introduction bean is one of the most important legumes worldwide for direct human consumption and is a rich source of protein and carbohydrates. bean is weak to compete with weed because of the retard growth at the early stages. therefore, weed control at this time plays an important role to gain high priduction. yield crop depends on weed number, and size after germination. weed control depend...

evaluation of weed population and their interference on lentil varieties at different sowing date was investigated in a field experiment in khorramabad during 2005-06 growing season. the experimental design was a randomized complete block in factorial arrangement with 4 replications. the experiment had 3 factors including: planting date at three levels (autumn, winter, and spring) weed interfer...

to investigate the efficiency of eradicane application, using herbigation as compared with conventional method (spraying), concerning weed biomass and density reduction and change in corn grain yield, a factorial experiment was conducted based on randomized complete block design in 2006 at research fields of university of tehran (karaj). eradicane was applied at 4.5 (labeled rate), 3.15 or 5.85...

an experiment was conducted in bandar kyashahr research field in 2002 to evaluate the effects of plant density and planting pattern on weed populations and yield of peanut (arachis hypogaea l.). the experiment was of a randomized complete block design with three replications. a factorial trial with two factors of planting pattern (square and rectangular arrangements) and plant density (3, 5.3, ...

crop residue is a non-chemical method of weed control in agricultural sustainable systems. this research was conducted at the alarogh site of ardabilto evaluate the effect of integrated use of mulch and herbicide on weed emergence and growth in potato in 2007. treatments were four levels herbicide including: (1) paraquat [n,n'-dimethyl-4,4'-bipyridinium dichloride] herbicide as pre-pl...

given the importance of sustainable agricultural development, using non-chemical weed management such as cover crops and decreasing row spacing has an importance in weed control and reducing herbicide use. in order to an experiment was conducted at agricultural research site in agricultural college, university of mohaghegh ardabili in 2011. the experiment done as factorial based on randomized c...

in order to evaluate the effects of crop cultivars and living mulchon sunflower yield and weed control, a field experiment was carried out as factorial arrangement based on a randomized complete block design with three replications in 2013. treatements were sunflower cultivars (‘azargol’, ‘allstar’, ‘farokh’) and weed control treatments (weed-free, weed-infestation and intercropping of fagopyru...
