چکیده

introduction in recent years, by increasing human knowledge and using different technology on food production, human concerns have increased on safety of food products especially medicinal crops. in order to achieve healthy food production, application of ecological inputs such as organic and biological fertilizers are inevitable. organic fertilizers are fertilizer compounds that contain one or more kinds of organic matter. they can improve the soil ability to hold water and nutrients. they create a beneficial environment for earthworms and microbial organisms that break the soil down into rich, fine humus (motta & magggiore, 2013). compost is organic matter that has been decomposed and recycled as a fertilizer and soil amendment. compost can greatly enhance the physical structure of soil. the addition of compost may provide greater drought resistance and more efficient water utilization. vermicompost is the final product of composting organic material using different types of worms, such as red wigglers or earthworms, to create a homogenized blend of decomposed vegetable and food waste, bedding materials and manure. vermicompost helps store nutrients and keeps them safe from leaching and irrigation, functioning to balance hormones within plant physiology, and adding beneficial biology to soil (raja sekar & karmegan, 2010). mycorrhiza arbuscular fungi are other coexist microorganisms that improves soil fertility, nutrients cycling and agroecosystem health. mycorrhizal fungi are the most abundant organisms in agricultural soils. many researchers have pointed to the positive roles of mycorrhizal fungi on plants growth characteristics. despite of many researches on the effect of organic and biological fertilizers on different crops, information on the effects of these fertilizers for many medicinal plants is scarce, therefore, in this study the effect of simultaneous application of mycorrhiza with compost, vermicompost and sulfural geranole on some quantitative and qualitative characteristics of sesame (sesamum indicum l.) in a low input cropping system was investigated. materials and methods in order to evaluate the effects of simultaneous application of mycorrhiza and organic fertilizers on some quantitative and qualitative characteristics of sesame (sesamum indicum l.), an experiment was conducted based on randomized complete block design with three replications at agricultural research farm, ferdowsi university of mashhad, iran during growing season 2009-2010 growing season. treatments were mycorrhiza (glomus mosseae), mycorrhiza+compost, mycorrhiza+vermicompost, mycorrhiza+organic sulfural geranole, compost, vermicompost, organic sulfural geranole and control (no fertilizer). finally, data analysis was done using sas 9.1 and means were compared by duncan’s multiple range test at 5% level of probability. results and discussion the results showed that the effect of different organic and biological fertilizers were significant on seed yield. seed yield significantly increased by using mycorrhiza in both condition of single and mixed with organic sulfural geranole and vermicompost compared to control treatment. biological yield, in simultaneous application of vermicompost and organic sulfural geranole with mycorrhiza increased significantly compared to separate use of these fertilizers. all study organic fertilizers with mycorrhiza had significant effect on increasing oil content of sesame. seed oil increased in simultaneous application of mycorrhiza and each of compost, vermicompost and organic sulfural geranole compared to separate application of mycorrhiza 12, 13 and 10 percentages, respectively. it seems that mycorrhiza and organic fertilizers improved quantitative and qualitative characteristics of sesame due to provide better conditions to absorption and transportation of nutrient to the plant (hawkes et al., 2008). conclusion in general, the results showed that the simultaneous use of ecological inputs can improve quantitative and qualitative characteristics of plant, moreover, decreased environment risks of chemical inputs and ensure sustainability of production in long time by this approach. acknowledgments we wish to thank vice president for research and technology, ferdowsi university of mashhad, iran for the financial support of the project.

Genetic Divergence in Sesame (sesamum Indicum L.) Landraces Based on Qualitative and Quantitative Traits

Sesame (Sesamum indicum L.) is one of the world’s oldest oil crops and has been cultivated in Asia since ancient times. The breeding potential of the germplasm accessions held in PGRP gene-bank has hardly been exploited to date. This study was carried out to evaluate the phenotypic variability in the local sesame genotypes using 16 qualitative and quantitative traits. A total of 105 sesame acce...
