تاثیر پرایمینگ و تداخل علف های هرز روی عملکرد و اجزای عملکرد توده‌های هندوانه بذری (Citrullus‌ Lunatus)

In order to evaluate the effect of priming and Weeds interference on yield and yield components of seed lots of Seed Watermelon (Citrullus Lunatus) an experiment in Factorial design with three factors based on complete block design with three replications was conducted in Research farm of Faculty of Agriculture of Ferdowsi University of Mashhad in May-2012. First factor included three seed lots of Seedy Watermelon (Kalaleh, Neishabour and Dashtak), Second factor included Priming in two levels (primed and non primed seeds) and third factor included the interference of weeds in two levels (contol and lack of control of weeds). Results of variation analysis showed that the effect of weeds interference on was significant for all traits. while the effect of priming was significant in thousand cerenal weight. But wasn’t significant on the other measurement treatments. Interaction and effect of 3-dimensional fiqure of priming and weed on yield and total Dry matter was significant different. the cultivar of Neishabour also was preferred approximately in all treatments rather other cultivars.
