Alternate Land Use System in Detail

Land Use System

Uncertain rainfall, poor soil conditions and low level of management has made annual cropping of field crops a non-remunerative enterprise in many pockets of dry lands. In some instances, cropping has been given up altogether and lands remain fallow and become wastelands overgrown with unwanted vegetation. To arrest this trend and to bring back the land under economically useful vegetation, alternate land use systems such as grasslands/pastures, agroforestry and horticulture are recommended. This has become necessary for the following reasons:

• Annual field crop production is nonviable and uneconomical in many years.

• Yield of field crops is low and fluctuates widely between years affecting stability and income.

• Continued use of the eroded and degraded lands under the present system of annual cropping may ecologically degrade the lands further affecting sustainability of the fragile eco-system in the dry lands, leading to the creation of wastelands.

• Alternate land use systems such as grasslands and tree culture are less risky, more productive and remunerative in these marginal lands. They will provide stability and sustainability.

The choice of an alternate land use system depends on the land capability. Most of the lands under dry farming tracts come under the land capability classes of III and above.

Land capability class Alternate land use recommended
Class II Dry land horticulture
Class III and IV Agro-forestry/ley farming
Class V Pastures/silvipasture/tree farming
Class VI Range lands/wood lots

A. Pastures and Grasslands

Forage crops play an important role in dry land economy. They help to promote livestock husbandry to improve and stabilize income. Forage grasses and legumes are best suited for marginal lands and sub marginal lands, sloppy lands, eroded and degraded lands for soil and moisture conservation and for reclamation of wastelands.

B. Forage Crops

Forage crops for dry lands include:

Annual cereals – Sorghum, maize, pearl millet

Annual legumes- Cowpea, cluster beans (guar)

Perennial grasses-

  • Cenchrus ciliaris (Anjan or Kolukkattai grass)
  • Cenchrus setigerus (black kolukkattai)
  • Cenchrus glaucus (blue buffel)
  • Dichanthium annulatum (marvel grass)
  • Chloris gayana (Rhodes grass)
  • Heteropogon contortus (spear grass)
  • Annual grass- Pennisetum pedicellatum (Deenanath grass)

Perennial legumes-

  • Stylosanthes hamata, Stylosanthes scabra (Stylo or muyal masal)
  • Macroptilium atropurpureum (siratro)
  • Clitoria ternatea (sangupuspham)
  • Desmanthus virgatus (Hedge lucerne/velimassal)
  • Leuceana leucocephala (subabul), berseem.
