    Determination of the Efficiency of Moringa Leaf Extract Treatments on Seedling Vigor in Marigold
    (2023) Özmen, Kübra; Uzunoğlu, Fulya; Erğan, Emine; Mavi, Kazım
    The effect of different planting depths on emergence characteristics was investigated in this study carried out using seeds of Marigold (Tagetes patula) collected from nature. In addition, the most effective dose that can be used in priming treatments was tried to be determined by examining the effects of moringa leaf extract treatments applied at different doses in terms of emergence rate, emergence time, survival seedling rate, true leaf emergence time, emergence speed index, coefficient of velocity of emergence and vigor index values. After the T test, it was determined that different planting depth treatments created statistically significant differences especially in the survival seedling rate. It has been observed that the fact that the planting is exposed causes an increase in the survival seedlings rate. In addition, following hydropriming and moringa treatments, the highest seedling emergence rate at both planting depths was achieved with hydropriming and moringa leaf extract (4 g L-1) treatment. Moreover, moringa leaf extract (8 g L-1) treatments exhibited the earliest emergence compared to other treatments. All treatment groups were statistically different compared to the control group in terms of emergence speed index, coefficient of velocity of emergence and vigor index values in both planting depths, and HP and M3 treatments were the treatment groups that gave the best results. As a result of the study, it has been determined that surface sowing can be recommended in marigold cultivation and moringa treatments improve the emergence characteristics.
