In this paper, method based on high performance liquid chromatography with fluorescence detection has been suggested to measure aflatoxin in saffron. This method required a simple extraction of aflatoxin using MeOH/H2O (80:20, v/v) and a purification by immunoaffinity column cleanup. Aflatoxin measurement was performed at an emission wavelength of 445 nm and an excitation wavelength of 365 nm. ...

Saffron flowering can be mainly affected by mother corm size and phosphorus content of corm. In order to investigate the effects of mother corms size, organic fertilizers and foliar application on corm yield and phosphorus uptake of saffron (Crocus sativus L.) under control conditions, an experiment was conducted in the growing years of 2012-2013 at Faculty of Agriculture, Ferdowsi University ...

SUBJECT: vermicompost; micro nutrients; replacement corms

Agricultural sector to meet the requests such as a higher yield, less pollution and fulfill consumer demands due to increasing scarcity of resources is under pressure. According to the importance of efficiency in productivity growth, this index can play an important rule, especially in developing countries, for the development of agricultural systems in order to meet these requests. The aim of ...

Saffron (Crocus sativus L.) is one of the most important crops and medicinal plants in Iran. Appropriate application of nutrients has special important role on replacement corm growth and flower yield of saffron. In order to investigate the effects of different levels of soil and foliar nutrients applications by using mixture fertilizer on replacement corm production and flower yield of saffro ...

SUBJECT: fertilization; spraying; replacement corm; stigma of saffron

In order to study and compare chemical and non-chemical methods of weed management in saffron (Crocus sativus) fields, two field experiments were carried out in a randomized completely block design with three replications at Research Field Station of Gonabad during 2009 to 2011. Treatments included cover crops of barely, Mushroom bed mulch, herbicides of haloxyfop R methyl ester (EC10%), iodos ...

SUBJECT: barely; cover crop; mulch; herbicide; hand weeding

With due attention to facilities, and different potentials and sources in agriculture of Torbat Heydarieh city, this region is suitable for cultivation and production of saffron. In this study comparative advantage of saffron production in Torbat Heydarieh investigated using DRC index and policy analysis matrix (PAM) during 2012-13. Also in this study evaluated comparative advantage of saffron ...

The present paper aimed to determine the criteria for understanding climate and ranking factors influencing saffron and assess its impact on Roshtkhoar city of Khorasan Razavi province. The city of Roshtkhar has potential for increasing saffron cultivation; therefore, the main hypothesis during the research was, which climatic factors had the most influence on the cultivation of saffron in the ...

SUBJECT: expert choice; ranking; multi-criteria decision making; climatic factor& element; saffron

Saffron (Crocus sativus L.) is cultivated as spices, medicinal and aromatic plant species. At autumn season, heavy rainfall can cause flooding stress and inhibits growth of saffron. Thus this research was conducted to study the effect of silver ion (as an ethylene inhibitor) on growth of saffron under flooding conditions. The corms of saffron were soaked with one concentration of nano silver ( ...

SUBJECT: root dry weight; corm; root length; flooding stress; nano silver

Mother corm size and nutrient management are the most important factors in relation to nitrogen uptake of saffron (Crocus sativus L.). In order to investigate the effects of mother corms size and type of fertilizer on uptake and use efficiency of nitrogen in Saffron, a field experiment was conducted as factorial layout based on a randomized complete block design with three replications at Facu ...

SUBJECT: chemical fertilizer; organic fertilizer; nitrogen uptake efficiency; replacement corm
