Methods to

improvequality &

quantity offood

production

Direct seeding

Hydroponics& Aeroponics

Selectivebreeding

Tissueculture

Geneticengineering

Proper soilmanagement

Biologicalcontrol


2/19

Seeds are directly sowed to the soil

No transplanting

Benefits: plants growth faster & givehigher yields, reduce water

requirement, eliminating thelaborious process of plantingseedlings by hand


3/19

standing waterprevents germination

of competing plants

Machine planting


4/19

Unlike flooded rice fields

direct-seeded rice can be grown

amongst tree crops

HYDRONICSgrowing crops plants in culturesolutioncontaining macro &

micronutrients (in water without soil)


8/19

AEROPONICSgrowing crop plants inair/ mist environment without the use of

soil(no growing medium)

nutrient rich water solution are sprayeddirectly to the roots of plants


9/19

Less space No soil needed Can be carried out on large scale Doesnt require insecticide & pesticides Can be carried out all around the year

Can also be carried out at home The water stays in the system and can be reused -

lower water costs nutrition levels in their entirety can be control- lower

nutrition costs

No nutrition pollution is released into the environmentbecause of the controlled system

Stable and high yields Pests and diseases are easier to get rid of than in soil

because of the container's mobility


10/19

A process by which healthy cropplants/animals are produced

Seeds from healthy plants/ animal with

beneficial characteristics

(high nutritional content, shortermaturity time, higher yields,

higher resistance to diseases)are selected

These healthy seeds/animals than allow togerminate/breed.

The growth

of tissues and/or cells separatefrom the organism

use of a liquid, semi-solid, or solid growthmedium, such as agar

Produces clones with the same desired

characteristics as the parentwithin a short time & large

number


13/19


14/19

Transfer of useful genes from oneorganism to another

Food produced by this method:

genetically modified food

(GMF)


15/19


16/19

Control pests without using

pesticides & insecticides forbetter crop yield

Use snakes and owls to control ratsin oil palm estates


17/19

To prevent food spoilage bymicroorganism

To extent the lifespan of food

To avoid food wastage

To diversify uses of food (eg: variety ofdairy product)

To ensure a sufficient food supply
