تاثير موعد الزراعة و الكثافة النباتية في النمو و التبكير بالنضج و مكونات الغلة للفول العادي Vicia faba L في الساحل السوري

The research was carried out during the two seasons of 2001- 2002 &2002-2003 in Bouga farm of the Faculty of Agriculture to study the effect of planting dates, density planting, and effect of their interaction on growth, earliness and yield composition of faba bean cultivar, using two dates planting (early 15/11 & late 15/12,) and six density that, (33.3, 22.2, 16.7, 13.3, 11.1, 9.5 plant/ m2). The results showed the followings. Planting at the early dates increases germination percentage, plant light, number of the internodes on the stem, number of branches & pods / plant, number of seeds / pod, dry weight pod, weight seed pod, and yield plant comparing to the late planting The decrease of planting density from 33.3 to 9.5 plant/m2 caused a significant increase in all the mentioned characteristics (1) except of the germination percentage. Planting at the early date and decreased planting density decrease in the percentage of plant loss, length of internodes, the 1st stand inflorescence and the1st pod as well as a decrease in the period from planting to flowering just in the first seasons. The interaction between date planting and density planting caused positive effect on studied characteristics, and the density 9.5 plant / m2 gave higher productivity / ha. at the early date during both seasons. Therefor, it is recommended that faba bean be planted at the early date and density 16.7 plant / m2.
