Abstract: Presently, 50 percent of the human population relies on synthetic nitrogen (N) fertilizer for food production. In agriculture of subsistence during pre-chemical era, biological N2 fixation (BNF) was the primary source of reactive N but, in recent decades chemical N fixation (synthetic N) has become more important in global agriculture. Today, synthetic N fertilizer introduces reactive N of over 100 Tg N year-1 into the global environment to increase food production. Although this has sustained the large human population in meeting dietary needs, a large agriculture area in the world still lacks available N to sustain the crop production. As regards of split N application the yield and yield contributing parameters were significantly influenced by split application of N. With increase in the number of splits application along with basal application found more effective for improving the production of direct seeded rice. This article gives broad idea about Nitrogen status globally and nitrogen management in direct seeded rice.
