Abstract: A field experiment was initiated at the ICAR-Indian Institute of Rice Research farm in the Kharif season of 2024 on a deep black clayey vertisols (Typic pellustert) at the IIRR Rice Research farm, Hyderabad (17019″ N latitude, 78023″ E longitude, 542 m altitude with mean annual precipitation of 750 mm). The increase in plant height of rice crop with different types of establishment methods Direct seeded Rice (DSR), Transplanted Rice (TP) and System of rice Intensification was to the extent of 4.1, 33.8 and 61.6% respectively over control, number of tiller/squares was to the extent of 18.3, 24.5 and 30.6% respectively over control., panicles square meter was to the extent of 22.5, 42 and 45% respectively over control. Among the rice establishment methods, significantly higher grain yield of rice crop (4.60 t ha-1) was observed with Transplanted Rice (TP) method followed by System of rice Intensification method (4.39 t ha-1) and Direct seeded Rice (DSR) method (4.14 t ha-1) compared to control (2.95 t ha-1). The increase in grain yield (t ha-1) of rice crop with different transplanting methods Direct seeded Rice (DSR), System of rice Intensification and Transplanted Rice (TP) was to the extent of 27.4%, 35.1% and 41.5% respectively over control. Among them, significantly higher straw yield of rice crop (5.28 t ha-1) was observed with values recorded in Transplanted Rice (TP) method followed by Direct seeded Rice (DSR) method (5.50 t ha-1) and System of rice Intensification method (5.28 q ha-1) compared to control (3.93 t ha-1). The increase in straw yield (t ha-1) of rice crop in System of rice Intensification, Direct seeded Rice (DSR) and Transplanted Rice (TP) was to the extent of 7.1%, 11.6% and 17.2% respectively over control.
