this study carried out in a factorial layout on completely randomaized block design with three replications, to evaluate the above- and below- ground competition between sesame (sesamum indicum) and pigweed (amaranthus retroflexus), and their impacts on sesame yield and yield component. the experimental treatments were all combination of crop-weed competition (shoot competition, root competitio...

Overuse of different chemical fertilizers is one of the causes for the degradation of environment and soil. Biological fertilizers are the newest and most technically advanced way of supplying mineral nutrients to crops. Compared to chemical fertilizers, their supply nutrient for plant needs, minimizes leaching, and therefore improves fertilizer use efficiency. Vermicompost is an organic compou...

in a sustainable agriculture system, application of the fertilizers which are nature friendly and suitable for plants is essential. this becomes more important when dealing with medicinal plants. therefore, a factorial experiment in a randomized complete block design with three replications was set up in the 2012-2013 on nigella sativa l. treatments were nano­fertilizer (pharmks®) (at 2 levels ...

abstract biofertilizers are one of the main sources to supply nutrient elements for plants in sustainable agriculture. in order to evaluate the effects of biofertilizers and chemical fertilizers on cumin (cuminum cyminum) as a medicinal plant a field experiment was conducted in the research farm of faculty of agriculture, ferdowsi university of mashhad in a randomized complete block design with...

identification of morphological, phenological and yield characteristics of genotypes is important in order to collect necessary information for available varieties and as a result selection of one or more specific traits. in this study, 73 kabuli chickpea genotypes from pulses seed bank of research center for plant sciences, ferdowsi university of mashhad, were planted in irrigated conditions a...

designing breeding programs for winter rapeseed (brassica napus l.) cultivars with improved seed and oil yields requires information about the genetic variability of traits. in this study, 28 winter rapeseed cultivars were evaluated for genetic variation and relationships between 11 agro-morphological characters during 2010 and 2011. cultivars and cultivar × year interaction showed significant ...
