| Abstract | ||||
| The effects of cyanobacterial extract and tea of the composted rice straw on some growth, flowering parameters and biochemical properties of Pelargonium zonale plants were investigated. As soil drench and foliar spraying, treatments were applied in pots trial during two successive seasons. Results indicated significant enhancements of the tested vegetative growth parameters i.e. plant height, number of branches, stem diameter, fresh and dry weights of the aerial parts due to all treatments, with relative superiority of the mix treatment as foliar spraying. Due to use the mix treatment, averages data of aerial parts dry matter during both seasons reached 19.64 % as foliar spraying and 19.42 % as soil drench compared with 10.30 % for control treatment. Similarly, root length, number of roots, fresh and dry weights of roots were also increased due to application of all treatments especially the mix treatment but as soil drench in both seasons compared with control plants. The use of the mix treatment, average data of root dry matter during the studied seasons reached 25.10 % as foliar spraying and 27.32 % as soil drench compared with 16.83 % for control treatment. So, vegetative growth parameters were increased by foliar spraying and root parameters were remarkably enhanced due to soil drench application. Moreover, all treatments tended to induce significantly increase in number of inflorescences/plant, number of florets/ inflorescence, inflorescence diameter, as well as inflorescence fresh weight, peduncle length and flowering duration. In addition, results indicated that, chlorophyll (a), chlorophyll (b) and total carbohydrates, percentages of nitrogen, phosphorus and potassium in the leaves were also significantly increased. So, application of combined treatment of cyanobacterial filtrate and compost tea, three weeks as drench soil and/or foliar spraying after transplanting of Pelargonium zonale plants, four times with two weeks' interval was recommended under similar experimental conditions of the presented study. | ||||
