The experiment included several treatments as follows： sheep manure, 75% sheep ＋ 25% chicken, 50% sheep ＋ 50% chicken, 25% sheep ＋ 75% chicken, entire chicken manure, chemical fertilizer NPK and unfertilized control. The obtained results showed that all treatments of organic fertilization and NPK were significantly enhanced the vegetative growth parameters, sepals and concentration of anthocyanin of Roselle plants sepals. The treatment of （25% sheep ＋ 75% chicken） gave the best results： plant height （205.33 cm）, stem diameter （33.45 ram）, number of branches/plant （22.33）, total leaf area （3.29 m2）, root dry weight （56.81 g）, number of fruits/plant （110）, fresh weight of fruits （818.44 g） and dry weight of sepals （52.65 g）. But the highest concentration of anthocyanin was in the treatment of （75% sheep ＋ 25% chicken） （260.33 mg/100 g） and the lowest concentration of oxalic acid was found in the treatment of （50% sheep ＋ 50% chicken） （4.69 mg/100 g）. The results of this study showed that the use of （25% sheep ＋ 75% chicken） could enhance the vegetative growth and produce maximum yield of RoseUe calyx.展开更多

The study involved in testing the effects of two amended organic media （loam ＋ sheep manure and loam ＋ peat moss （1：1）） and different concentrations of seaweed （sea force 2） extract including （0, 0.5, 1, 1.5 and 2 mL/L） on growth and flowering of Periwinkle （Vinca rosea） plant. The results showed that growing vinca plants in peat moss medium and spraying sea force 2 extract with low concentrations especially 0.5 mL/L resulted in positive significant difference in vegetative and flowering characteristics.展开更多
