than farmer practice which helps to increase or record good growth <strong>of</strong> crop than famer<br />

practice. Further, the cost <strong>of</strong> cultivation incurred for normal method <strong>of</strong> cultivation was higher<br />

(53921) compared to mechanized safflower cultivation (45101) leading to higher net returns<br />

(100699) and B:C ratio (3.20) in mechanized plot Comparing the yield and economics <strong>of</strong><br />

cultivation methods, mechanized plot reduced the labour requirement, time <strong>of</strong> operation and<br />

cultivation cost in turn resulted higher benefits.<br />

The energy use efficiency in mechanized plot (0.56kg/MJ) was higher than normal plot (0.27<br />

kg/MJ). This lead to saving <strong>of</strong> 17 labour / ha and saved 35hrs time period/ha through<br />

selective mechanization <strong>of</strong> important operations. The results were in agreement with the<br />

findings <strong>of</strong> SaeedFirouzi and HashemAminpanah (2012) who reported that Energy output –<br />

input ratio, specific energy, energy productivity, and net energy gain computed were 3.93,<br />

4.74 MJ/kg, in semi-mechanized groundnut production.<br />
