Abstract:

In this study, the effects of four different tillage systems (GT: mouldboard plough+disc harrow+planting KT1: chisel+disc harrow+planting KT2: rotovator+planting AE: no till planting] on soil physical properties, plant emergence characteristics (mean emergence dates, emerged rate index, percentage of emerged seedling) and wheat yield components were investigated at wheat production in Sivas province. The highest moisture content value was found in AE system for 0-15 cm and 15-30 cm soil depths than the other conventional tillage systems. The highest soil bulk density and penetration resistance were found in AE system. According to wheat emergence characteristics the percentage of emerged seedling for AE, KT1, KT2 and GT tillage systems varied as 85.00%, 71.11%, 83.89% and 87.20%, respectively. The highest percentage of emerged seedling (PE) was found in GT system. As a result of this study, the highest wheat yield was found as 330 kg da-1 in GT system, whereas, the lowest wheat yield was found as 293 kg da-1 in AE system. For among the soil tillage systems, the plant length, spike numbers per square meter and the kernel weight per spike were higher in KT2 conservational system than AE and KT1 systems.
