METHODS USED TO IMPROVE THE QUALITY
AND QUANTITY OF FOOD PRODUCTION
Direct seeding, Hydroponics and Aeroponics
Direct Seeding
The seeds are sown directly into the soil by using special machine
Less water needed, plants achieve faster growth and these increase the yields
Example : paddy planting
Hydroponics
Is a commercial technique for growing certain plants in culture solution
The root of the plant are immersed in a solution which contains all the macronutrients in the correct proportion
The culture solution is aerated to provide sufficient oxygen to respiration
Aeroponics
Is a modified technique of hydroponics The plants are suspended in a special
chamber with the roots exposed to the air Nutrient solutions are sprayed onto the roots
of the plant at suitable intervals. Light intensity and temperature can be controlled
Almost all type of vegetables can be cultivated by using this methods and higher yield can be obtained
