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.

India. The experiment was laid out in split-plot design with two crop establishment methods viz., C1-Conventional tillage, C2-Zero tillage and four nitrogen levels viz. N1-90 kg ha-1, N2-120 kg ha-1 , N3-150 kg ha-1 and N4-180 kg ha-1 in the main plot and four time of nitrogen application treatment viz. T1: 25% N as basal + 50% N at active tillering stage + 25% N at panicle initiation stage; T2:15% N as basal +22.5% at 15-20 DAS+ 40% N at active tillering stage + 22.5% N at panicle initiation stage; T3: 33.3 % N at 15-20 DAS + 33.3 % at active tillering stage + 33.3 % at panicle initiation stage; T4: 25% N at 15-20 DAS+ 25% N at active tillering stage + 25% N at panicle initiation stage + 25% N at heading in sub-plots for both the years. In case of crop establishment method, significantly lowest weed density (m-2), weed dry matter (g m-2) and higher grain and straw yield was recorded with zero till DSR (C2) compared to conventional DSR (C1) at all the crop growth stages Among the nitrogen levels, 90 kg N ha-1 recorded lowest weed density (m-2), weed dry matter (g m-2) and significantly higher yield was observed with 150 kg N ha-1 which is at par with 180 kg N ha-1 compared to rest of the nitrogen levels at all the crop growth stages during both the year of the experimentation. With regards to time of nitrogen application, lowest weed density (m-2) and weed dry matter (g m-2) was recorded under the treatment (T4) 25% N at 15-20 DAS+ 25% N at active tillering stage + 25% N at panicle initiation stage + 25% N at heading which was at par with treatment (T3) 33.3 % N at 15-20 DAS + 33.3 % at active tillering stage + 33.3 % at panicle initiation stage at 20 DAS. However, at 40 and 60 DAS significantly lowest weed density (m-2) and weed dry matter (g m-2) was recorded by treatment (T1) 25% N as basal + 50% N at active tillering stage + 25% N at panicle initiation stage which was at par with treatment (T4) 25% N at 15-20 DAS+ 25% N at active tillering stage + 25% N at panicle initiation stage + 25% N at heading compared to rest of the treatments during both the years of experimentation. However, about grain and straw yield treatment (T3) 33.3 % N at 15-20 DAS + 33.3 % at active tillering stage + 33.3 % at panicle initiation significantly influenced grain yield and straw yield respectively as compared to rest of the treatments and at par with treatment (T2) 15% N as basal +22.5% at 15-20 DAS+ 40% N at active tillering stage + 22.5% N at panicle initiation stage. During both the years of experimentation.
