The aim of this research is to determine the role of mineral (NPK) and organic fertilization (Chicken manure, Cow manure and Chicken with Cow manure) on vegetative growth and flowering of Zinnia (Zinnia elegans). This research also examines the possi
bility of relying on this organic manure to present nutrients for the plant in order to reduce mineral fertilization.
The results show that the use of NPK (30, 20, 20 g/m2) or Chicken manure (2Kg/m2) has a positive impact on vegetative growth (plant height and average number of branches andleaves on the plant). They also show a positive effect on the flower developmentand flowering (early flowering, number of flowers and flower volume). These positive effects are reflected on the proportion of dry matter both in the vegetative and flowering part. The results indicate that plants fertilized with NPK or Chicken manure realize higher economic profit than the control and those fertilized with Cow manure.
The present investigation was carried out at the nursery of Agricultural faculty- Tishreen
University, during 2016-2017, to evaluate the best organic culture medium for the seedling
production of Zinnia (Zinnia elegans) and Stock (Matthiolaincana)
with the lowest costs.
Seven different mediums were experimented (Turf, waste mushroom compost, farm waste
compost and their combinations).
The results showed some differences in chemical and physical characters of experimented
mediums. This differences had an impact on germination parameters (seed germination
percentage, speed of germination, daily germination) and seedling quality (seedling length,
collar diameter, fresh and dray weight, percentage of dray matter).
The results indicated the mediums consisting of turf (T1), waste mushroom compost with
turf (T6) and waste mushroom compost with farm waste compost (T7) gave the best
germination rate and the highest quality of seedling.
Data showed as well that T3 and T7 treatments realized the lowest costs and higher
economic profit than other treatments.
