ABSTRACT
This study was conducted at the experimental site in Islamabad, Pakistan, in spring season 2013 (March – July). A randomized complete block design with three treatments and replicated thrice were used in this study, fertilizers were evaluated on the basis of yield, input/output energy of maize crop. NPK had the maximum output energy gain as compared to cow manure and control treatment gave the lowest output energy. Cow manure used high energy as compared to NPK and control. The results further revealed that other NPK fertilizer treatments were affected by the high input costs thus maximum benefits were achieved. It is interesting to note that the NPK treatment appeared to be the best for all farmyard manure and control plots.
