Abstract
Roselle has a very important role in farmers' income; besides the multiple Medicinal uses. In order to evaluate the effect density soil application and spraying zinc and iron on yield and quality of Roselle (Hibiscus sabdariffa), experiment split plots in completely randomized block design with three replications in Zabol university training was performed in Sistan Dam. Density at three levels of 2, 4 and 6 plants per square meter, Spraying of chelated iron 6% per 4 liters per thousand, a foliar spray with zinc chelate than 2 liters per thousand, use chelated iron 6% soil before sowing rate of 50 kg, 50 kg, soil application of zinc chelate 15% rate of 50 kg per hectare before sowing planting and spraying with water as sub plots were. The results showed that most quantitative characters, including plant height, stem diameter, number of branches, number of seeds per plant, boll weight and dry sepals and biological yield were affected by plant density. Sepals much fresh and dry weight of plants per square meter density, 4 and 2 respectively, But because of the increase in density of 6 plants Rossele. Sepals much dry so that the density of 6 plants per square meter than 2 density was 106% increased. Effect of soil and foliar micro-nutrients on capsules number, biological yield, grain weight, number of branches, number of seeds per capsules and plant fresh weight and dry sepals, indices, chlorophyll, anthocyanin content and protein content were significant sepals. The maximum chlorophyll index was obtained by spraying the plant with iron, which showed a 29 percent increase compared to control. Significant for biological yield density and micro-nutrients. Biological yield per hectare of spray on interaction density of 4 plants with the least density of 2 plants lack iron and zinc (control), respectively. Experimental results showed that the dried sepals yield per hectare for maximum density of 6 per square meter with a foliar application of zinc treatment may be appropriate.
