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 research trial was carried out at University of California, Davis,
Agriculture and Natural Resources, Cooperative Extension–Kearney
Agricultural Center (KAC).
Part of the scientific work in the laboratory started from November 1, 2001
through
out the end of February 2002. This trial was conducted using Pistacia
vera; the female variety ‘Kerman’ and its pollinator, variety ‘Peters’;… both
are grafted on the rootstock UCB1.
The study has been done in many farms which are producing sweet
cherry in Lattakia during the season (2014-2015).
This research focuses on study timing of phonological stages of
sweet cherry in two regions (sluonfa , aen alhaeat) in Lattakia ciety
and studies the effect of some climatological conditions like
temperature and rain on this plant .
The result of this study revealed clear variation in the climatological
conditions between the two regions under study.
T his variation in climatological conditions led to variation in the
phonological stages of sweet cherry in two regions under study.
