Abstract: A field experiment was conducted in the Instructional Farm of College of Agriculture, Orissa University of Agriculture and Technology, Bhubaneswar during 2017 to study the “Productivity and profitability of summer paddy under different establishment method and irrigation managementâ€. The soil of the experimental site was loamy sand with a BD of (1.84 g/cc), FC of (19%), PWP of (8%) and WHC of (31%). The soil was acidic (pH 5.23), low in organic carbon (0.5%), low in available nitrogen (165.7 kg/ha), low in available phosphorus (4.2 kg/ha) and medium in potassium (271.7 kg/ha).The experiment was laid out in Strip Plot Design with sixteen treatment combinations consisting of four establishment methods viz., Direct Seeded Rice (DSR), Pre Germinate Durm Seeded Rice (PGDSR), Puddled Transplanted Rice (PTR) and Non-Puddled Transplanted Rice (NPTR) and four irrigation management practices viz., Conventional Irrigation (CI), irrigation for Field Saturation (FS), irrigation on Disappearance of Ponding Water (DPW) and Alternate Wetting Drying (AWD) in three replication. Rice variety Khandagiri was grown for the study. The observation revealed that PTR method of establishment recorded maximum grain yield (5.23 t/ha), straw yield (5.33 t/ha) and harvest index (0.49) which was similar to NPTR with respective values of 4.97 t/ha, 5.27 t/ha and 0.48. Similarly AWD system of irrigation recorded maximum grain yield (5.07 t/ha), Straw yield (5.15 t/ha) and harvest index (0.49). Among different combinations, PTR with AWD recorded the highest grain yield (5.78 t/ha), straw yield (5.77 t/ha) and harvest index (0.51). However, NPTR with AWD recorded minimum water use (13500 m3/ha) with water productivity of 0.38 kg/m3. DSR with AWD recorded the lowest cost of production (35567 Rs/ha) but PTR with AWD recorded the highest gross return (97668 Rs/ha), net return (55005 Rs/ha) and B-C ratio (1.49).
