ADifferent agro-climatic zones of Jharkhand, rain fall pattern and known abiotic stresses in each zone.

Three Agro-Climatic zones of Jharkhand are:

  1. Western Plateau Zone
  2. Central and North Eastern Plateau Zone
  • South Eastern Plateau Zone

Agro-climatic zones:

  1. Central and North Eastern Plateau Zone

Characteristics:

  1. Low water relentive capacity of the soil particularly that of uplands.
  2. Late arrival and early cessation of monsoon and erratic and uneven distribution of rainfall.
  3. Lack of safe disposal of runoff water during monsoon and water storage and moisture conservation practices for raising Rabi crops.
  4. Drying of tanks and wells by February results in no Rabi crop production.
  5. Important Crops: Rice, wheat, maize, ragi, potato, Arhar, Rapeseeds, Mustards, Gram and Pulses.

Rainfall Pattern:

The region is highly dependent on the monsoonal rainfall. The distribution of rainfall in not even also.

Abiotic stresses: Abiotic stresses such as drought (water deficit), excessive watering (water-logging/flooding), extreme temperatures (cold, frost and heat), salinity (sodicity) and mineral (metal and metalloid) toxicity negatively impact growth, development, yield and seed quality of crop and other plants.

Uncertainity of rainfall in the major abiotic stress of the region

 

  1. Western Plateau Zone

Characteristics:

  1. Late arrival and early cessation of monsoon.
  2. Erratic /uneven distribution of rainfall.
  3. Low water retentive capacity of soils.
  4. Lack of soil and water conservation practices
  5. Important Crops: Rice, Maize, Barley, Lentil, Seasamum, Groundnut, Potato, Arhar and Gram

Rainfall Pattern:

High rainfall enables rice cultivation but it is totally dependent on monsoon.

Abiotic stresses:

Low fertility of soil is the major abiotic stress in this region

 

  1. South Eastern Plateau Zone

Characteristics:

  1. Uneven distribution of rainfall.
  2. Low water holdaning capacity.
  3. Eroded soils.
  4. Poor soil fertility.
  5. Important Crops: Rice, Wheat, Marwa, Arhar, Linseed

Rainfall Pattern: Uneven rainfall distribution have some rivers as well whose water is used in irrigation.

Abiotic stresses: Low fertility and poor soil fertility
