Abstract :
In order to evaluate the effects of cultivar and planting pattern on soybean seed yield and yield components a split plot experimental design based on completely block design in three replications was carried out during spring in Bay-e-cola Agricultural Research Station with an elevation of 4 m over sea level and average rain fall of 514 mm. There were three cultivars namely: BP, JK and 032 as main plot and six planting patterns namely: 20×5, 20×10, 30×5, 30×10, 40×5, 40×10 cm2 as sub plot. The results obtained showed that maximum 100-seed weight in main stem and minimum number of seed per pod in main stem obtained in JK cultivars and maximum number of pod in main stem obtained in BP. It was observed that seed yield was not significantly affected among the cultivars. The maximum seed yield obtained for 40x10 cm2 pattern with 951.7g.2m2, coinciding with maximum number of pod per plant and seed per pod in main stem. It was also observed that maximum number of pod in main stem obtained at the interaction effects of BP cultivar at 40x10 cm2 where as the minimum number of empty pod in main stem obtained for BP as 30x5 cm2.Maximum seed yield observed at interaction effects of BP and 30x10 cm2
