Abstract
In order to comparison of planting methods on yield and yield components in low irrigation conditions, An experiment was established during 2011-2013 at research farm of Agricultural and Natural Resourses Reserch Center of Markazi Province. Treatments were comparised in Split – Split plot desgine experiment with 3 replications.Tree Irrigation treatments namely: a1-Complet irrigation, a2-cutting off irrigation 20 days after pollination stage and a3-cutting off irrigation after pollination stage. Sub plots were b1- planting wheat 2 rows on a bed ,b2- planting wheat 3 rows on a bed,b3- plain planting and b4- wheat planting by using deep planter. Seed population of c1-350 seeds per m 2 and c2- 450 seeds per m 2 considered as sub-sub plots. Calibration of grain drillers was down on basis of weigh of 1000 grains. Yield and yield components were measured at 2 years . Results of this experiment showed cutting off irrigation after pollination reduce strongly grain yield. If the irrigation is banned 20 days after pollination, 2 rows on a bed and deep planting do not reduce yield and yield components in comparison of complete irrigation(p0.01). However because of less water consumption, deep planting method is recommended regardless irrigation mehods. The effect of seed population was not significant on yield and yield components(p0.05).
