تأثير عدد النباتات في الجورة الواحدة و الرش بحامض الأسكوربك في نمو و حاصل بذور الحلبة و بعض مكوناتها trigonella foenum-graecum L.

Abstract EN

This experiment was conducted during the winter season of 2009-2010 in one of the Agricultural fields of Horticulture Department, College of Agriculture / Basrah University.

The objective of the experiment was to study the effect of plant number per hole and spraying with ascorbic acid on growth and seed yield of fenugreek (Trigonella foenum-graecum L.) and it’s components.

The experiment included six treatments combinations resulting from compatibility between plants number per hole ( two or three) and spraying with ascorbic acid (0 , 75 and 150 mg.l-1).

Randomized Complete Block Design was used with three replications.

R.L.S.D.

Test was used at probability of 5% to compare means variations.

Results can be summarized as follows: Three plants per hole gave significant increases in the height of the plant, the total number of leaves, the fresh and dry weight of the vegetative growth, the number of pods plant.-1, pods weight.

While plants non spraying gave significant increases in wet and dry weight of vegetative growth.

Plants spraying with 150 mg.l-1 ascorbic acid and non spraying plants gave significant increase in the number of branches.

plant-1 compare with that spraying with 75 mg.l-1 ascorbic acid.

While spraying with ascorbic acid have not any effect on fixed oil percentage in seeds .

The interaction of the two factors of study had significant effect on the studied parameters except number of branches.
