As water becoming the scarce resource, micro irrigation is gaining momentum. Drip fertigation ensures required quantity, proper place, proper time, and regular supply of water fertilizer. Fertigation enhances the utilization of fertilizers and crop yield. So, Drip fertigation not only ensures proper utilization of irrigation water, but also is an effective way to improve the yield quality of crops. Nitrogen is the very important nutrient and the N fertilisers are being the costly input, necessary measures are to be taken to minimise the usage of the fertilisers. Hence the drip fertigation is one of the technologies which is to be addressed off. Also Sugarcane, being the high value crop in India, N management in sugarcane also discussed hereunder.
