Oad 1200221Field experiment was conducted during summer, 1997, 1998 and 1999 at Z.A. Bhutto Agricultural College, Dokri, Larkana, Pakistan. Four soybean cultivars i.e., Bossier, Hampton, Improved Pelican and Clerk-63 were planted at 15 days interval during 1st June through 15th August. First June or 15th June planted soybean produced significantly higher yield over late sowing. Growth and yield components studied decreased significantly as sowing was delayed beyond 15th June. Among four cultivars tried Bossier gave significantly greater yield as compared to rest of the cultivars. Seasonal effect was also significant for all characters studied, 1999 season displayed more yield than did 1997 and 1998 seasons respectively. It is recommended that soybean should be cultivated from 1st June to 15th by planting Bossier variety.]]>Dunphy, E.J., J.J. Janway and D.E.
