Among other agronomic factors, planting method is of great significance as it not only determines the proper crop stand establishment but also the production of individual plant through balancing plant to plant competition and facilitating the conversion of light energy to harvest yield of crop. A field experiment was conducted to evaluate the effect of different planting methods on yield and yield components of wheat under semi-arid climatic conditions. Four planting methods; raised bed, ridging, drilling and broadcasting were evaluated. Results revealed that highest number of wheat plants emerged with drill sowing either on beds or flat field. The significant increase in plant height, tillers m-2, grains per spike, 1000-grain weight and grain yield were noted in raised bed planting system compared to all other planting methods. However, tillers m-2, spikelets per spike, grains per spike and 1000-grain weight were statistically similar in ridge sowing and drill sowing methods. The significant (P less than or equal to 0.05) increase in yield was noted by bed planting (24.46%), ridge sowing (20.86%) and drill sowing (17.33%) over conventional method of broadcasting. Raised bed and ridge sowing methods of wheat plantation saved 22.47 and 13.26% irrigation water, respectively over flat sowing either by drilling or broadcasting. The cost of cultivation was lower and net benefit cost ratio was higher in bed planting than conventional method of wheat plantation.
