Citizens, NGOs, religious leaders and other ministers will join Jadeja in his campaign, the "Matru Vandana Yatra", which is expected to continue till May 7 and cover 85 towns and villages in Dhrangdhra constituency in Surendra Nagar district, said an official statement.
According to the schedule, Jadeja will lead the motorcycle rally four days in a week.
Jadeja said his campaign was "a small part" of the larger movement by the state to save girl children.
The minister's constituency, however, does not have the worst sex ratio in Gujarat. The figure for Surendranagar is 924 girls for every 1,000 boys, against 920 girls across the state.
