Field investigation was carried out during Kharif, 2018 with an objective to study the possibility of effect of LCC based nitrogen management on growth of transplanted rice. Treatments included two doses of nitrogen (120 and 150 kg ha-1) applied on basis of LCC- 3 and 4. In turn Nitrogen was applied in 3 equal splits @ 120 kg N ha-1 and (3 and 4) splits with half as basal, remaining @ 150 Kg ha-1. These treatments were evaluated against control, recommended method and Farmers practice with (120-60-40), (180-80-40) RDF respectively applied at fixed time intervals. Results revealed that, N application based on LCC value-4 was more beneficial than LCC-3 in enhancing the growth and yield of rice. LCC-4 at 150 kg N ha-1 (T9) produced significantly higher plant height (107.9 cm) at maturity, number of tillers (339 m-2), leaf area index (2.17), SPAD readings (34.3), dry matter (11,246 kg ha-1) and grain yield (6,533 kg ha-1). With respect to dose of nitrogen 150 kg N ha-1 resulted in more yield than 120 kg N ha-1. The results of the study implied that LCC-4 was found to be effective as a decision tool for optimum N application in rice.
