In field's experiment had been done in the Tartus governorate during the growing season (2013-2012) Different rates of organic fertilizers were used, the experimental transactions were (10) treatments, control (without fertilization) sheep wastes(10-
20-30)tn/h, cow wastes(10-20-30)tn/h, poultry wastes(10-20-30)tn/h.
This study aimed to know the effect of adding these fertilizers on
biological properties of the soil (the number of physiological groups of microorganisms, and soil respiration).
The Results showed increasing in the number of Hertotrophic
bacteria , Actenomycetes in the soils which were fertilized in
poultry wastes(20),(30)tn/h, and increasing in the number
of(bacteria, using mineral from nitrogen, and decomposed of
celluose micro organisms) in the soils which were fertilized in
poultry wastes(30)tn/h and cow wastes(30)tn/h.
As for fertilization, The Results showed decreasing pH in the soils
which were fertilized cow wastes(30)tn/h, while soil contents of
available P and K and organic mater increased in soil which were
treated fertilized in poultry wastes(20),(30)tn/ h, and cow
wastes(30)tn/h.
This research was conducted in Lattakia province during the year 2012 first, to
identify the current status of the production residues and agro-processing materials in the
province and, second, to introduce modern methods of taking advantage of the
m and
raising their nutritional value.
Results showed that, the most agricultural residues are not optimally used, instead,
they were disposed and accumulated causing substantial losses and environmental
pollution.
Results showed that, the investment average ratio of legume, vegetables, cereals, and
fruit trees were 75%, 65%, 60% and 40% consensually
This research conclusion shows that, the optimal use of barley residue is a source of
cheap protein units that are necessary for animals feeds; where the cost per unit of digested
protein resulting from urea treated hays amounts to 0.5 S.Y.P. This amount represents one
fifth of the cost of protein unit from barley.
Also, the use of wheat straw in the cultivation of oyster mushrooms achieve
significant economic results, the net profit resulting from the cultivation area of 10 m2 of
oyster mushrooms using 30 kg of wheat straw was about 81000 S.P.
In addition to that, the research results show the importance of agricultural waste in
biogas production and the resulting compost, which in turn has achieved excellent results
when fertilizing crops with it. The increase in the yield of maize, wheat, faba bean and
vegetables were 35.7%, 12.5%. 6.6% and 14.1-20.6% consensually.
An experiment was conducted in agricultural college arboretum that belong to
tishreen university on okra during the growing season of 2013-2014 to investigate the
effect of spraying by organic fertilizers and growing point pinching on the growth an
d
yield.
The experiment include 8 treatments as control (without spraying by organic
fertilizers or growing point pinching), two kinds of organic fertilizers (ultra humic acid and
amino vega) with or without growing point pinching. Plots were completely randomized
over the experimental area having four replicates for each treatment. Each replicate
contained 14 plants.
Results showed that the highest values of vegetative growth parameters are stem
length branch number ,leave number per plant due to the interaction between pinching of
growing point and spraying by ultra humic acid and amino vega . The experiment results
revealed also ,that the highest yield and The largest number and weight of fruits was
produced from growing point pinching and spraying by ultra humic acid and amino vega,
compared to all other treatments.
The research was carried out during 2011-2012 in order to study the effects of five
levels of fertilization (mineral fertilization N:65 P:65 K:70kg/h, and organic fertilization 5,
10 and 15ton/h), three spaces between rows (50, 75, and 100cm), one
15cm space between
one plant and another, and the interaction between them on the production of safflower dry
colored leavel, seed, and oil.
The study showed the following results: all the levels of the studied fertilization were
significantly superior in the production of dry colored leavel, seed and oil over the control.
However, there were no positive differences in the proportion of oil between the treatments
of fertilization and the control.
The 100cm farming space among rows led to a significant positive effect in the
production of safflower seeds, while the 50cm distance among farming rows in the
production of dry coloring leaves was superior over 100cm and 75cm distance. There were
no positive differences in the proportion of oil; while the mean of oil productivity came
down whenever the plant spacing increased from 50 to 75 and then 100cm.
The interaction between the levels of the studied fertilization and agricultural plant
spaces gave a positive significant effect in most studied characteristics. The most
significant positive effect was for the interaction between the mineral fertilization and
100cm distance, and then came the average of the organic fertilization 15ton/h and 100cm
space between rows.
The aim of this study was to test the effeciency of some organic and bio fertilizers in
improving the seeds germination and transplants growth of pepper Capsicum annum L.
local variaty" Qorn Algazal":by using two commercial compounds; organic (Hube
st) and
one bio (EMI) fertilizers. Two experiments were used; the aim of the first was to study the
effect of these fertilizers on germination of seeds in Petri dishes and plastic peatmoss peds.
Whereas the aim of the second experiment was to evaluate the effect of the fertilizers on
the pepper transplants growth that prepared in the 5 * 5 Striopor peatmoss plates placed in
un warmed plastic tunnel.
The results showed that the soaking of pepper seeds in the tested fertilizers, provoked
and the germination increased the seeds, vigor, with a significant performance of the bio
fertilizer.
The results also showed that the treated transplants with the tested fertilizers gave an
increase of the transplants growth ratio (the height, leaves number and foliar surface area,
the dry and wet weight) with a significance superiority of the bio fertilizer.
