ConclusionIt is evident from our results that the use of LCC withreduced the basal N application (30 kg N ha-1) along withcalcium silicate at 2 t ha-1as a source of silicon resultedon par grain yield as compared to the recommended Ntreatments under both aerobic and wetland rice.Monitoring rice plant N status and N requirement is animportant subject with improving the balance betweencrop N demand and N supply from soil and appliedfertilizer. In many field situations in Karnataka, more than50% (50% of total N is supplied as basal application) ofapplied N is lost due in part to the lack of synchrony ofplant N demand with N supply. The LCC is simple andeasy-to-use tool that can help farmers avoid overapplication of N in rice plant. The LCC basedmanagement in rice suggests that N application can besaved with no yield lose by appropriately revising thefertilizer recommendation. Thus, there is considerableopportunity to increase farmers yield and N recoveryefficiency levels through improved N management withthe LCC. In the situation of using fixed-time split Nrecommendations, refining fixed time split Nrecommendations periodically will be needed with thereal-time N management to tackle high spatial andtemporal variability in INS.
