Dry farming

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. Principles of agronomy- R eddy and R eddy

3. D ry 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. Principles of agronomy- Reddy and Reddy

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. C haracters 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. M oisture 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. 4th National UNCCD Report

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. 4th National UNCCD Report

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. 4th National UNCCD Report
