Seed priming effect on the number of rows per ear, grain weight and economic yield corn in Sistan region

Abstract

To study the effect of seed priming on maize under drought stress experiment was split plot based on randomized complete block in three replications In 2012 the Research Center Zahak Was conducted. Subplots seed priming with potassium nitrate solution in five levels (control, 0.5%, 1%, 1.5% and 2%) and three levels of stress as a major factor (control, drought stress at vegetative stage (5 leaflets) to enter the reproductive phase, drought stress at reproductive stage until harvest), respectively. Maximum number of rows per ear on average compared to non-stress conditions (14.27) was observed. The results of the analysis of variance showed that the priming effect on the number of rows per ear was statistically significant at the one percent level. So that a comparison can be inferred from the table, the highest number of seeds in a row, the concentration of potassium nitrate (15.04), respectively. So that the comparison is taken out of Length of ear in terms of highest stress (20.92 cm) was observed. So that the comparison is taken out one of the highest concentrations of nitrate in Length of ear (22.05 cm), respectively. So that the comparison is taken out of Length of ear in terms of highest stress (225.67 mg) was observed. So that the comparison is taken out top thousand seed weight percent potassium nitrate at a concentration (269.7 g), respectively. So that the comparison is taken out of the economic performance of the highest non-stress conditions (2.28 t/ha) was observed. So that the comparison is taken out of the economic performance of the highest concentration of potassium nitrate (20.3 ton/ ha), respectively.
