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