Department of Agriculture, Assam

WATER MANAGEMENT & DRY LAND FARMING IN ASSAM
  • Even with annual rainfall of 2296.3 mm(2011) suffer from moisture stress
  • Most of the rainfall received during monsoon (Jun-Sept) and major portion of the rainwater is lost through run off, causing erosion, adding water logging of low areas
  • After monsoon less water in profile to support agril production
major constraints
MAJOR CONSTRAINTS
  • Degradation of crop field due to water logging, siltation is very common.
  • Soil erosion by high velocity run off.
  • Low rain water use efficiency.
  • Less investment in water use efficiency.
  • Inappropriate Natural resource management practices followed by farmers.
  • Lack of proper technique available for dry land farming suitable for the region .
major constraints5
MAJOR CONSTRAINTS
  • Due to erratic behaviour & improper distribution of rainfall agriculture becomes risky ,farmers do not want to adopt proper methods , tools whatever available for dryland farming.
  • Loss of soil fertility due to high velocity run off for undulating topography.
  • Low investment
  • Traditional cultivation
  • Low use of fertilizers
  • Shifting cultivation.
extent of land degradation other problems
EXTENT OF LAND DEGRADATION & OTHER PROBLEMS
  • Waterlogged in crop field in summer due to poor management of seasonal stream going through the field.
  • Crop field affected due to siltation from seasonal stream
  • Gully formation in crop field, rapid top soil erosion in hilly districts

AGRONOMIC MANAGEMENT, DIVERSIFICATION INTO LOW WATER INTAKE CROPS ETC.
  • Govt. assistance for large scale production of Vermi compost under different scheme to increase the use organic matter.
  • Growing of Black gram , Green gram in water stressed area.
  • Maize is introduced in water stressed pockets.
  • Popularization of cultivation of Green Manuring Crops like Dhaincha.
slide32

INDEGENOUS & USEFUL CROP / PLAN VARIETIES

& PRACTICES BY FARMERS

  • Cultivation of Banana, Ginger, Turmeric by mulching with paddy straw.
  • Putting check-dam on seasonal streams for surface irrigation.
  • Zero Tillage in Rabi Vegetable cultivation.
suggestions
SUGGESTIONS
  • Cultivation of non traditional crops like medicinal plant, dye providing crops etc are also to be encouraged in dry land farming
  • Application of organic matter, green manuring to be promoted.
  • Proper crop rotation.
  • Water harvesting, management of drainage lines in field to be encouraged in community approach.
  • Research to evolve flexible cropping system & other aspects of dryland farming targeting to generate marketable surplus.
  • Conversion of area under Shifting Cultivation to permanent land use system.
