Abstract:
To study the effects of irrigation on yield and physiological characteristics of different genotypes soybeans,two soybean cultivars Liaodou 21 and Liaodou 14 were taken as materials,two irrigation levels were applied.The results indicated that 1)The LAI increased and then declined with the growth of soybean,the irrigation increased LAI and shoot biomass in soybean.The RGR decreased gradually as the growth of soybean and showed negative increase at later growth stage.Both genotype and irrigation influenced RGR of soybean,but genotype played a more important role than irrigation.2)The irrigation could enhance pods per plant to promote yield,but the effect of genotype and the interaction effects of irrigation×genotype on soybean yield were not found.Liaodou 14 had more pods per plant than that of Liaodou 21 under the same irrigation condition.3)The irrigation and genotypes had significant effect on soybean yield,Liaodou 14 showed higher yield than that of Liaodou 21 under the same irrigation condition,and irrigation condition showed higher yield than that of non-irrigation with the same variety.Among all of the treatments,Liaodou 14+irrigation had the highest yield,LAI and shoot biomass at 12-16 weeks after emergence.
