Relation of agronomy to other sciences
--------------------------------------------------

1. Agronomy is a synthesis of several disciplines like soil science, Agricultural chemistry, crop physiology, plant ecology, biochemistry and economics.
2. The soil physical, chemical and biological properties have to be understood thoroughly to effect modification of the soil environment.
3. It is necessary to understand the physiology of crops to meet their requirements. Developments in these subject help in developing new practices which are simpler and economical to provide favourable environment to the crop. The herbicidal properties of 2,4-D made revolutionary changes in weed control.
4. Advances in economic analysis helped in production of crops economically. For efficient utilization of resources systems approach is better than individualistic approach.
