Field Crops Production
Agronomy is the science of the production of farm crops. We do not know much of the origin of farm crop production. Roman agriculture was the first of which we got some information from written documents. Primitive man did not grow plants. He lived on leaves, roots, seeds, berries and fruits. Crop production began when man started to cultivate plants.
The early farmer cultivated a limited number of crops, but he grew some grain crops which farmer grows at present. All important farm crops originated from wild species.
Science helped, helps and will help to increase yields of crops. Findings in field and laboratory research are leading to new recommendations for efficient crop production. The farmer who follows the most efficient practices will get high yields. The grower who still farms as his father did when he was a boy is the farmer who does not and will not get high yields of crops.
Every student of agriculture studies factors which influence the plant growth.
