Weeds are a major constraint to the success of dry-seeded rice (DSR). The main means of managing these in a DSR system is through chemical weed control using herbicides. However, the use of herbicides alone may not be sustainable in the long term. Approaches that aim for high crop competitiveness therefore need to be exploited. One such approach is the use of high rice seeding rates. Experiment...

The aim of the present study was to investigate the effects of bee pollination of buckwheat crops on the seed productivity and plant development. Six plots each 4 m2 in size were arranged in a buckwheat field. Four plots in the field were isolated by a net. Nucs with bees were placed in two of the plots (one per plot). Plant productivity, height of plants and number of branches per marked plant...

in order to investigate the efficacy of split, reduced and whole rates of oxyfluorfen in controlling redroot pigweed (amarnthus retroflexus) and also to evaluate possible soybean (glycine max) injuries a experiment was conducted in research greenhouses of karaj collage of agriculture, university of tehran in 2005. treatments included oxyfluorfen doses at 0.25, 0.5, 0.75 and 1 l/ha in one stage ...

Irrigated rapeseed (Brassica napus L.) cultivation is currently expanding in rotation with winter cereals in Iran where its reproductive growth is often exposed to water deficit in many parts, particularly in the south. A two growing seasons (2006-2008) field experiment was conducted at the Experimental Research Center, Shiraz University to study the effects of water stress at different growth ...
