Farming in humid regions with growing period more than 120 days
Show Hint
To remember the classifications:
- Dry Farming: \(<\) 750 mm rainfall, \(<\) 75 days growing period.
- Dryland Farming: 750-1150 mm rainfall, 75-120 days growing period.
- Rainfed Farming: \(>\) 1150 mm rainfall, \(>\) 120 days growing period.
Step 1: Understanding the Concept:
Agricultural systems in non-irrigated regions are classified into dry farming, dryland farming, and rainfed farming.
This classification is based on annual rainfall, the length of the crop-growing period, and the climate of the region. Detailed Explanation:
Let us review the characteristics of these different farming systems:
- Dry Farming: Practiced in arid regions with an annual rainfall of less than 750 mm.
The crop-growing period is extremely short, usually less than 75 days.
The primary focus is on conserving soil moisture.
- Dryland Farming: Practiced in semi-arid regions where annual rainfall ranges from 750 mm to 1150 mm.
The growing period ranges from 75 to 120 days.
Common practices include conserving moisture and managing drainage to handle occasional excess water.
- Rainfed Farming: Practiced in humid and sub-humid regions with an annual rainfall of more than 1150 mm.
The crop-growing period is long, exceeding 120 days.
Because rainfall is abundant, soil moisture conservation is not a limiting factor; instead, the primary focus is on soil drainage and erosion control.
- Conservation Farming: This refers to a general management system based on minimal soil disturbance, permanent soil cover, and crop rotation, rather than a classification based on regional rainfall. Step 2: Final Answer:
Farming in humid regions with a growing period of more than 120 days is classified as rainfed farming.
