Abstract: N urea +LCC<3, 25%N FYM +LCC<4, 25%N urea +LCC<4, 25%N FYM +LCC<5, 25%N urea +LCC<5, along with the recommended dose of NPK (150:60:40 kg/ha) were taken for study. The growth parameters likes, plant height (123.66, 121.14cm), number of shoots (528.25, 523.67), dry matter (842.81, 831.67 g), and Leaf area index (7.14, 6.62) were maximum recorded in PA-6444 which was significantly higher over PHB-71 and NDR-359, respectively. While, PA-6444 recorded highest nitrogen, phosphorus and potassium uptake by grain, straw and total which was significantly higher over the both variety PHB-71 and NDR-359.Among nitrogen levels, 25% N urea +LCC<5 was recorded highest nitrogen, phosphorus and potassium uptake by grain, straw and total. The maximum grain yield was obtained with rice cultivar PA-6444 (65.92-64.51 q/ha) which was superior over NDR-359 (59.01-55.99 q/ha) and at with par PHB-71 (63.85-63.30 q/ha). Among the LCC nitrogen based management. The highest biological yield was recorded under 25% N basal as Urea + LCC<5 which was significantly superior over rest of treatments.
