The research was conducted in plastic green house for the 2013-2014, in Alqangerh
village, about 5 Km from the city of latakia, in order to study the effect of spraying the
leaves with some humic compounds and amino acids on growth and production o
f hybrids
of cucumber (Novo,Dorruk).
Spraying leaves with three organic fertilizers are (Huzone, Mol mixs), and two boats
Dbalin and Amino vega (an amino acid).
The results showed that all treatments of leaves spraying with organic fertilizer geve
better resultus with significant differences than the control treatment in all the studied traits
of both hybrids: (stem length, number of branches/plant, number of leaves/plant, leave area
cm2, the number of flowers on the stem, number of fruits on the stem, number of floral
branches, number of fruits on the branches).The treatment of spraying achieved with
mixture of humic compounds and amino acids increase with significant differences in both
the number of leaves/plant, number of branches/plant, the plant's stem length and number
of fruit on the stem in the hybrid Novo. while the treatment of spraying achieved of hiozon
increase with significant differences the number of branches/plant, the number flowers on
the branches and number of fruits on the branches was in the hybrid Dorok. As for the
early production and total production, the treatment of spraying with mixture of humic
compounds and amino acids with significant differences on other transaction when both
hybrids Novo and Dorruk amounted, respectivety (5 ، 4,1 kg/m2 ; 16 ، 14,8 kg/m2 ).
The experiment was carried out at the end of April during 2013 In Abi-
Jarash farm, Faculty of Agriculture, Damascus University in order to
determine the influence of organic fertilization on the growth and yield of Snap
bean. The snap bean ”Tema”
Phaseolus Varity, and organic fertilizer” Humax”
with two methods (root application and foliar spry) and two concentrations (2
and 4 g/L) were used. The organic fertilizer was used after two weeks of
germination and then two weeks between treatment and another and the
experiment was laid according to simple randomized block design. Results
showed that organic fertilizer caused an increase of plants growth and yield,
and the foliar spray method showed significant superiority (p<0.05) to some of
the studied parameter such as plant dry weight (6.89 g), leaf area (4595.44 cm2),
leaf area index (2.55), number of clusters (15.3 cluster/ plant), number of pods
(29.6 pod/plant), plant yield (156.9 g/plant), compared to the root applied
method. Results also showed no significant effect for the fertilizer
concentration.
This search was carried out in Abi Garash farm, Faculty of Agriculture,
Damascus University to study the efficiency of using “Agerton” as a fertiliser;
either by irrigation or a foliar spry on tomato seedling. Four varieties were
used (Astona, Tyr
ad, E26 and Local).
Results showed that the treatment by the fertilizer resulted in an increase in
growth thorough the plant length increasing. This increase was about 1.1 and
1.2 folds for all varieties and types of treatment (irrigation and foliar spry), as
compared to the control.
Moreover, the using of fertilizer led to a significant increase in the yield of
plant, which increased by 1.2 and 1.5 in Astona; 1.2 and 1.4 in E26, 2.2 and 2.3
in Local and 1.5 and 2 in Tyrade, for the treatment of irrigation and foliar spry,
respectively.
A field experiment was carried out to investigate the effects of organic
fertilizers (mushroom substrate residues, poultry manure and city compost)
and mineral fertilizers (NPK) on some properties and productivity of a
calcareous soil using chard
(Beta vulgaris) as a test crop. The plant was
cultivated at spring season 2009. The first cut was after 60 days of swing. The
results of experiment were: The NPK fertilizer significantly affected dry weight
of plant yield (157.6g/m2soil) and the efficiency of fertilizer in productivity was
50.8% compare to control (104.5g/m2soil). The treatment of 50% NPK + 50%
poultry manure gave the highest yeld compare to other treatments. However
the organic treatments did not differ significantly among them. Concentrations
of NPK nutrients in plant leaves were as follows: NPK > 50% NPK + 50%
poultry manure > poultry manure > 50% NPK + 50% mushroom substrate >
mushroom substrate > 50% NPK + 50% city compost > city compost. The
organic fertilizers decreased the NPK in plant and soil compare with NPK
fertilizer treatment. However there was no significant differences between NPK
treatment yield and 50% NPK + 50 % poultry manure treatment. It was
concluded that the use of 50% NPK +50 % orgnic fertilizer (specially poultry
manure) was important to get best result.
Effect of organic and bio fertilizers (Azotobacter and phosphate solubilizing
bacteria) on production of potatoes and some soil properties was studied in
Tartous.
The experiment consisted of 4 treatments (control soil, soil+manure, soil+
bioferti
lizer and soil+manure+biofertilizer) each replicated four time, for 2004
and 2005 seasons.
Total N, available P, available K, and organic matter in soil were
determined.
Significant increases were observed in most of the inoculated and organic
fertilized treatments compared with the control. However, the treatment
(soil+manure+biofertilizer) was the best and showed significant increases in
potato yield compared with other treatments especially in the next season.
However, the second season was better in yield increase in all treatments
than the first seacon.
The research aims to study the effect of certain organic and amino
compounds in the growth and production of tomato under green
houses conditions.Hulay F1 hybrid tomato and two organic
commercial vehicles differing in composition Hupost and
Boldo
uzerwere used.The experiment done in a way randomized
complete blocks designed , with three replicates per treatment , and
10 plants per replicate . Seedlings WERE Prepared in beet moss
using trays of Alstrepor inside the greenhouses.
This search aims to study the efficiency of using“Biotolerance” as a
fertiliser; by a foliar spry on Pepper seedling. Four varieties were
used (Marcony, California wander, Maroty-7 andRobber). The
results showed that the treatment by the fertilizer resulted in an
increase in growth thorough the plant length increasing.
The effect of clay soil treatment with two levels of tobacco west compost and
organic fertilizer (15 and 30 ton/ h), in addition to mineral fertilizer treatment, with three
replicates of each treatment on some physical properties (Aggregate size di
stribution, main
weight diameter, bulk density and porosity) and chemical properties (Organic carbon,
humic and volvic acid and humification index for big and small soil aggregates was
studied.
The results showed that tobacco west compost and organic fertilizer were effective in
increment of soil content of organic carbon, which reached (20 and 26%) for organic
fertilizer, and (39 and 45%) for compost compared to the control, conducing to ameliorate
soil physical properties, where The main weight diameter, stable aggregate rate and soil
porosity were increased. Whereas, bulk density decreased significantly in both treatments
compared to the control. Compost treatment affect soil physical properties more than
organic fertilizer.Mineral fertilizer decreased soil content of organic carbon compared to
the control.
Humic and volvic acids contents were between 2.12 and 74.3 mg/kg aggregates in
the control,and compost treatments alternatively in macro aggregates (> 2mm). Wile,
volvic acid values were between 0.93 mg/kg in control for small aggregates (< 0.25), and
3.17 mg/kg aggregates in mineral fertilizer treatment for (0.25 – 2) aggregates.
Humification index values were less than 2 in macro aggregates, while it was bigger than 2
in small aggregates.
A field experiment was conducted in the open field during the
autumn season in year 2015 to study the effect of spraying with two
organic fertilizers (Crop + Extra, Cremalga) on flowering and yield
parameters of cultivars cucumber Maximus F1.
This research was conducted in plastic house in Zahed local for organic
agriculture in Tartous in two agriculture season during(2014-2015)
and(2015-2016) to study the effect of solid and liquid organic fertilizer from
digstate in some Physical and Chimical Characteristics of Tomato fruit
(hybride Nesma) in green house.
