Scope of Agronomy
------------------------

• Availability of chemical fertilizers and herbicides for control of weeds has led to development of a vast knowledge about time, method and quantity of fertilizer and herbicide application.

• Big irrigation projects are constructed to provide irrigation facilities. However, these projects created side effects like water logging and salinity. To overcome these problems, appropriate water management practices are developed.

• Population pressure is increasing but the area under cultivation is static. Therefore, to feed the increasing population, more number of crops have to be grown on the same piece of land in an year. As a result, intensive cropping has come into vogue.

• Similarly, no tillage practices have come in place of clean cultivation as a result of increase in cost of energy.( Fuel prices of oil ).

• Likewise, new technology has to be developed to overcome the effect of moisture stress under dry land conditions.

• As new varieties of crops with high yield potential become available, package of practices has to be developed to exploit their full yielding potential.
