The present study evaluated the effects of different dosages herbicides Oxyfluorfen and Trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. In this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...

a field study was conducted to evaluate the effect of haloxyfop-r-methyl ester doses in different grass weeds in various growing stages in safflower during 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried our as split split plot based on randomized complete block design with three replicates. the main factor, sub factor and sub sub fa...

jimsonweed (datura stramonium l.) is an important weed in bean fields in iran. in order to investigate the effect of density and relative time of emergence of jimsonweed on yield and yield components of chitti bean, a field study based on factorial experiment was conducted at farm bean research national station in khomein in 2006. treatments were chosen to provide four different weed densities ...

in order to study yield and yield components in intercropping bean (phaseolus vulgaris l.) and sweet basil (ocimum basilicum l.) and evaluating effect of intercropping on weed control, a field experiment was conducted at the agricultural research station, ferdowsi university of mashhad during growing season of 2008. treatments: included 1- sole crop of bean 2- sole crop of sweet basil 3- strip ...

in order to study of nitrogen effect on critical period of weed control in sunflower (helianthus annuus l.) in birjand region, a split plot experiment based on randomized complete block design was conducted with 24 treatments and 3 replications in research farm of college of agriculture of birjand university in 2010. the main factor was three levels of nitrogen (0, 100 and 200 kg.ha-1) and the ...

To assess the effect of non chemical management of weed control on forage Sorghum (Sorghum bicolor) a field study was conducted in Varamin, Iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (W1= one time cultivation at 3-leaf stage using a duck foot cultivator, W2<...

The aim of the study was to determine the biomass, abundance and species composition ofweeds, as well as macroelement uptake in potato weeded using mechanical, mechanical–chemical and mechanical control combined with the sowing of living mulches of white mustard,common vetch, Persian clover and tansy phacelia. Abundance and biomass of the weeds was themost effectively limited by the mechanical ...

Allelopathy refers to the chemical inhibition or stimulation of one species by another which could influence on the growth or germination of other plant and used in control of weed in agricultural practices. In this sense in order to study the possibly allelopathic effects of lemon balm, bitter apple and lemon verbena medicinal plants on control of wild mustard weed, a laboratory experiment was...

Adviser: George Gogos Flaming is a thermal weed control method that can kill weeds within or between crop rows using heat. Mechanical cultivation is another weed control method which undercuts weeds between crop rows to kill them. A combination flamer/cultivator implement was designed to take advantage of the good qualities of both flaming and cultivation to provide excellent organic weed contr...
