نفذت تجربة حقلية للموسم الزراعي (2014/2015) في محطة الأبحاث التابعة لكلية الزراعة جامعة المثنى في العراق، لدراسة تأثير إضافة اللقاح الحيوي و التسميد المركب NPK في نمو و إنتاجية الذرة الصفراء (.Zea may L)، إذ تضمنت الأسمدة الحيوية أربع معاملات: معاملة الشاهد (صفر: بدون لقاح)، و معاملة اللقاح البكتيري Bacillus subtilis) )، و معاملة فطر االميكوريزا (Glomus mosseae) (1 كغ لقاح لكل 10 كغ بذور) و اللقاحين معاً، و ثلاثة مستويات من التسميد المركب NPK، الذي تضمن معاملات الرش على المجموع الورقي و هي : C1=5000 مغ/ليتر ، C2=7500مغ/ليتر إضافة إلى معاملة الرش بالماء فقط كشاهد C0. نفذت التجربة بتصميم القطاعات العشوائية الكاملة (R.C.B.D.) وفق ترتيب القطع المنشقة، و بثلاثة مكررات.
Field experiment was carried out at Research Station of the Faculty of Agriculture, Muthanna University, Iraq, during 2014/2015 season, to study the effect of adding NPK, biofertilizers Bacillus Subtilis and Glomus Mosseae on the growth and yield of maize (Zea may L.). The treatments were i.e control (zero: no vaccine), biofertilizers Bacillus subtilis treatments, Glomus mosseae, both biofertilizers (F0, F1, F2 and F3), respectively, Three levels of NPK liquid fertilizer i.e. 0, 5000, 7500 mg )C0, C1, and C2 respectively). The experiment design was RCBD with three replications arranged according to split plot.

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.
This study was carried out in the farm of the Faculty of Agriculture
University of Damascus during the growing season 2014, to study the
productivity of the maize cultivar ("Gouta 82) and the hybrids (Basel
1 and Basel 2) under the influence of tw
o plant densities 17.53
thousand plant. ha-1 (70x20cm) and 53.11 thousand plant. ha-1
(70x40cm).
This study was carried out during 2010-2011 growing seasons at the
Maize Researches Department (G.C.S.A.R.) Damascus. To estimate
heterosis for number of rows per ear, ear length, ear diameter, 100- kernel
weight, and grain yield.
This study was conducted at the farm of Faculty of Agricultural –Kharabo
as an intensive crop during 201 and 2012 growing seasons. Using the
Randomized Complete Block Design (RCBD) with two replications to study
some genetic indices for grain yiel
d and its components, of 79 families of the
Sh group of maize improved by Full-sib selection. The results indicated that
the broad sense heritability ranged from high to moderate for some yield
components (number of kernels per row, number of rows per ear, ear length,
ear diameter, the weight of whole ear, whole kernel weight and grain yield and
it was 49.6, 52.9, 46.3 79.7, 56.74, 51 and 85.2%) respectively. Additive gene
action appeared to be controlling number of kernel per row, number of rows
per ear, ear length, ear diameter،,grain yiel, the weight of whole ea, kernel
weight indicating less selection cycles are required to improve yield depending
on its components.
This study was carried out at the Scientific Agriculture Research Center, Al-Ghab,
Syria, during 2013 –2014 growing seasons to estimate heterosis, combining ability,
phenotypic correlation and path analysis for plant and ear height, ear length, ear
diameter,
number of rows per ear, number of kernels per row, 100 kernel weight and grain yield per
plant for eighteen hybrids produced by the line × tester method, the major findings were:
inbred lines, testers, hybrids and combining ability mean squares were significant for all
traits, indicating that additive and non-additive gene actions were the important in
inheritance of all traits. The ratios of σ2
GCA/σ2
SCA showed that non-additive gene action was
more important in controlling all traits except of number of kernel per row. Heterosis
percentage for all traits were significant compared with the check variety except of ear
height trait. GCA effects showed that the lines P1 and P7 were good combiners for grain
yield per plant, also, SCA effects showed that P2×P8, P5×P8, P4×P9 and P1×P7 crosses were
the best F1 combiners for grain yield per plant. Results of phenotypic correlation and path
analysis values showed that ear length, ear diameter and number of kernel per row were
positively and significantly associated with grain yield per plant, also, these traits can be
considered as selection criteria may lead to the improvement of grain yield in maize.
