TAILIEUCHUNG - Nitrogen release dynamic of different coated urea under puddle lowland rice cultivation

A research trail was carried out during kharif season 2014-15 to determine release dynamic of nitrogen from different nitrogenous fertilizers and weather effect on release pattern. The result revealed the significant difference between release pattern of nitrogen from coated and uncoated urea. | 2017 6 10 2638-2641 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 10 2017 pp. 2638-2641 Journal homepage http Original Research Article https Nitrogen Release Dynamic of Different Coated Urea under Puddle Lowland Rice Cultivation Rajani and Ajijit Sen Department of Agronomy Institute of Agricultural Science Banaras Hindu University Varanasi-221005 Uttar Pradesh India Corresponding author ABSTRACT Keywords A research trail was carried out during kharif season 2014-15 to determine release dynamic of nitrogen from different nitrogenous fertilizers and Controlled release weather effect on release pattern. The result revealed the significant fertilizer Deep placement Release difference between release pattern of nitrogen from coated and uncoated pattern. urea. There was no-significant difference between polymer coated urea Article Info both single and double layer in N content of soil just after application upto 23 days. No marked difference in soil N content was noticed because of Accepted 23 September 2017 steady temperature during experimentation. Coated urea fertilizers released Available Online N with slower rate than Urea supergranule hence availability of nitrogen 10 October 2017 was there for quite longer period. Introduction Controlled or Slow release fertilizers have sulphur coated urea SCU Neem coated urea been developed to counterpoise disadvantages NCU polymer coated urea nitrification of conventional urea. Urea in soil solubilise inhibitors and urease inhibitor. Trials within 7-10 days after its application. Urea conducted by KRIBHCO showed the applied at sowing planting when need of superiority of neem emulsion coating urea nitrogen is less ensuing wastage of nutrient or over prilled urea. These emulsion coatings fertilizer and in the succeeding growth stages also improves the shelf life of urea and when its requirement .
