Today, 8th April 2019, Prime Minister Narendra Modi launched his BJP party's manifesto. It is also named as Sankalp Patra, a document promising good governance, security, and prosperity of the country.
Through this answer, I would like to give a quick glance at the BJP 2019 mission statement. It repeats many promises it had made in the 2014 manifesto.

Double income of farmers by 2022. All Indian farmers will not get the benefit of Interest-free Kisan credit card loans, short term agricultural loans up to Rs. 1 lakh.
This loan will be given 0% interest, for the period upto to 5 years. However, the condition is that it needs to be prompt payment.
It further promises to make a total investment of Rs 25 lakh crore. This investment will be used for the productivity of the farm sector.

Pradhan Mantri Kisan Samman Nidhi Yojana will also come into effect. This scheme will ensure financial support to farmers. Farmers with land up to 2 hectares will be benefited through extended land by the BJP government. It covers almost all farmers for the benefits.
Investment of around Rs.100 lakh crore is promised in the infrastructure sector by 2024.
 
Tax benefits will be considered by revising the tax slabs. This aims to maintain enough cash and greater purchasing power in the hands of our middle-income families.

BJP also covers its plan for India's economy. Manifesto claims to make India as a third largest economy of the world by 2030. It has strongly targeted to make India a US $5 trillion economy by 2025 and US $10 trillion economy by 2032.
