Abstract

In order to manage cost reduction in saline land under wheat cultivation a research was carried out as a split-plot arranged as a randomized complete block design with three replications. The main factor included three soil moisture percentages during the initial plowing (10, 15 and 20%) and secondary factor was four methods of land preparation and sowings (non application of chisel piler + sowing with flat planter, non application of chisel piler + sowing with furrow planter, application of chisel piler + sowing with flat planter and application of chisel piler + sowing with furrow planter). The results showed that the highest weight and volume of clods were found when non application of chisel piler with 20% soil moisture was applied and the lowest one when chisel piler with 10% soil moisture was applied. The highest seed germination was with application of chisel piler + furrow planter and humidity of 20% and the lowest value was with non application of chisel piler + flat planter and soil moisture of 10%. The highest grain yield was obtained with application of chisel piler + furrow planter by 4593 kg/ha and the lowest value was obtained by 2797 kg/ha under non application of chisel piler and flat planter. In general, the results showed that the use of chisel piler and furrow planter with 20% soil moisture had a positive effect on improving germination, physiological and yield characteristics of wheat in saline lands, and it can be taken into consideration by farmers.
