چکیده
The experiment was conducted at Zonal Agricultural Research Station, Vishwesharaiah Canal Farm, Mandya during 2018-19 to study the nutrient uptake (NPK), use efficiency and grain yield of rice (Oryza sativa L.) in different establishment methods under varied management practices. laid out a split plot design with three replications. main comprised viz., semi dry rice, drum seeded transplanted whereas subplot had five nitrogen, phosphorous potash by plant grain, straw total statistically on par among methods. Further, application 150% Recommended dose inorganic fertilizers (RDIF) recorded significantly higher phosphorus potassium uptake. Among methods, Nitrogen Use Efficiency (NUE) (64.40 kg kg-1), but Phosphorus (PUE) (88.38 101.72 kg-1) Potassium (KUE) (114.76 129.82 were between NUE (90.73 Leaf Color Chart (LCC) based nitrogen management, PUE (108.36 as per UAS (B) package practices KUE (149.16 100% RDIF treatments. recoded (5521 6242 ha-1), however superior (6687 ha-1).
