This research studies the effect of mixing some locally available and cheap materials such as river sand, berlite, saw dust and lime powder with peat-moss as an alternative to pure peat-moss in making the casing layer of mushroom basins. Research in
cludes 14 treatments.
The results show that saw dust and berlite at levels of 10, 20 and 30% with peat-moss contribute in increasing the capacity of the water retention of the casing soil, compared with other treatments, having thus a positive role in increasing the production of the agricultural mushroom significantly in the first week. Saw dust treatment at 20% level recorded (16.33 kg/m2) in the same week, which is the highest production rate in comparison with the control treatment (9.5 kg/m2). Also, the total production of the first and second weeks recorded (26 kg/m2) for the 20% saw dust treatment compared to
(21.5 kg/m2) for the control.
A significant increase has been recorded in the amount of total production in all saw dust treatments, and decline in the rest of the treatments in comparison with the control. The lowest production of mushroom was (8.17 kg/m2) with lime powder treatment at 30% level. The treatments of saw dust levels of 10, 20 and 30% and berlite 20% registered an increase in the net profit and the earning potentials compared to the cost of production.
The research was performed in AL-Gab region, Hama Province during the agricultural
season 2012-2013. The investigation was carried out to assess five varieties of muskmelon
from central Asia "Gezel Zametsha, Ak Gorbek, Pakeraman, Kara Kaon, Ak Kash
", plus
control (Ananas Hollar)
The results showed that two varieties "Ak Kash and Kara Kaon " had better leaf area,
while the variety of "Ak Gorbek" had more number of feminine blossoms on the plant and
higher percentage of node blooms. "Kara Kaon" Which gave high productivity 6850 Kg/Dunm
in comparison with the control 4724 Kg/Dunm to "Ananas Hollar".
A strong Correlation link had been found out between the area of leaf surface and
productivity. The number of feminine blossoms and the percentage of the node productive
blooms. But a strong negative link was found between the number of picked fruit and average
weight of the fruit.
The goal of every industrial company is to develop and manufacture products that
suit the needs of the final customer, enabling it to market those products at a reasonable
and rewarding price. This research aims to show the importance of the adopti
on of the
quality factor in the acquisition of production requirements for equipment and machinery,
equipment and raw materials, and the statement of its significant role in reducing the cost
of production, and to make the company in a better position and ensure its survival and
continuity in the business world. The importance of this research also stems from the field
study carried out by the researcher on public industrial companies and identify the ways
and methods of purchasing, the conduct of their production, and the extent of the costs
borne by these companies to acquire better production requirements of machinery and
equipment and raw materials, and to address the main problems encountered. The most
important results obtained show that:
1.There is a crucial impact of the quality of production requirements on the cost of
production.
2. There is a crucial impact on quality cost and the improvement of financial returns.
this study was carried out during summer 2014 in Siano Research Station- the
Agricultura Research Center in Lattakia . Four varieties of Cowpea: Dolicho (entrance),
Blackey (entrance), Almaarefa (Local) and local
cultivar were planted and compared
concerning the vegetative growth , productivity
and quality of green pods.
The results showed the superiority of Almaarefa cultivar in some vegetative traits
:plant hieght (166.66) cm compared with local cultivar 116.58 cm ,number of leaves on
plant and( 27) leaves and( 17) leaves for local cultivar, and plant leaves area( 7840.23)
cm2 for Almaarefa comparing with( 4499.75) cm2 for local cultivar
As well as it had a maximum pod length( 16.71) cm and highest grain number of
pod( 9.44) ,while Blackey cultivar was the most superior comparing with
other cultivars in productivity( 0.6229) kg \ m 2 and pod's number/m2 ( 81.069)
Whereas Almaarefa had the lowest productivity( 0.4935) kg/m2 and lowest pod's number
( 65.89)pod/m2.
The results also showed that the local cultivar had the most vitamin C content
comparing with other cultivars by( 23.765%) and in dry matter by (15.38%) , while
there was no significant differences between protein green pods content.
This research aims to study the effect of different treatments of potato plants with a
feeding organ on the growth and yield of potato crop and on the quality of tubers. The
Romano variety of potato was used, and the commercial organic feeder "plan
t energy
1000" was applied in four treatments. The treatments were: a control and three ways for
treating the plants with the organic feeder: by roots, foliage spray, and by both in one
treatment.
The completely randomized design was adopted in this experiment. The experiment
was implemented in the nursery farm of Tishreen University in the spring planting season
of 2012.
The results showed that treating potato plants with the organic feeder led in general
to an increase in the growth, which was reflected in the increase in the fresh weight, total
leaf area and its indication, as well as in the quality and number of tubers, total production
and marketing quality. These results were clearer in the case of the joint treatment: root
feeding and foliage spray together. This treatment showed significant superiority in
increasing production and improving its quality.
