Abstract
Effects of different soil tillage and sowing systems (Conventional Soil Tillage – CST: Moldboard plough + gobble disc + disk harrow + harrow + sowing machine; Reduced Soil Tillage – RST: rototiller-combined soil tillage machine + sowing machine; Ridge Sowing – RS: gobble disc + ridge-sowing machine; Direct Sowing – DS – no-till) on plant development and emergence traits of second-crop soybean were investigated in this study under Antalya provincial conditions. Experiments were conducted over the experimental fields of Aksu Branch of Bati Akdeniz Agricultural Research Institute for 3 years (2013, 2014, 2015) as a fixed experiment. The number of days to 50% emergence, number of days to 50% flowering, plant height, number of pods per plant, the first pod height, number of plants per m2, 1000-seed weight and yield were considered as plant development parameters. Mean emergence time, germination rate index, emergence ratio, space ratio, tillering ratio and acceptable plant spacing ratio were considered as plant emergence parameters. Different soil tillage and sowing systems generally had significant effects on investigated traits at p<0.01 and p<0.05 levels.
