dc.description.abstractPrecision land leveling is the foremost step for judicious use of water and laser land leveler is one such device which could promote efficient utilization of water. So, the present study was conducted at College of Agricultural Engineering and Technology, Junagadh Agriculture University, Junagadh to evaluate the performance of the laser land leveler for land leveling in grading operation and to investigate the effect of laser land leveler on soil properties like soil moisture content and speed of operation, fuel consumption, effective field capacity, theoretical field capacity, field efficiency and cost of operation. Also the effect of laser land leveler on seasonal depth of irrigation, crop parameters of groundnut and irrigation efficiency. The standard deviation of reduced levels after leveling was 5.51 cm and 2,29 cm using the leveler blade and laser land leveler respectively, which was 23.11 percent more than the leveler blade The performance of a laser land leveler was compared with leveler blade for seedbed preparation under a groundnut (Arachis hypogaea L.) crop rotation. The study comprised two treatments with fifteen replications with Large Plot Technique Design with fifteen replications. The two leveling treatments consisted of leveler blade (Ti) and laser land leveler (T2). The operating speed of tractor achieved with laser land leveler was 2.96 km h-i, with 3.1 lit h-i, fuel consumption, 69.53 percent field efficiency while with leveler blade it was 4.68 km h-i, 2.8 lit h-i and 74.35 percent. The seasonal depth of irrigation of laser land leveler and leveler blade was found (800 mm) .The treatments showed significant crop yield (947.94 kg ha-i), harvesting index (25.08 percent) and water use efficiency was (1.19 kg ha-i mm-i) in laser land leveler that were higher than that of leveler blade 740.03 kg ha-i, 18.22 percent and 0.93 kg ha ' mm-i respectively). Operational cost for laser land leveler (2249.57 ? ha-i) were than that of the leveler blade (756.21 ? ha-i) and higher benefit: cost ratio (B: C ratio) (1.58) was observed in laser land leveler which was (1.30) for leveler blade. 11en_US
