أجريت الدراسة في حقل بحوث الخضر/التابع لشعبة بحوث البستنة و الغابات/ قسم البحوث الزراعية في نينوى، الرشيدية (العراق)، بهدف تقييم الأداء و الارتباط في خمسة أصناف من الفجل خلال الموسم الزراعي خريف ( 1999- 1998 ) و ( 1998 - 1997 ) أظهرت نتائج البحث وجود فروقات معنوية إحصائية بين الأصناف المدروسة و لقد تفوق الصنف الأسود (ربيع) في صفات عدد الأوراق و قطر الجذر و وزنه، إضافة إلى الحاصل الكلي (طن/دونم)، و بلغ April 11.81 و 9.22 سم و 382.91 غم و 11.67 طنًا/دونم على التوالي. في حين أعطى الصنف أعلى طول للجذر و أعلى وزن للنمو الخضري و كان 22.44 سم و 957.05 غم على التوالي. Cross كما ظهرت ارتباطات موجبة معنوية بين عدد من الصفات، و قد ارتبط الحاصل مع وزن الجذر و قطره و بعدد الأوراق / نبات و وزن النمو الخضري، أما وزن الجذر فقد ارتبط معنويًا بقطر الجذر و عدد الأوراق/ نبات .
This study was carried out at AL-Rasheedia Agricultural Research Station ,Ninevah, to evaluate five radish cultivars, during fall seasons (1997-1998) and (1998-1999) . Results showed significant differences among the different cultivars. The cultivar Black (Rabeea) was superior to other cultivars in number of leaves/ plant, root diameter, weight, and total yield /donum, which were 11.81, 9.22 (cm), 382.91 (gram), and 11.67 ton/ donum respectivelly. The April Cross cultivar gave the highest root length and foliar weight. Significant correlation was observed between cultivars. Yield was significantly correlated with root weight, number of leaves per plant and foliar weight. The root weight was positively correlated with its diameter, and number of leaves per plant.

The experiment was conducted at Tayba Research Station, General
Commission for Scientific Agricultural Research during 2011-2012, and 2012-
2013 growing seasons. Randomized block design with three replications was
used to investigate phenotypic va
riances and to determine correlation of yield
components of six local genotypes of radish. Significant differences between
genotypes were appeared in diameter, length and weight of radish root. The
correlation analysis revealed that root weight was positively and significantly
correlated with both yield (0.964) and root diameter (0.274). Yield was
positively and significantly correlated with root diameter (0.382). Root length
was positively and significantly correlated with plant height (0.333) and
number of leaves (0.329) per plant.
Five improved genotypes of durum wheat (T. turgidum var. durum) (Lahn,
Cham1, Gezira17, Bouhouth 5, and Acsad 65) were planted under the
conditions of the agricultural region (Bouka) of the Faculty of Agriculture-
Tishreen University during the ag
ricultural year 2002-2003, with a split-plot
arrangement to study the effects of flag leaf removal on grain yield and its
components.The genotypes differed significantly in flag leaf area, stomatal
frequency, yield parameters and protein content.
Flag leaf removal significantly reduced plant height, number of spikelets/
spike, number of grains/ spike, 1000 kernels weight and grain yield, while grain
protein content significantly increased.
There was a positive correlation between the flag leaf area and 1000-
kernels weight and grain yield, but protein content was negatively correlated
with grain yield.
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 investigation was conducted at the Pome and grapevine
Division in Sweida governorate in 2014-2015. Four introduced
pear cultivars (Anjou, Bartlett, Red Bartlett and Beurre Bosc) were
studied, through fruiting and growth organs, fertility, average of
fruit weight, and the yield at P< 0,05.
This study was conducted during the seasons 1995 and 1996 at Ninevah
Horticulture Station- Iraq. On Halwani and Kamali grape cultivars. This study
included four levels of foliar application of Fe-EDTA at concentrations of 0, 50,
100 and 200 ppm ir
on, and soil compound fertilization with NPK (30 kg N + 30
kg P2O5 + 30kg K2O/ Donum) on the two abore mentioned cultivars, and the
interaction among the three studied factors (cultivars, Fe and NPK), was also
evaluated.
The results showed that 200ppm of iron caused a significant increase in the
percentage of pollen viability, Pollen grains germination, length of Pollen tube,
setting of berries, ovules fertilization, leaf chlorophyll content, single leaf area,
shoot leaf area, and total leaf area per vine and leaf area per cluster. The same
results were obtained by using NPK fertilization. Halwani grape CV. Was
significantly superior over on the Kamali grape CV. in pollen viabilits, pollen
germination, length of pollen tube, leaf chlorophyll content and the single leaf
area, While the Kamali grape CV. gave the highest shoot leaf area, total leaf
area per vine and leaf area per cluster. The interaction among iron, NPK and
cultivars reveded that the best treatment was 200 ppm iron with NPK, which
gave the best results concerning flowering, setting and vegetative growth for
both the cultivars.
