مقایسه عملکرد برخی از ارقام برنج در شرایط آبیاری با آب شور رودخانه قزل اوزن به روش کشت مستقیم

n order to identify rice different varieties tolerance to salt stress Experiment using that 4-cultivars seeds 9 cultivars, namely Iran Gerdeh (local cultivar), Ali Kazemi, Firuzan ,Sazandegi, And 5 cultivars External and
sent from IRRI with names h1،h2،h3،h4،h5 In conditions Saline Irrigation Quzel Ozan River [Salinity range 4.46 to 6.29 (ds / m)] In the format of randomized complete block design And three replications For each treatment Mahneshan in the city of Zanjan Province in 1392 was conducted. First agricultural preparation of land, Disinfected seeds, Style to heavy seeds, Soaking and germination of seeds, The conventional method Proceeding of hand planting seeds (Direct seeding) became. In this study it was found that salinity has significant effects on yield and yield components of nine varieties cultivated in four varieties arrived the final stage of the four cultivars Include:1- Ali Kazemi,2- gerdeh,3- Firuzan and 4- Sazandegi. Analysis of variance showed that, except for the yield and empty grain number were not statistically significant, panicle length, significant at five percent level, and other functional components Include number of leaves, tiller fertile the grain ,grain length, grain width, grain full , hundred seed weight, flowering time and plant height were statistically significant differences in 1% probability level.
