The foundational decades focusing on agriculture, rapid industrialization, and self-reliance.
- First Five Year Plan (1951-56): Based on the Harrod-Domar Model. Main focus was on agriculture, irrigation, and power projects. Multipurpose dams like Bhakra Nangal, Hirakud, and Damodar Valley were initiated. Achieved a growth rate of 3.6% against the target of 2.1%.
- Second Five Year Plan (1956-61): Based on the Mahalanobis Model (PC Mahalanobis). Focused on rapid industrialization and heavy industries. Steel plants at Rourkela, Bhilai, and Durgapur were established with foreign collaboration. Industrial Policy Resolution of 1956 was adopted.
- Third Five Year Plan (1961-66): Targeted self-reliant and self-generating economy. Suffered severe setbacks due to the Sino-Indian War (1962), Indo-Pak War (1965), and severe drought (1965-66). Led to the introduction of Green Revolution inputs and Devaluation of the Rupee (1966).
- Plan Holiday (1966-69): Due to the failure of the Third Plan, three Annual Plans were executed. High priority was given to agriculture, allied activities, and industrial production stabilization.
- Fourth Five Year Plan (1969-74): Based on Gadgil Formula. Emphasized 'Growth with Stability' and 'Progressive Achievement of Self-Reliance'. 14 major commercial banks were nationalized (1969), and the 'Garibi Hatao' slogan was coined.