The research was conducted on hybrid Squash (Nancy F1) at Tishreen University in
the growing season of spring 2013 in order to study the effect of ground covering and low
tunnels on the early production of squash. The study consisted of four experi
mental
treatments: the control (without covering) and three covering treatments (ground covering
using black mulch, ground covering with a low plastic tunnel, and a low plastic tunnel
without ground covering). The completely randomized design was used with three
replications per treatment and ten plants per replication. The results showed that the
covering with a low plastic tunnel was superior to other treatments, resulting in a clear
increase in female flowers, the ratio of female flowers to the total flowers, fruit number,
and plant production. The results also showed a strong positive correlation between the
plant production and the number of female flowers (r=0.999), the number of fruit per plant
(r=0.999), the ratio of female flowers to the total flowers (r=0.990) and the total number of
flowers (0.995). The correlation with male flowers was however negative (r=-0.954).
The aim of this study was comparing between three potato cultivars: "Afamia,
Loulou and Tadmur" which are planted in two different times (spring time and autumn
time), for the plant old age and some yield properties and some quality properties. Aft
er
ripping and harvesting, result showed superior Loulou to Afamia and Tadmur in most
parameters at the two planting times, so the productivity of Loulou was more than Afamia
by 6 ton/h in the spring and 1.6 ton/h in the autumn. For the starch and dry matter content,
Loulou tubers in the two planting times contained more amount than the other cultivars,
and more than the global average (%14 starch, %22 dry matter).
This research aimed to evaluate the growth and productivity of planted Pinus pinea
in pure stands at "DAHR AL SORANI" forest site. The site is about 50 km north east of
Tartous city, which is located in Temperate-Humid Bioclimate Zone.
Results sho
wed that the stands were not equivalent in growth indicators; this was due
to many factors affecting growth like site characteristics and trees density…etc. In spite of
the mediocre values of form factor, the volume and mean of annual increment was not
influenced.
Results revealed that the mean values of tree density was 851 trees/ha and ranged
between 350 - 1975 trees/ha, woody volume was averaged at 116.337 m3/ha and
ranged between 51.6519 - 215.3635 m3/ha; annual increment had also an average of 4.4548
m3/ha/year and ranged between 1.9866 - 7.9764 m3/ha/year.
The study showed a high straightness of pine. Pinus pinea trees had very rarely
forked boles.
This study was conducted in Abu-Jarash farm at the Faculty of Agriculture,
Damascus University during the main season 2013 to evaluate the effect of soil
solarization and organic fertilization treatments on the productivity of some
maize genotypes
(Basel 1, Basel 2, Ghouta 1, Ghouta 82 and Local White). The
experiment was laid out according to split-split plot design with three
replications. The statistical analysis results clearly indicated to the existence of
variability in the response of studied maize genotypes to soil solarization and
organic fertilization treatments. The genotype Ghouta 82 surpassed in the traits
of plant height, leaf area index, 100-kernel weight and grain yield (150.25 cm,
2.84, 28.10 g and 7.99 ton.ha-1) respectively, as compared to other studied
genotypes and was closely followed by the genotype Basel 2 which recorded the
highest number of rows per ear (13.83 row/ear). Soil solarization for 45 days
before sowing and applying organic manures at the rate of 20 ton.ha-1
encouraged the traits of plant height, leaf area index, number of rows and
grains per ear, 100-kernel weight which was reflected on grain yield. Therefore
we can grow variety Ghouta 82 or hybrid Basel 2 to get higher yield of maize.
The experiment was performed at Agricultural Research Center in Jousiyet
Al-Kharab in Al-Qsair district, Homs governorate during the 2010-2011 season
to investigate the effect of planting depth and organic acids on saffron growth
and productivity.
Four treatments including amino acids, amino Humic,
mixture of them in addition to the control were applied. Each treatment was
comprised of three planting depths (10, 15 and 20 cm). Results showed that by
increasing planting depth up to 20 cm a significant reduction had resulted in
the percentage of rooted plants and number of shoots while there were no
significant differences between the two depths 10 vs. 15 cm. The number of
leaves and their length were not affected significantly with the increasing of
planting depths. The number of flower, wet and dry weights of the stigmas
were increased significantly with the increase of planting depth from 10 to
15 cm. The application of the humic acids had significant superiority overall
the other applications in rooted plant percentage, number of shoots, number of
flowers and the dry and wet weights of the stigmas, while the application of the
mixture came in the second rank in number of flowers and the dry and wet
weights of the stigmas. However, no significant differences were occurred
between the control and application of amino acids. The highest percentage of
rooted plants was observed in applying humic acids in all depths and the
percentage of rooted plants reached 100%. The highest number of flowers,
highest stigmas wet and dry weights were observed with the interaction
between applying humic acids at 15 cm depth. The highest number of shoots
and number of leaves appeared with the interaction between 20 cm depth and
humic acids treatment, the longist leaves were appeared with the interaction
between amino acids and 15 cm depth.
