) countered them by chanting "ANC, ANC".
Amid raised voices and chaotic scenes, Speaker Baleka Mbete tried to deal with repeated interruptions and procedural questions.
Mr Malema called Mr Zuma "an incorrigible man rotten to the core".
He also turned on the speaker, telling her: "Your conduct has failed you. You are irrational, impatient, partisan."
Ms Mbete told the protesting MPs: "We have been patient with you, we have been trying to give you an opportunity to express yourselves but ... it is being abused."
Security guards were called in and the EFF members were forcibly ejected. Members of another opposition party, the Democratic Alliance, then walked out, and said President Zuma was unqualified to hold office.

A smiling President Zuma said "finally" as he resumed his address, speaking about the economy and other issues.
Mr Zuma had angered some MPs ahead of his speech by ordering the deployment of about 440 troops to maintain law and order in parliament on the day.
Opposition parties condemned the decision as a "declaration of war".
It was the first time that troops had a security rather than a ceremonial role.
Previous State of the Nation speeches have been marred by chaos in parliament.
Since winning seats in 2014, members of the EFF have caused disruption by chanting and jeering at the president over allegations of corruption.
In 2015, EFF members were removed from the chamber by security guards disguised as waiters.
