As of my last knowledge update in January 2022, India does not have an officially declared national vegetable. However, the pumpkin (scientifically known as Cucurbita maxima) is often considered a de facto national vegetable and is widely recognized and used in Indian cuisine.
It’s important to note that the designation of a national vegetable may not be a formal or official status in every country, and the choice can vary. For the most current and accurate information, you may want to check with official government sources or recent updates regarding any national symbols in India.
