ABSTRACT
Water and fertilizer are the two costliest inputs in agriculture. Apart from the economics consideration it is also well known that the adverse effect of injudicious use of water and fertilizer on the environment can have far reaching implications. There is, therefore, a need for technological options, which will help in sustaining the precious resources and maximizing crop production without any detrimental impact on the environment. Micro-irrigation is the only option to replace the conventional irrigation method to achieve water-use efficiency.
