Effects of tillage systems on second crop sesame (sesamum indicum L.) yield and weed density

Abstract

The aim of this research was to define conventional (CT) and conservation tillage systems in sesame (Sesamum indicumL.) farming as a second crop after harvesting lentil in southeastern region in Turkey. Toward this aim, four different soiltillage methods namely, moldboard plough + disc harrow + float +seeding (CT), disc harrow plus+ float + seeding (RT1),cultivator +float+ seeding (RT2) and no-tillage (NT) (seeding by direct drill) were examined on yield of sesame andsome of plan properties at southeastern part of Turkey.The experiment was carried out in research area of faculty ofagriculture, Diyarbakir, Turkey in 2014 crop season. The study was designed in accordance with the randomized blockdesign and carried out in three replications. The Results showed that seed yield and weeds density were positivelyaffected by the tillage methods. The increase in the seed yield observed at Conservation tillage while decrease in the-1 weeds population. The highest yield value was found from CT methods (1623.3 kg ha ). The tillage methods were notfound statistically effect on protein and oil rate.
