Agricultural Productivity

Agricultural productivity refers to the ratio of agricultural output to input. In the context of the Indian economy, it is measured in two primary ways: Yield per Hectare (land productivity) and Output per Worker (labor productivity). While India has made significant strides since the Green Revolution, its productivity levels remain lower than global benchmarks in several categories.

Determinants of Agricultural Productivity

Productivity in the Indian context is influenced by a combination of natural, technical, and institutional factors.

• Technological Factors: The use of High-Yielding Variety (HYV) seeds, chemical fertilizers, pesticides, and the degree of farm mechanization.
• Institutional Factors: Land tenure systems, size of holdings, and the availability of formal credit through institutions like NABARD and Commercial Banks.
• Infrastructure Factors: Access to perennial irrigation, rural electrification, all-weather roads, and organized marketing facilities (APMCs).
• Natural Factors: Soil fertility, topography, and the distribution of rainfall (monsoon dependency).

Comparative Analysis of Crop Yields

Despite being a top global producer by volume, India’s yield per hectare for major staples often lags behind countries like China, Brazil, and the USA.

Key Challenges Limiting Productivity

The “yield gap”—the difference between potential yield and actual field yield—is attributed to several structural bottlenecks in the Indian economy.

1. Low Level of Mechanization

Indian farm mechanization stands at approximately 40–45%, whereas it exceeds 90% in developed economies. Small landholdings make the adoption of heavy machinery economically unfeasible for nearly 86% of farmers.

2. Imbalanced Fertilizer Use

The ideal NPK (Nitrogen, Phosphorus, and Potassium) ratio is 4:2:1, but in India, it is often skewed toward Nitrogen (Urea) due to heavy subsidies. This leads to soil toxicity and declining “Partial Factor Productivity” (PFP).

3. Water Inefficiency

India uses 2 to 3 times more water to produce one unit of food grain compared to China or Brazil. The dominance of “flood irrigation” rather than “micro-irrigation” (Drip/Sprinkler) leads to wastage and soil salinity.

4. Disguised Unemployment

Labor productivity is low because the agricultural sector “absorbs” surplus labor that cannot find work in the industry or service sectors. The marginal productivity of this labor is often near zero.

Government Initiatives to Enhance Productivity

The Government of India has shifted its focus from “Production-centric” to “Productivity and Income-centric” through various flagship schemes.

• Soil Health Card (SHC) Scheme: Launched in 2015 to inform farmers about nutrient deficiencies and recommended fertilizer doses to improve soil health.
• Pradhan Mantri Krishi Sinchayee Yojana (PMKSY): Focused on “Har Khet Ko Pani” (water to every field) and “Per Drop More Crop” (improving water use efficiency).
• National Mission on Sustainable Agriculture (NMSA): Aims to make agriculture more productive, sustainable, and climate-resilient.
• Sub-Mission on Agricultural Mechanization (SMAM): Provides subsidies for the purchase of farm equipment and promotes “Custom Hiring Centers” (CHCs) for small farmers.
• Paramparagat Krishi Vikas Yojana (PKVY): Promotes organic farming to improve long-term soil productivity and output quality.

• Yield Gap: In India, the realized yield is often only 30% to 50% of the potential yield obtainable with optimum inputs.
• Vertical vs. Horizontal Growth: Since the net sown area in India has plateaued at around 141 million hectares, future growth in the Indian economy must come from “Vertical Growth” (increasing productivity per unit of land).
• Total Factor Productivity (TFP): This measures the portion of output not explained by the amount of inputs used in production. Its level is determined by how efficiently and intensely inputs are utilized.
• Fertilizer Consumption: Pondicherry and Punjab have some of the highest per-hectare fertilizer consumption rates in India.
• Cropping Intensity: Punjab has the highest cropping intensity in India (approaching 190%), meaning the land is used almost twice a year for different crops.

Productivity in Allied Sectors

The Indian economy increasingly relies on “Allied Sectors” where productivity growth has been faster than in traditional crop farming.

• Livestock: India is the largest milk producer, but the milk yield per animal is significantly lower than in the US or New Zealand. The Rashtriya Gokul Mission aims to improve the genetic makeup of the cattle population to boost productivity.
• Fisheries: Productivity in inland fisheries (aquaculture) has surpassed marine fisheries, contributing significantly to the GVA of the primary sector.
• Horticulture: Under the Mission for Integrated Development of Horticulture (MIDH), India has seen a “Golden Revolution,” where horticulture production has surpassed total food grain production in recent years.
