| Summary: | This research was carred out in “Anbar-e-olom Saline Reasearch Station” in 35 km north of Gorgan, Golestan province at the agronomy year of 1384-85.The experiment was arranged in Split-plot Factorial was in a form of Randomized Complete Blocks Design (RCBD) in 4 replications including the main and secondary factors, on soil Clay Loam, pH8.2 and EC9.2 (dSm-1). The main factor included amounts of Sulphur (0, 500 & 1000 kg/he) and the secondary factors included the two seed size (Small and Large) and 3 genotypes of wheat (Zagros, Desconcido-7 and Kohdasht). Results showed that there was significant differences amounts the treatments and regarding (Sulphur, Seed size and Genotypes) such as, Grain yield, number of fertile stems per square meter, number of grains per spike, weight of kernel, Harvest Index (HI) of spike, HI of plant, weight of spike (gr/m2), number of spikelets per spike. By comparing the characteristics mean it was proved that using 1000 kg/ha sulphur was significant difference in grain yield parameter. Although using of sulphur 500 kg per hectare had effected more than amount not using (without sulphur) but it was not significant difference. Using the two different amounts of seed size (Large and Small) were significant difference with each other. And using of Kohdasht genotype was significant difference in grain yield parameters and as the second, Zagros genotype and as third, Desconcido-7 was significant difference with each other. Also as the reciprocal effects, Sulphur 1000 kg/ha, large seed size and Kohdasht genotype had the most amounts of grain yield and effect. |
