Hydroponics Production



After the invention of hydroponics, intensive and lucrative cultivation in a greenhouse environment became conceivable. The words “hydro-water” and “pones labour” literally mean “working with water.”

Definition: Plants are grown in an inert medium such as gravel, sand, peat, vermiculite, or sawdust to which a nutrient solution containing all of the needed nutrients for appropriate growth and development is added.

Soilless culture: By W.F. Price in USA in the year 1930

Advantages of Hydroponics Production

1.Much greater yields than those obtained from soil-grown plants.

2.It may be employed in areas where conventional agriculture is not feasible.

3.The stuff is always of exceptional quality.

4.Weeds and soil-borne illnesses are no longer a problem.

5.Management costs are lower.

Essentially there are three methods by means of which plants may be grown without soil.

(1) Water Culture (Plant root in solution)

(2) Drip Culture (Sand culture, watered with nutrientsolution)

(3) Gravel Culture (Most widely used). It needs the

following accessories of Hydroponics Production:

(1) Nutrient tank : Made of concrete, wood or metal

(ii) Benches: Gently sloping benches made of concrete or wood.

(ifi) Medium: Crushed graphite of irregular shape

(iv) Solutions : Different chemical solutions

Nutrient Film Technique (NFT), Tube Culture, and Aeroponics are three recent advancements in soilless cultures. (NFT) is a type of water culture in which plants are cultivated with their roots encased in plastic film and nutritional solution is continually circulated.

The nutritional solution is regularly pushed through PVC dress pipes, through which seedlings are placed in the solution running down the bottom of the PVC dress pipes.

Aeroponics is the practise of growing plants in an opaque trough or supporting container where the roots are suspended and bathed in nutrient bath mist rather than solution.
