A field experiment was conducted at Research farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, in silty clay loam soil to study the LCC based N management on yield, nutrient uptake and soil available status in two rice genotypes (Jhelum and SR-2) under irrigated conditions. The experiment was laid out in randomized block design with three replications. The treatments included 6 LCC based N management for two rice genotypes which consist of Jhelum and SR-2 were compared with the zero N control and a recommended fixed time N splitting. The results suggested that yield and NPK uptake were significantly higher in LCC ≤ 5 @ 30 and 20 kg N ha-1 as compared to other LCC levels (LCC ≤ 4 and 3 @ 30 and 20 kg N ha-1) and recommended nitrogen level. Among the two cultivars, SR-2 recorded significantly higher yield and NPK uptake over Jhelum. The results further revealed that plots with Jhelum recorded significantly more soil available NPK as compared to SR-2. The lack of difference in soil available nutrient between LCC based treatments and conventional blanket N treatment suggest that LCC based N management could be best option for farmers to save fertilizer N besides maintaining soil fertility.
