Abstract: An experiment was conducted at Research farm, ICAR- Indian Agricultural Research Institute, New Delhi during 2010-12. The treatment comprised of four land configurations (Flatbed, flatbed with mulch, ridge-furrow, and broadbed-furrow) and three fertility levels (Control, 15 kg N+30 kg P₂O₅/ha and 15kg N+30 kg P₂O₅+PSM/ha) with factorial Randomized block design in green gram crop. The boradbed furrow method of land configuration recorded the highest grain and stover yield whereas among the fertility levels treatment applied with15kg N+30 kg P₂O₅+PSM/ha recorded the highest grain and stover yield. The maximum gross return, net return, net B:C ratio, value: cost ratio and return ₹/ha/day was found with broadbed-furrow closely followed by ridge-furrow whereas flatbed with mulch had minimum gross returns and net return and B:C ratio. Application of 15kg N+30 kg P₂O₅+PSM/ha brought improvement over 15 kg N + 30 kg P₂O₅/ha but both were significant over control in terms of gross return, net return, net B:C ratio, value: cost ratio and return ₹/ha/day. Broadbed-furrow recorded the highest energy output, energy efficiency, energy productivity, and energy intensity while minimum in flatbed with mulch. A dose of 15 kg N+30 kg P₂O₅+PSM/ha proved maximum net energy, energy efficiency, energy productivity, and energy intensity and minimum with control but energy output in the flatbed.
