 ABSTRACT

The efficient use of Nitrogen (N) is one of the essential goals in crop management to achieve a desirable plant production (biomass). N Management is a challenging task and several methods individually or in combination are used to enhance its efficiency. However, only 33 per cent of nitrogen use efficiency (NUE) improved while developing nitrogen management tools and methods. The primary objective to improve nitrogen use efficiency via strategic management such as respective methods, soil testing, plant tissue testing, right ways of fertilizer placement and timing, vegetative indexes (leaf area index) and spectral response etc. No single method was found sufficient to stand the nitrogen loss. Some methods were found time consuming and unsynchronized with N uptake behaviour of crop, for example, plant tissue testing. Use of precision agriculture tools, such as Green Seeker, SPAD meter, and leaf color chart (LCC) were found better as compared to conventional methods such as soil testing, but these tools can only be used when the crop is up. Therefore, N management is possible only through in season N application methods. When 70% of the applied nitrogen is used by the crops within 25-30 days after sowing, for example, corn, it is required to apply major N rates through in season approach and some N at the time of sowing using soil test reports. finally concluded that using two or more methods in combination when managing the N in the crops field.
