摘要

Compared to full season soyabean cropping systems, seed yield reduction is a major concern in double-cropped soyabean 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 soyabean by narrowing row spacing. Two soyabean 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 soyabean were lower compared to full season soyabean. Row spacing had a significant effect on plant height, number of nodes per plant, main-stem pod and seed number, branch pod and seed number, and seed yield in both cropping systems. The highest seed yield (4142.5 kg/ha) averaged over years was obtained from a 50-cm row width in full season soyabean cropping, whereas a 30-cm row width had the highest seed yield (3241.5 kg/ha) in double-cropped soyabean. In full-season soyabean production, a 23% yield increase was recorded when row width was shifted from 70 to 50 cm, and no yield increase was recorded by further narrowing the row width. In double-cropped soyabean, 24.8, 59.5 and 35.6% yield increases were recorded when soyabean was planted in 50 and 30 cm, and twin row width, respectively, instead of a 70-cm row width. The results indicated that yield reductions in double-cropped soyabean production could be alleviated by narrowing the row width in the eastern Mediterranean region..
