يتناول هذا البحث أسس تحليل التباين و تطبيقاته حيث أنه يتعامل مع تحليل التباين الأحادي ثم الثنائي و يقوم بتطبيق الدراسة النظرية في المجال الزراعي . و لقد اخترنا محصول القمح حيث قمت بدراسة أثر موعد الزراعة و أثر الكثافة النباتية لمحصول القمح على إنتاجية هذا المحصول ثم عرضنا النتائج التي حصلنا عليها باستخدام البرنامج الإحصائي SPSS. أخيرا .. إن هذا البحث يمكن الاعتماد عليه في أبحاث أخرى تستخدم طرائق تحليل و أنظمة إحصائية أخرى في تحليل التباين .
This work deals with the analysis of variance basis .It starts from monofactor analysis of variance to bifactor analysis of variance . Then , I applied the already mentioned theoretical study to actual issue in the agriculture field . I have chosen wheat and studied the best date to plan it and the best Plant production through a detailed study based o SPSS program . then , I showed the results of each variable in a detailed . Finally , this work can be a basis of another work using other analysis methods and other statistical in the analysis of variance .

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.
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 we
re 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.
The aim of this research is to determine the best date and culture medium for the
production of big rolls consisting of seed mixture (Lolium perenne, Festuca Arundinacea,
Festuca rubra, Poa partensis) with the lowest costs. Seven different mediums
were
experimented in two different culture dates (15 September and 1 April).
The results showed that the mediums consisting of turf or spent mushrooms compost
gave the best germination rate (78-84%) in the two culture dates. They also gave ready big
rolls in a period of time less than in the other mediums (78-102 days). The mediums also
gave the best quality of big rolls in terms of light weight (41.96- 53.89 kg/m2), coverage
rate (93-98%), and color.
The medium that consisted of spent mushroom compost achieved an economic
increase higher than that in the other mediums, where the coefficient of profitability in the
former was (194.4%).
نفذ البحث خلال الموسم الزراعي (2014) م في الساحل السوري في محافظة طرطوس لدراسة تأثير أربع كثافات نباتية وثلاث مستويات من الأسمدة
The research was executed within the season 2016, in the west of
HOMS in the first settlement area.
The study has showed the effect of plant density and nitrogen
fertilization was studied on the growth and productivity of soybeans
Glycine max L . (Sb44).
