Abstract

Introduction There are many methods to deal with salinity, one of which is less costly and more practical seed priming. Seed prime with different methods with mycorrhiza fungi can be used to improve the deposition of seeds and ultimately yield in saline lands. According to available reports, priming seeds are better placed in environmental stress conditions, such as salinity, and produce higher plantings. Priming increases rooting and increases the yield in corn by 14%. The seedling growth rate was seven days earlier than the non-prime. Plants that are inoculated with mycorrhiza will increase growth and yield and maintain the osmotic potential and ionic balance to a normal level and cause resistance to stress conditions. Materials and methods This research was carried out during two years 2014 and 2015 in two locations in the province of Khouzestan, Gotvand city, with an altitude of 76 meters above sea level and the coordinates of 32 degrees north latitude and 48 degrees east longitude. The experimental design was factorial based on randomized complete block design with three replications on maize hybrid NS64. The concentration of Salicylic acid 0. 5 mM within 14 hours, osmopriming with NaCl solution at a concentration of 2 dS. m-1 within 22 hours, tap water within 18 hours were selected as the best combination of on-farm seed priming. The mycorrhiza fungus was taken in strips under the seeds of 20 g. m-2. Analysis of variance was done using the PROC GLM procedure of the SAS 9. 1 (SAS Institute, Cary, NC, USA). Results and discussion Results showed that all traits in both years and places inoculation with mycorrhiza and priming with Salicylic acid, tap water and NaCl solution to the non-inoculate and non-prime increasing significantly and between inoculation with mycorrhiza and Prime treatments, inoculation with mycorrhiza and prime with Salicylic acid in both place have better condition. Inoculated with mycorrhiza and priming with Salicylic acid in saline place increases the Leaf area index in the Tasseling, number of seeds per ear, 1000-kernal weight, yield, biological yield, Harvest index, the amount of 26. 5, 42, 15. 5, 62. 5, 49. 2, 9. 3 percent than non-inoculation with mycorrhiza and not prime. The difference between inoculation with mycorrhiza and Salicylic acid treatment and noninoculation with mycorrhiza and non-prime in saline place compared to non-saline place in all traits was higher. Conclusion The results showed that application of inoculation with mycorrhiza to non-inoculation and seed priming compared to control (Non-primed) in all measured traits under both saline and non-saline environments were superior in both years. Priming of maize seeds with Salicylic acid (0. 5 mM for 14 hours) was superior to other pretreatments. Under salinity without prime application and inoculum mycorrhiza (control) the amount of number of seeds per ear (212), 1000-grain weight (210 g), grain yield (2826 kg. ha-1) were measured, that application of priming increased all traits and the highest increase was observed in Salicylic acid treatment, which increased grain number in ear (34. 4%), 1000-grain weight (10. 9%), grain yield (48. 7%) compared with not used prime and inoculation with mycorrhiza (control). Inoculation with mycorrhiza increased the number of seeds per ear (19. 8%), 1000-grain weight (4. 2%), grain yield (23. 9%) compared with lack of prime application and inoculation with mycorrhiza (control). Interaction of seed priming and inoculation with mycorrhiza increased all traits. The highest increase was observed in Salicylic acid priming treatments and inoculation with mycorrhiza that increased number of seeds per ear (42. 4%), 1000-grain weight (15. 7%), grain yield (62. 9%) than lack of prime and inoculation with mycorrhiza (control). In the first year, in comparison to the second year, all measured traits increased due to the favorable temperature and number of sunny hours for growing and inoculation of flowers and filling of grain. Consequently, in both saline and non-saline environment, inoculation with mycorrhiza and prime with Salicylic acid is suggested as a method for improving crop cultivation of the NS640 cultivar.
