WHAT IS THE DIFFERENCE BETWEEN MIXED CROPPING ,INTERCROPPING AND CROP ROTATION??????????????
1. Mixed cropping is growing of two or more crops simultaneously on the same piece of land.
It is also known as multiple cropping. This type of cropping leads to an improvement in the fertility of the soil and hence, increase in crop yield because when the two crops are properly chosen the products and refuse from one crop plant help in the growth of the other crop plant and vice-versa.
Mixed cropping is an insurance against crop failure due to abnormal weather conditions.
Some successful mixed cropping practices are:
1.Soyabean + Pigeon pea
2.Maize + udad dal (Black gram)
3.Pigeon pea + Mung dal (Green gram)
4.Groundnut + Sunflower
5.Sorghum + Pigeon pea
6.Wheat + Chickpea
7.Barley + Chickpea
8.Wheat + Mustard
9.Cotton + Groundnut
Mixed cropping, also known as inter-cropping or co-cultivation, is a type of agriculture that involves planting two or more of plants simultaneously in the same field. In general, the theory is that planting multiple crops at once will allow the crops to work together. Possible benefits of mixed cropping are to balance input and outgo of soil nutrients, to keep down weeds and insect pests, to resist climate extremes (wet, dry, hot, cold), to suppress plant diseases, to increase overall productivity and to use scarce resources to the fullest degree.
Crop rotation is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons for various benefits such as to avoid the build up of pathogens and pests that often occurs when one species is continuously cropped. A traditional element of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops. It is one component of polyculture. Crop rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants
hope it helps u... plz.. thumbs up...
2.The growing of different kinds of crops on a piece of land in a preplanned succession is known as crop rotation.
In the rotation of crops, leguminous crops like pulses, beans, peas, groundnut and Bengal gram are sown in-between the seasons of cereal crops like wheat, maize and pearl millet.
The leguminous plants are grown alternately with non-leguminous plants to restore the fertility of the soil.
Planting a leguminous plant will result in nitrogen-rich soil and when a cereal is grown in this soil there is increase in food grain production.
Rotation of crops help in weed control and pest control.
Some successful crop rotation practices are:
Maize + mustard , Rice + wheat etc
3. Inter cropping is the cultivation of two or more crops simultaneously on the same field.
It also means the growing of two or more crops on the same field with the planting of the second crop after the first one has completed its development with a row arrangement.
1.Reduces the plant diseases.
2.Reduces hillside erosion and protects topsoil,
3.Minimizes labor cost on the control of weeds.
4.Utilizes the farm area more efficiently.
HOPE UR DOUBT IS CLEARED :)
