SCOPE OF AGRONOMY
SCOPE OF AGRONOMY
Agronomy is a dynamic discipline. With the advancement of knowledge and better understanding of plant and environment, agricultural practices are modified or new practices are developed for high productivity. For example, availability of chemical fertilisers has necessitated the generation of knowledge on the method, quantity and time of application of fertilisers. Similarly, availability of herbicides for the control of weeds has led to development of a vast knowledge about selectivity, time and method of application of herbicides. Gigantic irrigation projects are constructed to provide irrigation facilities. However, these projects created side effects like waterlogging and salinity. To overcome these prcblems, appropriate water management practices are developed. Population pressure is increasing but area under cultivation is static. More number of crops have therefore, 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. Likewise, new technology was developed to overcome the effect of moisture stress under dryland conditions. As new varieties of crops with high yield potential become available, package of practices has to be developed to exploit their full potential.
