Energy Requirements and Performance of Different Soil Tillage Systems on the Yield of Maize Crop

Shafique Q Memon and Nasima Arshad

Here we are presenting a research study on maize production in Islamabad, Pakistan for the season spring-2013. Impact of tillage methods and input-output energy on maize crop yield have been investigated. Input energy consumption and outputs energy gained for maize crop production have also been evaluated. Grain harvest was found maximum under deep tillage compared with conventional and no-till. The total energy was found comparatively higher under deep tillage than that with conventional tillage, while the least in the no-till. Net energy gain was observed highest under deep tillage.
