تأثير الكثافة النباتية على نمو و إنتاجية محصول القوار

Abstract EN

The effect of plant population on the guar growth and seed production.

The experiment included field trails carried out in the farm of the Collage of Animal Production , kuku town , in the growing season 2001'-2002.

the experiment investigates the effect of plant population on plant growth , productivity , protein content, ash and dry matter in the guar seeds.

Treatments included four seeding rate , 2, 3, 4.

and 5 Kg / feddan , grow in raws.

Measurements taken for study included the vegetative and reproductive growth period height plant number of branches /plant , the total number of pods / plant, number of seeds / plant, average weight of 1000 seeds and total seed production /ha.

The chemical analysis of the Guar seed has been estimated.

statistical analysis indicated that the seed rate / unit area, his significant effect on the vegetative growth period , plant height number of pods / plant, number of seeds / pod and the weight, of lOOO seeds.

The highest yield was obtained at the seed rate of 3 Kg /feddan which resulted in 1.9 Ton / hectare.

At the seed rates of 4 and 5 Kg / Fe.

the yield decreased with about 7%and 25 % respectively'.

The chemical analysis nroved that there is no significant effect for the seed rate on chemical component of the Guar seeds.
