Intercropping and biological control of weeds Год выпуска: 2013Автор: Ali Reza Daraeimofrad,Maryam Ahmadifard and Khosro AziziИздательство: LAP Lambert Academic PublishingСтраниц: 76ISBN: 9783659454585Описание This experiment was conducted in college of agriculture, lorestan university, and khorram abad – Iran, to study effect of barley (Hordeum vulgare L.) intercropping and sole cropping with narbon vetch (Vicia narbonesis L.) on dynamic of weeds population in year crop 2006 – 2007. There were 5 levels of seed contribution, sole cropping of narbon vetch, 75% narbon vetch + 25% barley, 50% narbon vetch + 50% barley, 25% narbon vetch + 75% barley and barley sole cropping and 2 levels of weeds: controlled and interference. This experiment was conducted by in rows replacement series technique in the form of factorial in RCBD with 3 replications. Results showed that interaction of weed levels and intercropping levels was significant and the lowest number of weeds and weight of weeds occurred at 75% narbon vetch + 25% barley equal to (14.3 weeds/m2 and 6.76 g/m2) combination and the highest one occurred at barley sole cropping .
