The advantages

save cost.

grows very fast.

the yield of rice increases each yearbecause the rice can be harvested a

few times a year in shorten

harvesting time.

less water needed to irrigate the

fields.

1. Technique for growing certain crops

using culture solutions to provide all the

nutrients needed by the plants.

2. The method is the plants do not grow in

soil.

3. The plants are supported in special

containers which contains sand or

pebbles and a culture solution to supply

all the nutrients needed by the plants.


12/34

4. The roots are immersed in all aerated

solution containing the correct

proportions of essential minerals such as

macronutrients and micronutrients

5. The culture solution in the containers is

replenished from time to time as they are

being used by the plants.

The advantages

plants can be carried out anywheresince it does not require soil

temperature and light intensity can be

controlled the methods are space-saving since

the plants can be planted close

together since the plants are supplied with all

nutrients they need, they grow more

healthily and have better yield.

Breeding is the process of

producing offspring of and

animals with better quality fromthe mating of both parents with

high quality characteristics.

Different animal species with

certain beneficial characteristics

are selectively bred.

The process of producing offspring of

plants and animals with better quality

from the mating of both parents withhigh quality characteristics.

The breeding of plants are differentplant species with certain beneficial

characteristics are selectively bred.


22/34

The advantages

produce more milk with low fat

content

provide a lot of meat. increased nutritional values

higher yieldsgreater resistance to disease and

climatic change.


23/34

A technique that involves the growth of

tissues of living organisms outside the

body in a suitable culture medium.

Meristem tissues from the tips of shoots

and roots are removed from the plant.

They all then cultured in a culture solution

that contains all the nutrients required for

growth.


24/34

Examples of plants

PapayaPineapples

Star fruits


25/34

The advantages

produce offsprings with the same

good quality characteristics of the

parent .

can produce offsprings in large

numbers.


26/34

This technique involvestransferring genes from an

organism into the DNA of another

organism to alter thecharacteristics of the organism.


27/34

Examples of plants

Tomatoes

Potato


28/34

The advantages

speeds up the breeding process

of plants and live-stock

produces offsprings faster than bymating

crops and animal of good qualityare produced.


29/34

Surface of the soil must always becovered by plants to prevent soil

erosion and the loss of nutrients.


30/34

Examples of plant

Watermelons


31/34

The advantages

can reduce soil erosion

leaching of nutrients from the soil

and addition of organic matter

which promotes humus formation

improves soil structure.


32/34

A method of controlling pests byusing an organism which is a

pest.
