2. Objectives
• At the end of discussion students are expected
to:
a. Determine the different agricultural
technologies use this 21st century.
b. Analyze how they function as a technology.
c. Appreciate the utilization of technologies for
agricultural purposes.
3. Overview
The era of modernization is viewed in the
entire sectors especially in the agriculture sector.
Gone are the days when farmers meant a poor
man laboring hard to meet his needs. In the
modern times, farmers are equipped with
agriculture technology that is latest and trouble
free.
4. With the entry and increasing influence of
the science in the traditional farming, the
agriculture industry of the nation is celebrating
green revolution each moment.
The new technologies have helped in
utilizing even the small land into loads of profit
making source.
Farmers whether small or big are getting
more and more aware of the fact that
technology is very beneficial to them and the
future of the agriculture industry.
6. 1. Combine Harvester
• The combine harvester, or simply combine, is a
machine that combines the tasks of harvesting,
threshing, and cleaning grain crops. The objective
is the harvest of the crop; corn (maize), soybeans,
flax (linseed), oats, wheat, or rye, among others.
The waste straw left behind on the field is the
remaining dried stems and leaves of the crop
with limited nutrients which is either chopped
and spread on the field or baled for feed and
bedding for livestock.
8. 2. Agricultural robot Suit
• The robot suit is designed specifically to help
out with tough agricultural work like pulling
radishes.
• The suit has eight motors fitted over the
shoulders, elbows, back and knees to provide
a power boost to the wearer. The current
model weighs 55 pounds and uses 16 sensors
to function.
9. • The goal of the suit
design was to
completely eliminate
the need for aging
farmers to strain
their joints or
muscles while lifting
and moving various
objects.
10. 3. Cultivator
• A cultivator is any of several types of farm
implement used for secondary tillage. One
sense of the name refers to frames with teeth
(also called shanks) that pierce the soil as they
are dragged through it linearly. Another sense
refers to machines that use rotary motion of
disks or teeth to accomplish a similar result.
The rotary tiller is a principal example.
11. • Cultivators stir and pulverize
the soil,
• Either before planting (to
aerate the soil and prepare a
smooth, loose seedbed) or
• After the crop has begun
growing (to kill weeds—
controlled disturbance of the
topsoil close to the crop
plants kills the surrounding
weeds by uprooting them,
burying their leaves to disrupt
their photosynthesis, or a
combination of both)
12. 4. Pivot Irrigation System
• In this device, technology is incorporated into
an ordinary pivot irrigation system, making it a
smart agricultural device.
• Developed by the United States Department
of Agriculture, that records and transmits soil-
moisture levels. This pilot project in Georgia
enables farmers to effectively irrigate soil
without wasting water.
13. • Notice some
sprinkler heads
are off while
others are active.
This is due to
broadband
wireless
monitoring
technology.
14. 5. Tillage system
• Tillage practices can be divided into
'conventional' and 'conservation' tillage.
Conventional tillage creates more soil
disturbance and mixing, while conservation
tillage reduces soil disturbance to a minimum
and keeps more residue from the previous
crop at the soil surface.
15. A. Conventional Tillage
• Conventional tillage operations use
implements to mix or disturb the soil
extensively, burying plant residue in the
process. This leaves a rough surface that is
then disked smooth to allow for better
planting.
16. B. ConservationTillage
• Conservation tillage leaves 30% or more of the
soil surface covered with plant residue, thus
the degree of soil mixing is less than the
conventional tillage system. In the photos,
discing and chisel plows bury some of the
residue compared to no-till surface. Removing
some of the residue by discing or chisel
plowing increases the area of soil exposed to
erosion

19. 6. Holiday Light Technology
• All plants have a unique combination of
photoreceptors, pigments used to specific
frequencies of light. These pigments trigger
different behaviors in the plant, such as leaf
growth, flowering, rooting or even speeding up
and slowing down stem and shoot growth.
• If such techniques were employed by growers,
the result could be stronger plants that produce
more fruit. Farmers may even want to employ
colored mulches and reflective panels to
supplement the effect.
20. • As a demonstration of the technology, they
report using specific light frequencies to
restrict flowering in the early life of strawberry
plants – causing the plants to divert their
resources to growing more runners and
leaves.
21. • Light-emitting diodes (LEDs) are now common
replacements for incandescent bulbs in
applications ranging from coffeemakers to
holiday string lights. They stay cool to the
touch, don’t burn out as easily and use up to
90 percent less energy.
• However, LEDs can also be designed to emit
very specific frequencies of light, and
researchers are using those exacting
frequencies to promote plant growth.
22. 7. Natural product that boosts plant
defense against root pests
• University of Florida researchers have
discovered a natural compound to battle
insect pests that plague gardeners and
growers.
• The compound boosts crops’ resistance to
pest attacks on their roots by recruiting
microscopic worms that kill the insects by
eating them from the inside out.
23. • Researchers, including members of UF’s
Institute of Food and Agricultural Sciences,
made the discovery by studying chemicals
released by citrus roots when they are
attacked by citrus root weevil larvae.
28. Fertilizing and pest control
• Fertilizer spreader (see broadcast seeder)
• Terragator
• Manure spreader
• Sprayer
Irrigation
• Center pivot irrigation
