The Effects Of Row Spacing On Yield And Yield Components Of Full Season And Double-Cropped Soybean, Sevgi̇ Çalişkan, Mehmet Arslan, İlhan Üremi̇ş, Mehmet Emi̇n Çalişkan

Turkish Journal of Agriculture and Forestry

Compared to full season soybean cropping systems, seed yield reduction is a major concern in double-cropped soybean production systems. This study was conducted at the Research Farm of Mustafa Kemal University, Hatay, Turkey, to determine if it is possible to enhance the yield of both full season and double-cropped soybean by narrowing row spacing. Two soybean cultivars, A3935 and S4240, were planted using row widths of 30, 50, and 70 cm, and twin row (50 25 50 cm) in 2004 and 2005. Seed yield and the other investigated plant parameters of double-cropped soybean were lower compared to full season soybean. …
