A combine harvester cuts down a crop, separates the seed from the plant material and stores the clean grain in a tank for transport or offload to another storage device. The combine is a self-propelled machine that is used by farmers to speed up the process of harvesting.Know More
A combine harvester is used to remove mature crops from a field when they are ready to be harvested. The combine has an attachment on the front, called a header, that is determined by the type of crop being harvested. The header is the portion of the combine that actually cuts the plant. The header then moves the plant up the throat and into the combine itself.
Once the plant has been moved out of the header throat, it is pushed into a threshing cylinder, which is used to separate the grain from the plant. The grain and plant material are passed through the combine over sieve beds. The sieves allow the grain to fall through while moving plant material toward the back of the combine. The clean grain that falls through the sieves is moved by clean grain elevators, augers or air delivery into the grain tank. The plant material is ejected out the back of the combine.Learn more about Agriculture

The seed of a plant is also the plant embryo, which occurs when a pollen grain gets to an ovule and fertilizes it. The fertilized plant embryo contains the seed and nutrient tissues needed to feed the embryo while it begins to grow into a plant.Full Answer >
"Agriculture" is the cultivation of land for effective crop growth and raising of livestock. Farmers engage directly in agriculture by preparing soil, planting crops, harvesting those crops and preparing them for transportation.
