black seed is one of important ancient medicinal plants with various properties in traditional medicine. in order to evaluate microelements (fe and zn) effects on seed yield and yield components of black seed in salinity stress, a complete block design with three replications was conducted in esfahan agricultural and natural resources center during 2013-2014. three water salinity treatments wer...

This paper proposes new adaptive structuring elements in the framework of mathematical morphology. These structuring elements (SEs) have a fixed size but they adapt their shape to the image content by choosing, recursively, similar pixels in gray-scale, with regard to the seed pixel. These new SEs are called region growing structuring elements (REGSEs). Then, we introduce an original method to ...

in order to the effects of macronutrients  and micronutrients on morphological traits and yields of rice, an examination as factorial in random complete block design and 3 replicate in galoogah region during the year of 2014 conducted. the treatments of nutrients were microelements, microelements, and the mixture of microelements, macro elements and control. the results showed the treatments ha...

In terms of conceptual structures theory, the objective of our project is the development of a pattern directed inference systemm7]. It is to operate over conceptual graph terms extended to express constraints on the referent values, and the matching mechanism is to combine order sorted uniication with the action of a constraint solver. This combination leverages type representation technology ...

The use of renewable resources and inputs is one of the fundamental principles of sustainable agriculture that enables maximum crop productivity and minimal environmental risk. Nutrient management may be achieved by the involvement of organic sources, bio-fertilizers, and micro-nutrients. Indiscriminate use of chemical fertilizers to achieve high yield and to compensate for lack of nutrients an...

the study was designed to evaluate the impact of rhizobium bacteria and mycorrhizal fungi and iron sulfate was performed on chickpea plants. treatments rhizobium bacteria (inoculated and non-inoculated), mycorrhizal fungi (glomus mosseae, glomus intraradices and non-inoculated) and various amounts of iron sulfate fertilizer (0, 40 and 80 kg per hectare) with a factorial experiment in a randomiz...

abstract: iran is considered number one producer of pomegranate throughout the world. the oil extracted from pomegranate seed is considered to have great medical and nutritional values, therefore the study is concerned with this unique and valuable oil specially its chemical attributes. five different varieties of pomegranate were obtained from saveh pomegranate research institute. the seeds we...

introduction: providing the nutritional requirements of agricultural crops by non-chemical resources is a new approach in the organic farming that has attracted the attention of both the researchers and the consumers in recent years. therefore, it is highly important to find new fertilizer resources that are both economically able to provide the nutritional needs of the crop plants and have no ...

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...
