| Abstract: |
| This research was carried out to evaluate the effect of raised bed planting method on the production of irrigated wheat of Sivand variety in Alborz province. The experiment was carried out in the form of split plots and in the form of a randomized complete block design in three replications. The main plots included the amount of seed consumption at three levels: S1)100, S2)130 and S3)160 kilograms per hectare. The sub-plots included planting methods in three levels, M1) Planting seeds on raised beds with a seed drill equipped with Fertilizer furrow opener, M2) Planting seeds on raised beds with a seed drill equipped with a fertilizer band release system on the soil (without fertilizer furrow opener) and M3)Planting seeds on conventional short beds with seed drill. The results showed that planting wheat on raised beds instead of the conventional short beds increased water consumption and water productivity by 5% and 2%, respectively. The highest and lowest wheat grains of 5571 and 5208 kg/ha were obtained from treatments M1S3 and M3S3 (control), respectively. In M2 removing the fertilizer furrow opener and pouring a strip of fertilizer on the soil surface had no negative effect on the grain yield. Using raised bed planting method instead of M3 increased the net income of farmers by 81, 11 and 11$/ha due to the reduction of water consumption, increase of grain and straw yield respectively. In general, for the cultivation of irrigated wheat in non-saline lands, the use of raised bed planting method is suggested. |
