A study on seed water pre-treatment effects on, oil and protein percentage and some of agronomic traits in soybean in Iran

Abstract

To study the Seed Water Pre-Treatment effects on Oil and Protein percentage and some of agronomic traits in Soybean, a research was carried out in Ardebil Islamic Azad University research farm, in 2008. This research was conducted in factorial based on complete block randomized design. One of the Water Pre-Treatment factors was 8, 12, 16 and 20 hours which were soaked in tap water and dried to 30percent moisture. A seed sample was also considered as an observation sample (without pretreatment). The second cultivar factor was Williams and LV (17). Results indicated that there is a significant difference at 1percent level between Water Pre-Treatment durations on Germination percentage, Seedling Weight, grain yield, oil percentage, weight of sub-stems and number of sub-stem. In most traits other than sub-stems weight and number of sub-stems, 8-hour Water PreTreatment provided the best yield. The results to the average comparison table indicated that Williams's cultivar had the most height with 8-hour Water Pre-Treatment. Also, there was a significant difference among cultivars on number of sub-stem and weight of sub-stems at 1percent and in most traits LV (17) had a better yields comparing to the Williams cultivar. Considering the results, see Water Pre-Treatment due to the short growth period and to increase the yield and better green in farm seems to be of significance. Also, 8-hour Seed Water Pre-Treatment is suggested for soybeans.
