أجري البحث تحت الظروف البيئية لبسيرين _ حماة في الموسم الزراعي (2013-2014 م ) صممت التجربة وفق القطاعات تحت المنشقة , العامل الرئيس الأصناف ( أسكرو , راما , البلدي ) , والعامل المنشق مواعيد الزراعة ( 15 تشرين الثاني , 30 تشرين الثاني , 15 كانون الأول , 30 كانون الأول ) , والعامل تحت المنشق الكثافة الزراعية ( كثافة عالية 20 نبات في المتر المربع , كثافة منخفضة 13.33 نبات في المتر المربع ) وتبين التالي : أدى التبكير في زراعة البازلاء إلى زيادة معنوية في كل من بدء الإنبات , و في عدد الأيام اللازمة لبدء الإزهار و الإثمار , و طول فترة الإثمار . حققت الكثافة النباتية المنخفضة لنبات البازلاء زيادة معنوية في كل من طول النبات , و عدد الافرع على النبات و وزن القرن و عدد القرون على النبات , و إنتاجية النبات الواحد من القرون الخضراء , بينما تفوقت الكثافة النباتية العالية معنويا في الغنتاجية من القرون الخضراء. تفوق الصنف أسكرو معنويا على الصنفين الآخرين في كل من صفات ( عدد الأفرع , عدد القرون , إنتاجية النبات الواحد , الإنتاجية من القرون الخضراء) , بينما تفوق الصنف راما معنويا في طول النبات , ولا فروق معنوية بين الأصناف في وزن القرن . حصل تفاعل إيجابي بين العوامل المتفوقة في الصفات المدروسة .
The research was conducted during the growing season in 2013- 2014 in Bssiren Hama. In a split- plot design: the varieties were main plots (asgro, rama, Muncipal) and the sowing dates were subplots (15\11;30\11;15\12 and 30\12) and the densities were subplots (20 plant\m2, 13.33 plant\m2). The early planting went to Significant increase in the days to germination, long time of fruit; the number of days to flowering and the number of days to fruiting; Plant height; Number of branches plant ; weight of pod; number of pods plant; dressing percentage; Yield of green pods plant and Yield of green pods. While the high density was observed Significant increase in the Plant height; Number of branches plant; weight of pod; number of pods plant; and Yield of green pods plant, while the low density was observed Significant increase in the Yield of green pods. The Asgro variety was obtained at Rama and Muncipal varieties in the number of branches plant; number of pods; Yield of green pods plant and, while the Rama variety was obtained by the plant height, and non- significant results were found among varieties by the weight of pod. The positive results also showed in the interaction among factors.

We evaluated some of the qualities of productivity for lentil
variety ( Lens esculanta ) Idlib2 in the province of Hama, which
lies within the third zone in the two seasons 2013- 2014. manner
random sectors dissident once and three replications fo
r each
worker where she planting dates widget Home and operated plant
density widget dissident once in order to determine the date and
density suitable to reach the best production of lentils in a peaceful
area.
Agriculture led on the first date (December 15) and in the
plant a minimum density (200 seeds / m2) increased to varying
significantly different in the length of the century / mm and the
total number of horns on a per plant and the number of seeds per
plant and seed weight on a per g / plant and seed weight per hectare
And it gave the plant Top-density (300 seeds / m 2) a significant
increase in the weight of centuries per g / plant and the number of
pods on the plant and the weight of Aalakec per hectare and
biological weight per hectare.
Luteoviruses were recognized as a major cause of yellowing, leaf rolling and
stunting in chickpea (Cicer arietinum L.) in Syria. Aphid population dynamics
in two consecutive seasons (١٩٨٩/٩٠ and ١٩٩٠/٩١) showed a peak in April
followed by high lev
els of virus incidence and ranged between ٤ – ٧٨,٤ %.
Different sowing dates of four chickpea varieties (local chickpea, Ghab١,
Ghab٢ and Ghab٣) showed that early planting lead to disease escape, by
avoiding early infection. The yield average of the four chickpea varieties was
increased by ٢٦٠% in the first season and ١٤٠٪ in the second, when the crop
was planted early. Weeds have been studied as a potential over-wintering hosts.
A range of weed species mostly with yellows symptoms similar to those caused
by luteoviruses were collected from the field trial and tested. They proved to
host aphid vectors as well as luteoviruses.
It is well established that sugar content of sugar beet increases as the plant
reaches the biological maturity stage. This means that the sugar beet plant
must be left in the field to complete its growth. Farmers are usually concerned
with the hig
hest yield of sugar beet roots regardless of their content of sugar,
but sugar-processing companies are concerned mainly with the amount of
sugar extracted from a certain weight of roots, in addition to the purity of the
sugary juice.
Farmers normally receives the price of their sugar beat crop based on the
sugar content of the crop. Thus, in this type of farming, biological control is a
worldwide-procedure.
Biological maturity depends on ways of yield formation and a close control
of the mechanisms of forming yield components (no. of roots / unit area;
average root weigh; average sugar content) which require a detailed study of
the characters of the grown cultivar and the overall conditions of the growing
area.
Results showed that harvesting of sugar beet sown in fall season befor the
plant completes it’s growing cycle (in June) results in a big yield in addition to a
reduction in sugar content in the roots which inturn results in a big loss in the
national economy.
Results indicated that delaying date of harvest up to ١٨th of July markedly
increased root and sugar yield as well as sugar content in the beet roots.
Increasing nitrogen rate up to ٤٠٠ kg / ha resulted in a marked increase in root
and sugar yield / ha . On the other hand, sucrose content gradually decreased
with excess nitrogen. Higher plant density (more than ١٠٠,٠٠٠ plants /ha)
enforce for late harvesting in comparison with other densities for at least ١٠
days to obtain high yield of roots and sugar.
Experiments were conducted to study the effect of four chickpea plant
densities (٢٠, ٢٥،٣٣,٣ and ٥٠ plants/m٢) during ١٩٨٩, ١٩٩٠ and ١٩٩١ seasons
on podborers in southern Syria in three chichpea cultivares (Ghab l, Ghab ٢
and local).
The research was carried out in the agricultural season 2016-2017 the village of
DweirRaslan Tartous governorate with three planting dates (20 November - 10 December -
1 January) and three densities (12 - 14 - 16 plants / m2) Where the planting tim
e was the
main pieces and the plant density occupied the dissecting pieces once to study the effect of
planting date and plant density on some morphological characteristics of white thermos
plant.
The results showed that dates of the early dates (November 20) were higher in plant height,
with an average of 64 cm and surface area of the paper surface at an average of 24.367
thousand. M 2 / ha and in shape of the length of the century with an average of 7.50 cm.
As for the plant density, the plants of density12 plants / m 2 in the height of plant exceeded
an average of 65.6 cm and length of the century with an average of 8.13 cm, while the
plants of density 16 plants / m 2 in the area of paper area average 24.213 thousand. M2 / ha
