<p>This study investigates energy usage trends and machinery energy ratios in potato cultivation across 80 farms categorized by size: large, medium, small, and marginal.

Results indicate that smaller farms (small and marginal) consume higher total energy, primarily due to intensive use of organic inputs like farmyard manure, which accounts for over 50% of their energy input.

Field preparation and sowing were the most energy-intensive tasks across all farm sizes. Large farms achieved the highest energy efficiency ratio (2.54), followed by medium (1.61), marginal (1.23), and small farms (1.08), highlighting a positive correlation between farm size and energy efficiency. Machinery energy ratios were highest for large farms (5.35) and lowest for marginal farms (1.99), reflecting more effective mechanization in larger operations.

摘要

This study investigates energy usage trends and machinery energy ratios in potato cultivation across 80 farms categorized by size: large, medium, small, and marginal. Data on energy inputs (e.g., labour, diesel, farmyard manure, fertilizers, chemicals, irrigation, electricity, and seeds) and outputs were analyzed. Results indicate that smaller farms (small and marginal) consume higher total energy, primarily due to intensive use of organic inputs like farmyard manure, which accounts for over 50% of their energy input. Conversely, larger farms exhibit greater energy efficiency, attributed to enhanced mechanization and optimized input management. Field preparation and sowing were the most energy-intensive tasks across all farm sizes. Large farms achieved the highest energy efficiency ratio (2.54), followed by medium (1.61), marginal (1.23), and small farms (1.08), highlighting a positive correlation between farm size and energy efficiency. Machinery energy ratios were highest for large farms (5.35) and lowest for marginal farms (1.99), reflecting more effective mechanization in larger operations. These findings suggest that improving energy efficiency in potato farming, particularly for smaller farms, requires integrating appropriate mechanization with balanced input use to optimize energy returns.
