To study the effects of applied nitrogen levels and wild mustard densities on the growth of wheat and wild mustard, a field experiment was conducted at Re-search and Experimental Field of Islamic Azad University of Ahvaz-Iran. The effects of three nitrogen levels namely 90, 150 and 210 kg.ha-1 and four wild mustard densities such as 0, 5, 10 and 15 plants.m-2 were evaluated in split plot arrang...

In order to study the effects of wild mustard competition and different levels of nitrogen on effective traits of wheat yield, this research was conducted in Ahvaz, south west of Iran. The study was consisted of a split plot experiment, on the basis of Randomized Complete Blocks Design with three replications. Different levels of nitrogen (90, 150 and 210 kgN.ha-1) were assigned in the main plo...

to evaluate the effect of different rates of nitrogen fertilizer on competitive ability of canola (okapi cv.) in interference with wild mustard, a split-plot experiment based on a randomized complete block design with 3 replications was carried out at agricultural faculty of bu-ali sina university, in 2008-2009. 4 levels of nitrogen fertilization (100, 150, 200 and 250 kg n ha-1) were assigned ...

in order to study the interaction allelopathic effects of wheat, barley and wild mustard on seed germination and seedling growth, this investigation was conducted in 2009 in two separate experiments. allelopathic effect of four aqueous extracts (0, 2.5, 5 and 10%) of wild mustard on wheat and barley germination was evaluated in the first experiment, based on two randomized completely designs (r...

Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...

a two year field experiment was carried out to evaluate the competitive effects of wild mustard densities growing with rapeseed (cultivar talaye) under different nitrogen rates. treatments were wild mustard densities (0, 10, 20, 30, and 40 plant m-2) and nitrogen (n) rates (0, 50, 100, 150, and 200 kg n ha-1). the factorial set of treatments was arranged into a randomized complete block design ...

to investigate wheat and wild mustard growth and competition to n levels, an experiment was conducted in ramin agriculture and natural resources university of khouzestan, located at 36 km north of ahvaz. treatments included planting wheat solely, wild mustard solely, and intercropping wheat and wild mustard in pots. these combinations were exposed to n levels including 0, 60, 120 and 180 kg.ha-...

A greenhouse experiment was conducted to evaluate the competitive effects of different densities of wild mustardas against rapeseed. The experiment was performed in a randomized complete block design with four replicationsusing replacement series in which wild mustard and rapeseed were respectively planted in different ratios of 4:0, 3:1,2:2, 1:3 and 0:4 plants per pot. Results indicated that t...
