Mrs. Indira Gandhi's government implemented several policy initiatives during her tenure as the Prime Minister of India. These initiatives aimed to address various socio-economic issues and strengthen the country's position in the global arena. However, one policy initiative that was not included in her government's agenda was the ban on nuclear tests.

Abolition of Privy Purse:
One of the key policy initiatives of Mrs. Indira Gandhi's government was the abolition of the privy purse. The privy purse was a financial grant given to the former rulers of princely states in India after the integration of these states into the Indian Union. The government believed that this financial support to the erstwhile rulers was an unnecessary burden on the exchequer and decided to abolish it. This decision was aimed at bringing about greater equality and fairness in the distribution of wealth and resources in the country.

Nationalisation of Banks:
Another significant policy initiative undertaken by Mrs. Indira Gandhi's government was the nationalisation of banks. This move was aimed at promoting financial inclusion and reducing the concentration of wealth in the hands of a few individuals and corporations. By nationalising the banks, the government aimed to ensure that banking services were accessible to all sections of society, especially the underprivileged and rural population. This initiative played a crucial role in expanding the reach of banking services and fostering economic development in the country.

Nuclear Tests:
Mrs. Indira Gandhi's government did undertake nuclear tests during her tenure as Prime Minister. In 1974, India conducted its first nuclear test, codenamed "Smiling Buddha," under her leadership. This test marked India's entry into the nuclear club and was aimed at showcasing the country's scientific and technological capabilities. The test received mixed reactions from the international community, with some countries expressing concerns about nuclear proliferation.

Ban on Nuclear Tests:
However, the policy initiative of banning nuclear tests was not included in Mrs. Indira Gandhi's government agenda. The Comprehensive Nuclear-Test-Ban Treaty (CTBT), which bans all nuclear explosions, was opened for signature in 1996, long after her tenure as Prime Minister. India has not signed the treaty, citing concerns about the discriminatory nature of the treaty and the need for global disarmament. The country maintains a policy of no-first-use of nuclear weapons and has been advocating for a world free of nuclear weapons.

In conclusion, while Mrs. Indira Gandhi's government implemented several significant policy initiatives such as the abolition of privy purse and nationalisation of banks, the ban on nuclear tests was not included in her government's agenda.
