Response to grain yield in different varieties of maize (Zea mays L.) In soil salinity in the Astara region

To study the effect of salinity experiment was performed in Astara region. Cultivars included cultivated in two pieces of land in Astara: one with normal soil and the other with salty soil. Maize cultivars were experimented in three replications on the basis of randomized complete block design. During the experiment, yield characteristics such as ear length, number of rows in ear, Number of grains per row, Number of grains per ear, Biomass per plant, Biological yield in plot and Grain yield in plots were measured. In Saline conditions, the maximum ear length was seen in KSC689; which with other genotypes was difference significant. In The number of rows per ear in both normal and salt stress, a significant difference was observed between genotypes. The minimum number of rows per ear was observed in SC604. Grain weight per ear showed significant difference. Maximum grain weight in ear in normal conditions was observed in S. C704; that with all other varieties showed significant difference. The highest yield was observed in normal conditions in S. C704, that with KSC689, KSC647, SC301 and SC540 showed no significant difference. Lowest yield in saline conditions was observed in SC301.
