Q1. Define the scope and uses of farm power sources. Explain the different types and features of farm power sources.
- Farm power is essential for efficient, timely agricultural operations, boosting productivity and reducing drudgery.
- Scope covers all farm stages: tillage, sowing, irrigation, harvesting, processing, and transport.
- Human power is cheapest, low output (0.05-0.1 hp), for small-scale, precision tasks.
- Animal power (0.5-1.0 hp/animal) is renewable, low cost, adaptable, but susceptible to fatigue.
Answer: Farm power refers to the energy input required to perform various agricultural operations efficiently, thereby enhancing productivity and reducing human drudgery. The scientific application of power is critical for timely farming activities, which directly impacts yield and economic returns. The scope of farm power sources is extensive, encompassing virtually every stage of crop production and post-harvest management. It is primarily used for land preparation (like ploughing, harrowing, and l...
