Dry farming

1. Dry Farming difference between Dry land Farming and Rain fed
Farming

2. Dry Farming
Cultivation of crops in areas where rail fall is
less then 750mm per annum is called dry
farming. Crop failures are more frequent under
dry farming condition. Dry farming regions are
equivalent to arid regions and moisture
conservation practices are important in this
regions.

3. Dry land farming and Rain fed farming
• Dry land farming- Areas which receive an annual
rainfall of 750 mm or more. Dry land farming areas are
grouped under semi-arid regions.
• Rain fed farming- cultivation of crop in regions receiving
more then 1150 mm rainfall known as rain fed farming. It
is practiced in humid regions where crop failures are rare
and drainage is the important problems.

4. Difference Between Dry land Farming And Rain Fed Farming
Constituents Dryland farming Rainfed farming
1. Rainfall (mm)
< 750mm
>750mm
2. Moisture Shortage Enough / Sufficient
3. Growing season
(Days) <200 >200
4. Growing regions Arid and Semiarid & up
lands of sub humid &
humid regions.
Humid and sub humid
regions.
5. Cropping system Single crop or
intercropping
Intercropping or double
cropping.
6. Constraints Wind and water erosion Water errosion.
Principles of agronomy- Reddy and Reddy

5. Characters of dry farming
• Uncertain, ill-.distributed and limited annual rainfall
• Occurrence of extensive climatic hazards like drought,
flood etc.
• Undulating soil surface.
• Practice of extensive agriculture i.e. prevalence of mono
cropping etc.
• Very low crop yield.
• Poor market facility for the produce.
• Poor health of cattle as well as farmers.
General knowledge today

6. Problems of crop production in Dry Farming in India.
1. Moisture stress and uncertain rainfall.
2. Effective storage of rain water.
3. Disposal or dry farming products.
4. Selection or limited crops.
5. low fertility of soil.
6. Inadequate and uneven distribution of rainfall.
7. Late onset and early cessation of rains

7. Dry land crops: It refers to all
such crops which are drought
resistant and can complete their life
cycle without irrigation in areas
receives an annual rainfall less than
750 mm
as sorghum, sunflowers or cotton.

8. Component of effective Dry farming
• Capturing and Conservation of
Moisture.
• Effective Use of Available Moisture
Soil.
• Conservation Control of Input Costs.
• Control of Input Costs.

9. Dry farming in India.
1. About 69 percent of India is dry land – arid, semi-arid
and dry sub-humid and these areas are heavily
populated, Degradation has severe implications for
livelihood and food security for millions of people
living in these areas.
2. An estimated 32 percent of India’s total land area is
affected by land degradation (of which desertification is
a major component) 81.45 million hectares, or 24.8
percent of the country’s geographic area is undergoing
desertification.

10. 3.Water and soil erosion are major causes of land
degradation; water erosion is most prominent in
agricultural regions.
4. The key anthropogenic factors resulting in degradation
are unsustainable agricultural practices; diversion of land
to development programmes; industrial effluents; mining
and deforestation.

11. 5. Unsustainable resource management practices
drive desertification, and accentuate the poverty of
people affected by desertification.
6. Land rehabilitation has been a major priority
since Independence, and several policies and
government agencies address desertification and
degradation.
