Abstract:
The study was conducted in a greenhouse in lattakia at Tishreen University in 2022. Tomato seedlings (Bastona Hybred) were planted in plastic columns (50 cm height, 25 cm diameter) at a rate of one plant per column. Organic fertilizer applied at a rate of 8% of soil weight in organic treatments. Treatments were: compost of poultry manure (OM). poultry manure composted with zeolite (OMZ). poultry manure composted with fertilizer salts (magnesium sulphate: MgSO4) and (triple superphosphate: TSP) salts added at a rate of 10% of the initial nitrogen moles in manure (OMS), poultry manure composted with zeolite and salts together (OMZS), poultry manure compost and zeolite added after composted (OM + Z), and finally the Control treatment, which didn’t receive any organic source . Fruit production and plant dry weight in organic fertilization treatments of all types were better than mineral fertilization treatments alone. Composting of zeolite with poultry manure (OMZ) increased plant productivity by 21% , but did not increase dry weight. Adding zeolite after composting (OM+Z) led to an increase in plant weight by 18%, compared to the manure composted without amendment (OM). The application of salts to poultry manure (OMS) did not show a significant increase in the fruits production of OM treatment, while the dry weight of the plant increased by about 35%, and consequently, the uptake of N and P increased by 27% and 58%, respectively. The combination of salts and zeolite (OMZS) resulted in an increase of fruit production by 11%, increase dry weight by 22.5%, N and P uptake by 49% and 45% compared to compost treatment (OM). Adding mineral fertilizers to poultry manure (OMS) increased of titratable acidity and total dissolved solids (TSS) by 27% and 33%, respectively, compared to the compost treatment (OM).
Key Word: Zeolite, Magnesium And Phosphorus, Poultry manure, tomato plant.
