Effect of Pre and Post Emergence Herbicides and Their Combination Under Hydropriming on Weed Control and Yield of Sesame Sesamum indicum L Samane Vafaei s vafaei @ yahoo com September 19 2011 Department of Agronomy and Plant Breeding Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Persian Supervisor Jamshid Razmjoo Krazmjoo@cc iut ac ir AbstractPresence of weeds and their competition with crop is a major factor that cause reduction incrop quality and yield Priming of seed improves seedling establishment and germination andincreases competition ability of crops with weeds In this study the effects of alachlor 3 5 5l ha and trifloralin 1 5 2 5 l h as pre emergence and bentazon 75 1 l ha and haloxyfop 2 3 l ht as post emergence herbicides and their combination along with the effect of seedhydropriming on weed control and growth and yield of sesame were studied at the LavarkReasearch Farm Isfahaan University of Technology Isfahan Iran in 2010 Thirteenherbicide treatments along with weed control free and hand weeded control were evaluatedusing a factorial experiment based on a randomized complete block design with threereplications Hydropriming reduced days from planting to seedling establishment increasedseedling dry weight and the crop grain yield Amaranthus retroflexus Echinochola crus galliand Chenopodium album were dominant weeds The combination of Bentazon and alachlorand bentazon with trifloralin were the most effective treatments in reducing the number ofweeds and increasing the grain yield The interaction between herbicide rate and priming wassignificant for non of the traits However a significant interaction was found betweenpriming and herbicide for the grain yield Hydropriming with pre emergence alachlor 3 5 5l ha trifloralin 1 5 l ha and their combination with haloxyfop increased the grain yield ofsesame Application of 2 5 l ha of trifloralin caused significant damages to sesame crop Application of bentazon with pre emergence herbicides significantly controlled the weeds but it caused substantial damages to sesame crop The lowest seed yield was obtained withthe post emergence herbicides and their combimation The results showed that hydroprimingalone had no effect on weed control but increased the sesame yield In order to effectivelycontrol the weeds in sesame application of alachlor 3 5 5 l ha with trifloralin 1 5 l ha ortheir combination with haloxyfop along with hydropriming should seemingly be practiced Key words Herbicide weed control priming sesamum yeild
