ABSTRACT

Field 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 1^st June through 15^th August. First June or 15^th June planted soybean produced significantly higher yield over late sowing. Growth and yield components studied decreased significantly as sowing was delayed beyond 15^th 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 1^st June to 15^th by planting Bossier variety.
