| Abstract | ||||
| Improving the growth and productivity of flower bulbs via biostimulants is a very imperative topic. Therefore two field experiments were conducted during 2016/2017 and 2017/2018 seasons to investigate the efficacy of moringa leaf extract (MLE), seaweed and/or GA3 treatments on improving the growth, flowering and corm production of gladiolus. MLE was extracted and diluted at a ratio of 1:30 (v:v). Seaweed was applied at 1g/L. Moreover, the applied concentrations of GA3 were 0, 50, 100 and 150 mg/L. The growth characters and flowering attributes were significantly improved compared with the control due to MLE or seaweed as a solely treatment or even in combination with GA3 concentrations in both experimental seasons. The productivity of corm and cormlets was also enhanced by using both biostimulants and/or GA3 application. Furthermore, the chemical analysis indicate that N, P, K, total chlorophyll and total carbohydrate content were increased in gladiolus leaves treated with MLE or seaweed and/or GA3 treatments in both seasons. Conclusively, MLE, seaweeds and/or GA3 applications enhanced the growth characters flowering attributes and corm production of gladiolus. The most effective treatment was MLE and GA3 at 100 mg/L. MLE and seaweeds may be applied as a promise and ecofriendly plant growth stimulants to modulate the growth and productivity of gladiolus. | ||||
