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.
Overview The era of modernization is viewed in theentire sectors especially in the agriculture sector.Gone are the days when farmers meant a poorman laboring hard to meet his needs. In themodern times, farmers are equipped withagriculture technology that is latest and troublefree.
With the entry and increasing influence ofthe science in the traditional farming, theagriculture industry of the nation is celebratinggreen revolution each moment. The new technologies have helped inutilizing even the small land into loads of profitmaking source. Farmers whether small or big are gettingmore and more aware of the fact thattechnology is very beneficial to them and thefuture of the agriculture industry.
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.
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.
• 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.
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.
• 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)
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.
• Notice some sprinkler heads are off while others are active. This is due to broadband wireless monitoring technology.
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.
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.
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
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.
• 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.
• 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.
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.
• 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.
