تأثير مواعيد الزراعة و معدلات البذار في حاصل العلف الأخضر و نوعيته لمحصول الهرطمان Lathyrus sativus L.

Abstract EN

experiment was conducted during winter season of 2011 / 2012 to study the effect of three planting dates which were 15/11, 25/11, 5/12 with three seeding rates 40,60,80 Kg / h on the forage yield of chick ling pea (Lathyrus sativus L.

Var.Local) and the result showed that : Significant differences were obtained on growth and green and dry forage yield by planting dates and the first planting dates gave high average of plants height of grass pea also number of leaves per stems and the ratio of leaves to stems and the high green forage yield were 16.03 t / h and the dry forage yield were 6.37 t / h ,The result showed significant diffences by using high rate of seeding (80 Kg/h) which differed among the two seeding rates were used.

The best combination were obtained when the grass pea planted at 15/11 with seeding rate 80 Kg / h which gave high green forage yield was reached 18.55 t / h.
