Evaluation Of Yield Different Soybean Varieties In Spring And Aestival Cultivation

摘要

In order to determine the difficult soybean varieties yield in spring and aestival cultivation and evaluation ofcultivar adaptability for 2 sowing season in mogan region .in this experiment studied 2 factor: cultivation seasonand varieties. Cultivation season includ spring and aestival. varieties factor include 14 varieties; Sahar, Linford,Hobbit*Williams, Ronack*Williams, DPX, Dawis*Williams, BP, JK Clarck, 032, 033, Zan, Williams, L17.Statistical split plot design in randomized complete block design model and tree replication was conductedduring 2007-2008 growing season at the moghan agricultural research center in 12 km aslanduz road parsabadcity in Ardabil province. Statistical analysis in first year of experiment of revaluated characters showed finallyseed yield; 4070, 3383and 3367kg/ha in spring cultivation was in Zan, BP and Clarck var. and BP, L17,Dawis*Williams varieties were high yield; 2783, 2717 and 2637 kg /ha in aestival cultivation. Final seed yieldwas Zan, Linford and BP varieties in spring cultivation obtained high yield; 4183, 4027 and 3877 kg/ha insecondary year experiment. Also in aestival cultivation the doing after cereal harvesting in moghan region. Finalseed yield were BP 2865 kg/ha Williams 2833kg/ha and L17 2823 kg/Result of combination analysis ofvariance yield showed that cultivation season significant effect have on different varieties yield. BP, Zan andWilliams 3459, 3323 and 3311 kg/ha were high yield varieties in this experiment in duration 2007-2008. Finallyseed yield was Zan, Linford; 4276, 4105 kg/ha in spring cultivation season duration 2007-2008. The highestseed yield; 2974 and 2920kg/ha obtained from BP and L17 varieties in aestival season the lowest seed yieldobtained.
