تاثیر گیاه پوششی سورگوم بر جمعیت علفهای هرز و عملکرد گوجه فرنگی

The use of integrated weed management techniques to reduce the use of herbicides and increase crop yield is
taken into consideration. In order to investigate the effect of sorghum cover crop on tomatoes in 2013 as a
pilot randomized complete block design with four replications at the Agricultural Research Station, of Shiraz
University. Treatments include: 1- cultivated tomato weeding (control), 2- grown tomatoes without weeding
grass weeds, 3- cut cover crop of sorghum at a height of 30 cm, 4- cutting cover crop of sorghum at a height
of 50 cm, 5- applying herbicide Gallant Supper (grass herbicide) on sorghum plant height of 30 cm 6-
Gallant Supper on sorghum plant height was 50 cm. The results showed that the maximum yield of tomato
mulch and herbicide treated at a height of 50 cm above the level of 27/145 tons per hectare, compared to
control was the 4/41 show the percentage increase relative to the control. Sorghum could cover crop
treatments compared to control weeds (no weeding) suppressed. The lowest weed dry biomass at 30 and 50
cm in height mulch treatment discontinuation were observed with herbicide. Generally stated, the use of
cover crop research and development, integrated management of weeds is a good way to control.
