in order to investigate the competitive effects of wild mustard on yield and yield components of wheat cultivars, field experiments was conducted in gorgan reaserch station during 2010-2012 growing seasons. the experiments were laid out in four replicated, factorial arranged rcb design. factors of the experiments included five different densities of wild mustard (0, 4, 8, 16 and 32 plants.m-2) ...

Lodging is one of the most important factors that affect wheat final yield. Emmer [Triticum turgidum subsp. dicoccum (Schrank ex Schübl.) Thell.] a likely gene source to improve durum [T. L. (Desf.) Husn.]; however, it highly susceptible lodging. The genetic studies traits related lodging in crosses × emmer remains largely understudied. Here, we used progenies (six generations) derived from two...

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...

for determination of economic damage threshold of four wheat (triticum aestivum l.) cultivars in different densities of wild mustard (sinapis arvensis l.), experiments were conducted at agricultural research station gorgan during 2010-2012. the experimental design consisted of four randomized complete blocks in a factorial arrangement. the treatments comprised of factorial combination of wild m...

introduction integrated weed management is based on combination of several management methods, while reducing the rate of the use of herbicides, will result in efficient management and sustainable weed control. ability of crop tolerance and prevent weed growth are two important traits in weed competition. an appropriate and suitable cultivar, has high yield potential in the presence of weed and...

the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...
