The experiment carried out in the agricultural Center (Boqa) of Tishreen University,
in the province of Lattakia, during the agricultural season (2014), in order to study the
effect of different types (cattle, sheep, poultry) and rates (0, 15.30 to
n/ha) of the compost
on durum wheat (Doma1). It farmed on (11.23.2014), according to complete system of
randomized sectors (27 bis).The compost was added within the lines of Agriculture
(10/06/2014). The results showed a response to the average of all the studied traits (plant
density (plant/m2), plant height (cm), the length of awn (cm), grains/spike weight (g), the
weight of 1000 grains (g)) positively organic fertilizing. While no significant differences
were recorded in the averages of the traits studied (plant density (plant/m2), plant height
(cm), the length of awn (cm), grains/spike weight (g), 1000 grains weight (g)) under the
manure type. In the case of overlap between the type and the rate of organic manure, it has
recorded a significant and high differences between the treatments. The treatment (30
ton/ha-1 poultry) was the most influential of all the studied traits. It gave the following
results: plant density (331.70 plants/m2), plant height (95.85cm), the length of awn (16.24
cm), grains/spike weight (1.66 g), 1000 grains weight (49.57 g).
This work was carried out in Al-Hwaize,Jaleh,Lattakia , in order to study the influence of seeding distances,the organic and metal fertilization on the production of safflower of dry petals and seeds and studying its morphological and variety qualities.
This research is done in an experiment by plaster in the
circumstances of Homs. The aim of this paper to study the effect of
adding four different levels of phosphogypsum as much as (0.00,
6.72, 13.44, 20.16)ton / hectare (three replicates for eac
h treatment)
on bulk density and structure stability for clay soil has taken from
(Kattina).
The results showed improvement in the stability of the structure of
soil specially (0.25-1)mm, increasing in aggregation degree ,
increasing of the rate of total porosity ,air filled porosity in
comparison to the control at the two levels(13.44, 20.16)ton/hectare
and also by increasing the added level . Whereas the dispersion
ratio , and Bulk density were decreased when increasing the level
of phosphogypsum at the same two levels.
The main achieved results in this study showed , a significant
increase in aggregation degree in the soil when increasing the ratio
of the added phosphogypsum at the levels( 6.72, 13.44, 20.16) in
comparasion with control .
In other way the dispersion ratio was decreased and had negative
relationship when increasing the level of the added
phosphogypsum in comparasion with control .
A field experiment was carried out in Hout research station- Agriculture research center in
Swaida – General Commission For Scientific Research Agricultural during the growing
season of 2015-2016 to study the effect of different levels of deficit i
rrigation with
different levels of town refuse compost (TRC)on some morphological parameters and the
productivity of lettuce and compare it with the common mineral fertilizers.
The experiment was designed as a split block design with three levels of irrigation, each
level has four fertilizing treatments and control with three replicates.
The research has studied the plant height (H), the number of its leaves (N) ,the leaf area
(LAL), the plant's leaves area (LAP), the leaves area index (LAI), in addition to the lettuce
head's fresh weight and the total productivity of the planted area.
The irrigation and fertilizing interaction results indicate to the obvious positive effect of
the organic additions on the productivity parameters and the efficiency of deficit irrigation,
and the significant superiority of T11 treatment in all of the measured parameters in
compare with the other treatments with an increased final yield of %169 comparing with
T15 and % 428 comparing with T35.
The results also indicate to the possibility of saving %25 of the consumed amount of
irrigation water by using TRC instead of mineral fertilizer , and reveal that the organicmineral
combination achieved a better yield with percentages of ( 29- 44 – 53 )%
comparing with single mineral fertilizer in the three studied irrigation levels (T1-T2-T3)
respectively.
These results give the farmer a wide range of possibilities to choose what suits his
available productivity needs , and a clear idea about the expected yield according to the
chosen treatment.
