Effect of Planting Methods and Various Seed Rates On Chikpea Yield in Dryland Areas

Global population is increasing and needs to improve crop production methods. Chikpea is one of the important cereals in Iran due to its potential of income benefit, land improvement and rotation with other crops. Production methods in current situation is mostly traditional. Planting opration is also traditional with broadcasting seeds in the dryland areas of Iran and no investigation conducted to change or improve the system. The experiment was conducted in Maragheh and Sararood research stations during the 1996-1999 growing seasons. In this study the possibility to use appropriate machines was investigated in two major dryland regions of Maragheh and Kermanshah. Therefore the traditional method (hand seeding) was compared to two mechanised methods using drill, and row crop planter in three seed rates of 50, 75 and 100 Kg/ha. The treatments were evaluated in a strip plot design with vertical factor of planting methods and horizontal factor of seed rates. In this research planting depth, seed space and rows, crop height, branch per plant, pod per branch, seed per pod, canopy height and seed yield were evaluated. Statistical analysis indicated that planting by drill at 75 kg/ha seed rate demonstrated acceptable performance in both regions. Therefore the results proved that, it was possible to mechanise chikpea planting methods enabling mechanical weed control, as well as mechanised harvesting in next stage.
