| الوصف: | To assess energy use efficiency of hybrids maize as influenced by tillage methods and plant density. A field experiment was carried out at research field of National Maize Research Program (NMRP), Rampur, Chitwan, Nepal during winter season of 2015/16. The experiment was laid out in strip-split plot design comprising two hybrids as horizontal factor (Rampur hybrid 4 and Rampur hybrid 6), two tillage methods as vertical factors (zero and conventional tillage) and four plant populations as sub-sub plot factors (55,555, 69,444, 85,470 and 1,01,010 plants ha-1). Zero tillage recorded significantly higher energy output and net energy balance (238.98 and 217.48 MJ ha-1) as compared to conventional tillage (193.65 and 172.22 MJ ha-1, respectively). Similarly, the plant population of 85 thousand plants ha-1 recorded significantly higher energy output and net energy balance (233.98 and 212.45 thousand MJ ha-1) than 55 (184.10 and 162.87 thousand MJ ha-1) but remained at par with 69 (206.63 and 185.24 thousand MJ ha-1) and 101 thousand plants ha-1 (240.55 and 218.83 thousand MJ ha-1).
