Abstract: The field experiments were conducted during 2015-16 and 2016-17 at Norman E. Borlaug Crop Research Center, Pantnagar G.B Pant University of Agriculture & Technology, Pantnagar, U.S. Nagar (Uttarakhand) India, to study crop intensification and establishment techniques to enhance productivity under irrigated rice- wheat system. Total input energy (55964 MJ/ha) and total output energy (1381739 and 1179456 MJ/ha), net energy (1326075 and 1123791 MJ/ha) and energy use efficiency (24.82 MJ/ha and 22.47 MJ/ha) during 2015-16 and 2016-17, respectively were estimated to be the highest with treatment T9.The treatment T1 [Rice (TPR) – Wheat] recorded the highest energy intensiveness (0.664 and 0.651 MJ/Rs.) while the lowest value was recorded in T2 (0.424 and 0.416 MJ/Rs.) during 2015-16 and 2016-17, respectively. The highest specific energy was recorded in rice-wheat rotation (4095 MJ/ha and 4388 MJ/ha) whereas, the lowest was in T5 (1725 and 1759 MJ/ha) during both the years, respectively. The maximum energy productivity was recorded in T5 (0.596 and 0.585 kg/MJ) during 2015-16 and 2016-17, respectively however it was at par with T4 during 2016-17. On the basis of two year experimentation it may be concluded among different intensification options, rice (DSR)-potato-cowpea was found to be the best in terms of overall system productivity.
