The area of agricultural land that can be irrigated by one cusec (cubic foot per second) of water varies depending on several factors. Generally, one cusec can irrigate approximately 30 to 60 acres of land. This range accounts for crop type, soil characteristics, climate conditions, and irrigation efficiency differences. For instance, water-intensive crops like rice may require more water, reducing the irrigated area, while efficient irrigation methods like drip systems can increase coverage. Soil type affects water retention, with sandy soils requiring more frequent irrigation than clay soils. Climate factors such as temperature, humidity, and wind influence water requirements. It's important to note that this estimate is a general guideline, and actual irrigation capacity can vary significantly based on local conditions and agricultural practices.

The amount of agricultural land that can be irrigated by 1 cusec (cubic feet per second) of water varies depending on crop type, soil, climate, and irrigation efficiency. On average, a cusec can provide roughly 1.98 acre-feet, or 86,400 cubic feet of water each day. Surface irrigation may irrigate 0.66 to 1.32 acres daily, whereas 1 to 2 acres could be covered daily by more effective techniques like drip or spray systems. The area watered by 1 cusec throughout a growing season is determined by the crop's total water consumption, soil moisture retention, and the local climate, with the potential for 0.4 acres per day when seasonal needs are considered.
