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 indicum L.) farming as a second crop after harvesting lentil in southeastern region in Turkey. Toward this aim, four different soil tillage 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 and some of plan properties at southeastern part of Turkey.The experiment was carried out in research area of faculty of agriculture, Diyarbakir, Turkey in 2014 crop season. The study was designed in accordance with the randomized block design and carried out in three replications. The Results showed that seed yield and weeds density were positively affected 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 not found statistically effect on protein and oil rate.
