Principle of Crop Rotation

Principle of Crop Rotation

Crop Rotation

It is defined as the growing of crops in an orderly and well planned way. It depends upon

  • Type of crop sown
  • Local economic factor
  • Traditioning

Objective of crop rotation

  1. To prevent the built up of insect pest, weeds and soil born diseases
  2. To maintain soil fertility for the next crop
  3. To conserve soil erosion which may cause from wind or water
  4. To conserve soil moisture from one season for the next
  5. To ensure a balanced programme of work throughout the season

Principle of crop Rotation

The traditional principles on which the planning of crop rotations is based are following which are helpful for the best crop rotation

  1. Alternating growing of crops with differential ability to absorb nutrients from the soil or having different root depth
  2. A planned succession of crops that take it to account any detrimental or beneficial effects of one crop on the following crop. These affects may be due to toxic organic matter, soil structure, soil micro organisms or residual soil moisture
  • Alternating crops susceptible to certain diseases with those that are resistant ( alternate host provision)
  1. Alternating soil exhausting crops with crops that contribute to the improvement of soil fertility
  2. Alternating crops with different peak requirements of labor and water etc.

The traditional crops rotation is in general exhausting and makes no contributions to soil fertility. The basic problem is therefore to device a crop rotation that will raise the level of soil fertility thus making it possible for the following crop to benefit fully from the favorable moisture require prevailing during its growing periods. It is frequently assumed that pulses are desirable proceeding crops for the winter cereals and it was originally that increasing the area under pulses would have beneficial effects on soil fertility. However results are always disappointing at harvesting. A seed crop from the legume usually result in a drop of at least 30% in the yield of the following wheat crop as compared with following wheat with fallow

Legume (seed) ______ Wheat (30%loss)

Wheat ____________ Fallow ________ Wheat

Leguminous crops that are not allowed to mature seed but are used for green manure, hay, silage, have been shown to improving the soil fertility. When a deep rooted legume crop such a lucern is turned under for green manure, the soil has usually dried out to a depth of several feet when the legume is cut before seed I formed the amount of plant nutrients removed from the soil is relatively small while the soil is enriched in nitrogen and organic matter.

Factor affecting crop rotation

  • Climate

Climate is the one of most important factor which is effect the crop rotation either by wind, rain or other factors.

  • Type and nature of soil

Type and nature of soil is also important factor which effects the crop rotation some soil are fertile and some are low in fertility

  • Availability of inputs

Availability of inputs at the place is also effects the crop rotation like fertilizer, pesticide etc

  • Availability of labor

Availability of labor is effect the crop rotation. The labor is required at the critical stages of crop if the labor is not available at that time the crop may cause loss

  • Situation of farm

The farm location is also very important factor which is effect the crop rotation.

  • Size of Farm

The size of farm is effects the crop rotation. Small land holding is major problem in Pakistan that’s why crop rotation is effect by the farm size

  • Type of farming

Type of farming is also effect the crop rotation

Types of crop Rotation

  1. According to residual effect on soil
  • Exhaustive rotation
  • Restorative rotation
  1. According to periods of time
  • Fixed Rotation
  • Flexible rotation


The crop rotation is very important in the Agriculture. Crop rotation done according to the principle of crop rotation it can help full in maintain the soil fertility.
