Abstract

Background and objective: Saffron (Crocus sativus L.) is the most expensive crop in the world. In the recent years researches on this plant has been increased according to regional and national economic importance. Among the various studies on saffron the problem of nutrition is always important. This study was conducted to evaluate and compare the effect of foliar application of chemical, biological and bio-stimulator fertilizers on yield and yield components and also growth and CORMs characteristics of saffron.Material and methods: An Experiment was conducted in a completely randomized block design with four replications in 3- year field of saffron in Dargaz, Khorasan Razavi province from 2010 to 2011. The first factor had 5 levels included biostimulator fertilizer BIOAMINO-PALIS, biostimulator fertilizer Aminolforte, biological fertilizer NITROXIN, chemical fertilizer DALFARD-15, and control (without fertilizer treatment). The second factor had two levels including 1 and 2 times spraying with seven per thousands concentration of each fertilizers treatments. All fertilizer spraying concentration was 7 per thousand. The first spraying on Jun 20, 2010 and the second time after 15 days on June 24, 2011 were done. Measuring growth characteristics and properties of CORM was done in the early May 2011 and measuring yield and yield components was done in the early November 2011.Results: The results showed AMINOL-FORTE have better effect than other fertilizers on dry weight of CORM, number of CORM, number of CORM equal/ higher or under 8 grams, fresh weight of flower, number of flowers, fresh and dry weight of stigma and style per square meter, leaf length as well as fresh and dry weight of leaf.Bioamino-palis and AMINOL-FORTE fertilizer treatments for number of flowers, fresh weight of stigma and style and dry weight of stigma, did not have significant difference. Biological fertilizer NITROXIN had little positive effect on the evaluated traits. The effect of fertilizer DALFARD-15 was the intermediate of biological and biostimulator fertilizers. Two times foliar applications only reduced the number of CORMs weighing less than 8 g per unit area. Interaction of foliar applications levels and fertilizer types did not have significant effect on measured traits.Conclusion: Based on the results biostimulating fertilizers, AMINOL-FORTE and BIOAMINO-PALIS had more significant effects on growth factors, CORMs and performance traits of saffron compared to DALFARD-15 chemical fertilizer, and NITROXIN biological fertilizer. This can be attributed to their amino acids and growth stimulants. AMINOL-FORTE fertilizer increased the soffron stigma yield and CORMs higher weight of 8 grams while BIOAMINO-PALIS only increased stigma performance.Aminol Forte greater impact on CORM weight was associated with a greater impact on growth. On the basis of the results of this experiment, spraying of AMINOL-FORTE is recommended in saffron fields once.
