Hydroponics/ Soilless culture has evolved as a result of research into alternative methods that can be used to overcome various constraints that may arise in soil cultivation.

In 1929, Dr William N. Grieke of the University of California successfully cultivated a tomato plant in an aquatic nutrient medium, which he called hydroponics. Hydro in Greek means water and phones mean active. That is, the ideas here would mean hydroponics.

Initially, only cultivation in nutrient liquids was referred to as hydroponics, but today all cultivations with or without the use of any other medium or with the help of a nutrient fluid are referred to as irrigated cultivations.

There are several ways in which irrigated cultivation can be done.

  1. cultivation in nutrient solution (Solution culture or liquid hydroponics) (two forms).
    • Circulation methods in closed systems (here also 02 modes.)
      1. Nutrition film materials technology (Nutrient film technique - NFT)
      2. Deep Nutrition current technology (Deep flow technique - DTP)
    • Non-circulating solvent methods in open systems. Here are 03 methods )
      1. aqueous nutrient medium first rampant cultivation technology (Root Dipping Technique)
      2. floating layer cultivation technology (Floating Technique)
      3. Capillary absorption cultivation technology ( Capillary action Technique)
  2. Solid media cultivation ( Solid culture media or Aggregate system) ( form four.) You can also use open or closed system farming structures.
    1. Vertical bag technology - Hanging bag technique
    2. Horizontal grow bag technology - Horizontal grow bag Technique
    3. Cultivation technique in a solid medium filled drains or beds - Trench or troughmTechnique
    4. Pot Technology - Pot Technique
  3. Aerobic Cultivation - Aeroponics (02 types)
    1. Cultivation technology in a nutrient solution cloud - Fog Feed Technique
    2. Cultivation technology in nutrient dispersion - Root Mist Technique

When choosing a suitable method from these cultivation methods, attention should be paid to the availability of environment, financial facility, cheap and readily available medium, the yield available in a single field, product appearance, color, quality without harmful microorganisms etc.

A wide range of crops can be grown under this method of cultivation and salads, fruit salads, kankun and gotu kola can be grown as leafy vegetables. Fruits such as tomatoes, fish, chillies, brinjals, cucumbers, radishes, beans, beets, lentils, cabbage, cauliflower, and fruits such as strawberries, melons, anthuriums, goliaths, roses, marigolds, orchids, gerberas, mint, And flowering plants such as carnations can also be grown.

Compared to traditional agriculture, irrigated cultivation has many benefits.

  • It does not require a lot of lands and can be grown in apartments
  • Soil disinfection, soil fertility, improvement, weeding, watering, labour-intensive methods can be avoided by not using soil. This will enable continuous cultivation throughout the year. This allows for a year-round market-oriented manufacturing process.
  • This method helps to control soil-borne pathogens and pests.
  • With the right control, higher yields can be obtained and many crops can be harvested faster.
  • Has the ability to grow a wide range of vegetable and flower varieties.

However, the high cost of capital, formal technical knowledge of cultivation and the need for suitable manpower and the need for fuel or electricity to operate the unit can be cited as difficulties in this cultivation method.
