Energy management in crop production system is an essential component in sustainable agricultural production systems. The aim of study was to evaluate the impact of flat planting (FP), ridge planting (RP) and direct planting (DP) methods under reduced tillage system (RTS) on the energy balances used in silage corn production, planted after winter wheat crop in Potohar region. The study was carried out under complete randomized design (CRD) with three replications at Koont research farm Chakwal, PMAS-Arid Agriculture University, Rawalpindi during 2018 and 2019 crop seasons. Results of this study indicated that the specific energy value of reduced tillage flat planting was calculated as 0.44 MJ-kg-1, ridge planting as 0.40 MJ-kg-1, and direct drilling was calculated as 0.46 MJ-kg-1. Comparing the energy output/input rates, this rate was determined as 9.34 in reduced tillage flat planting, as 10.36 in ridge planting, and as 9.06 in direct drilling. In all methods, it was shown that fertilizer energy had the maximum rate of application among the total input energies. Corn cultivation with ridge sowing is more energy efficient and profitable production technique under rainfed agriculture in Potohar region.
