Soybean (Glycine max) is a major crop grown in agroforestry systems in northern India during kharif season. However, reduction in soybean yield under close canopy and partially open conditions in comparison to fully open condition becomes a major factor in its adaptation. The present study quantified the growth and yield attributes of various soybean varieties in agroforestry systems (Tectona grandis and Dalbergia sissoo) in terai region of Uttarakhand. The study recorded higher plant height of G. max in D. sissoo based agroforestry system. However, among tested soybean varieties, var. PK 1042 recorded higher plant height. The higher biological yield was recorded in control (6617 ka ha-1) and among tested varieties, it was recorded higher in var. PK 1241 (5589 kg ha-1). Likewise, higher protein content was also observed in the control (39.22%), and among varieties, var. PK 1029 recorded higher protein content (38.86%). Hence, it is concluded that D. sissoo and T. grandis based agroforestry systems are the best systems for growth and production of soybean in terms of yield and quality.
