Abstract
In order to evaluate the effects of organic manure, biological and chemical fertilizers on quantitative and qualitative characteristics of Isabgol, an experiment in a randomized complete block design with 4 replicates was performed at University of Zabol in 2011 crop year. Fertilizers included Vrmicompost (10 t ha-1), manure (20 t ha-1), Biological fertilizer of phosphate-E-barvar 2 (100 g ha-1), Biological fertilizer of phosphate-E- barvar 3 (100 g ha-1), Triple super phosphate (50 Kg ha-1), and control. After harvesting, the seeds were sent to the laboratory and the viability of seed was examined. Results showed that the effect of fertilizers on root length, fresh and dry weight of root, spike length, number of spikes per plant, number of seed per spike, crop yield, seed yield per hectare and fresh and dry weight of plant was highly significant, and this effect was significant on plant height, number of plant tiller and thousand grain weight. The effect of organic fertilizers on these properties was highest than others. The effect of organic fertilizer on seed qualitative traits such as mucilage percentage, inflation factor, inflation rate, nutrient content in seeds (nitrogen, phosphorus and potassium), and seeds protein and carbohydrate was highest than other fertilizers. High performance fluorescence, variable fluorescence, fluorescence maximum, number of Chlorophyll reading, Chlorophyll a and the least initial fluorescence was from treatment of the organic manure, and the highest Chlorophyll b was related to vermicomposting. The effect of fertilizers on chlorophyll b and total chlorophyll was very significant and the vermicomposting effect was highest than others. Iridoid glycoside in the leaves of Isabgol was measured by GC. Fertilizers had different effect on substance ingredient. The results showed that the effect of fertilizers on these active ingredients was highly significant. So the highest concentration of Arborescoside and Geniposidic acid was obtained from Biological fertilizer of phosphate-E-barvar 2, and Catalpol, Aucubin and echinacoside was obtained from Biological fertilizer of phosphate-E-barvar 3. Organic fertilizer produced the highest major side and Verbacoside. Gardoside and Melittoside were obtained at the control. Highest Mussaenosidic was acid related to Triple super phosphate. The effect of fertilizers on the capability of seed was also very significant, that the greatest root length, root dry weight and germination rate was obtained at the Biological fertilizer of phosphate-E-barvar 2, and the low electrical conductivity (the highest seed power) related to Biological fertilizer of phosphate-E-barvar 3. The effect of the organic manure on the length of stems, shoot dry weight and germination, was highest than other fertilizers.
