Key Points:
• Five-Year Plan Strategies for Agriculture:
• Since the First Five-Year Plan, public investment in agriculture systematically focused on input-led productivity enhancements:
• Agricultural Extension Services (a): Propagating lab-to-land know-how, HYV seeds, and scientific practices through extension workers and Krishi Vigyan Kendras (KVKs).
• Expansion of Irrigation (c): Massive capital allocation for multipurpose river valley projects, canals, and tube-wells.
• Institutional Credit (d): Expansion of rural co-operative credit, nationalization of banks (1969), priority sector lending, and creation of RRBs and NABARD to displace moneylenders.
• Terms of Trade (b): Historically, terms of trade were biased *against* agriculture (industrial protectionism kept agricultural prices depressed relative to manufactured goods) and were not a proactive plan tool.
• Hence, the strategy included (a), (c), and (d).
• Key Takeaway: Five-year plan agricultural strategy consistently prioritized extension services, irrigation expansion, and institutional credit.
