Agricultural Marketing & Agri-Business :: Agro Processing

  • Storage and Warehousing
  • Cold Storage


    Storage is an important marketing function, which involves holding and preserving goods from the time they are produced until they are needed for consumption.
  • The storage of goods, therefore, from the time of production to the time of consumption, ensures a continuous flow of goods in the market.
  • Storage protects the quality of perishable and semi-perishable products from deterioration;
  • Some of the goods e.g., woolen garments, have a seasonal demand. To cope with this demand, production on a continuous basis and storage become necessary;
  • It helps in the stabilization of prices by adjusting demand and supply;
  • Storage is necessary for some period for performance of other marketing functions.
  • Storage provides employment and income through price advantages.


Underground Storage Structures

Underground storage structures are dugout structures similar to a well with sides plastered with cowdung. They may also be lined with stones or sand and cement. They may be circular or rectangular in shape. The capacity varies with the size of the structure.


  • Underground storage structures are safer from threats from various external sources of damage, such as theft, rain or wind.
  • The underground storage space can temporarily be utilized for some other purposes with minor adjustments; and
  • The underground storage structures are easier to fill up owing to the factor of gravity.

Surface storage structures

Foodgrains in a ground surface structure can be stored in two ways - bag storage or bulk storage.

1.Bag storage

  • Each bag contains a definite quantity, which can be bought, sold or dispatched without difficulty;
  • Bags are easier to load or unload.
  • It is easier to keep separate lots with identification marks on the bags.
  • The bags which are identified as infested on inspection can be removed and treated easily; and
  • The problem of the sweating of grains does not arise because the surface of the bag is exposed to the atmospheres.

1.Bulk or loose storage


  • The exposed peripheral surface area per unit weight of grain is less. Consequently, the danger of damage from external sources is reduced; and
  • Pest infestation is less because of almost airtight conditions in the deeper layers.
  • The government of India has made efforts to promote improved storage facilities at the farm level.

Improved grain storage structures

1.For small-scale storage

  • PAU bin
  • This is a galvanized metal iron structure. It s capacity ranges from 1.5 to 15 quintals. Designed by Punjab Agricultural University.

  • Pusa bin
  • This is a storage structure is made of mud or bricks with a polythene film embedded within the walls.

  • Hapur Tekka
  • It is a cylindrical rubberised cloth structure supported by bamboo poles on a metal tube base, and has a small hole in the bottom through which grain can be removed.

    1.For large scale storage

  • CAP Storage (Cover and Plinth)
  • It involves the construction of brick pillars to a height of 14" from the ground, with grooves into which wooden crates are fixed for the stacking of bags of foodgrains. The structure can be fabricated in less than 3 weeks. It is an economical way of storage on a large scale.

  • Silos

In these structures, the grains in bulk are unloaded on the conveyor belts and, through mechanical operations, are carried to the storage structure. The storage capacity of each of these silos is around 25,000 tonnes.


Warehouses are scientific storage structures especially constructed for the protection of the quantity and quality of stored products.

  • Scientific storage
  • The product is protected against quantitative and qualitative losses by the use of such methods of preservation as are necessary.

  • Financing
  • Warehouses meet the financial needs of the person who stores the product. Nationalized banks advance credit on the security of the warehouse receipt issued for the stored products to the extent of 75 to 80% of their value.

  • Price Stabilization
  • Warehouses help in price stabilization of agricultural commodities by checking the tendency to making post-harvest sales among the farmers.

  • Market Intelligence
  • Warehouses also offer the facility of market information to persons who hold their produce in them.

Working of Warehouses

  • Acts: - The warehouses (CWC and SWCs) work under the respective Warehousing Acts passed by the Central or State Govt.
  • Eligibility: - Any person may store notified commodities in a warehouse on agreeing to pay the specified charges.
  • Warehouse Receipt (Warrant): - This is receipt/warrant issued by the warehouse manager/owner to the person storing his produce with them. This receipt mentions the name and location of the warehouse, the date of issue, a description of the commodities, including the grade, weight and approximate value of the produce based on the present prices.
  • Use of Chemicals: - The produce accepted at the warehouse is preserved scientifically and protected against rodents, insects and pests and other infestations. Periodical dusting and fumigation are done at the cost of the warehouse in order to preserve the goods.
  • Financing - The warehouse receipt serves as a collateral security for the purpose of getting credit.
  • Delivery of produce: - The warehouse receipt has to be surrendered to the warehouse owner before the withdrawal of the goods. The holder may take delivery of a part of the total produce stored after paying the storage charges.

Types of warehouse

1. On the basis of Ownership

  • Private warehouses: These are owned by individuals, large business houses or wholesalers for the storage of their own stocks. They also store the products of others.
  • Public warehouses: These are the warehouses, which are owned by the govt. and are meant for the storage of goods.
  • Bonded warehouses: These warehouses are specially constructed at a seaport or an airport and accept imported goods for storage till the payment of customs by the importer of goods. These warehouses are licensed by the govt. for this purpose. The goods stored in this warehouse are bonded goods. Following services are rendered by bonded warehouses:
  • The importer of goods is saved from the botheration of paying customs duty all at one time because he can take delivery of the goods in parts.
  • The operation necessary for the maintenance of the quality of goods - spraying and dusting, are done regularly.
  • Entrepot trade (re-export of imported goods) becomes possible.

2. On the basis of Type of Commodities Stored

  • General Warehouses: These are ordinary warehouses used for storage of most of foodgrains, fertilizers, etc.
  • Special Commodity Warehouses: These are warehouses, which are specially constructed for the storage of specific commodities like cotton, tobacco, wool and petroleum products.
  • Refrigerated Warehouses: These are warehouses in which temperature is maintained as per requirements and are meant for such perishable commodities as vegetables, fruits, fish, eggs and meat.
