ABSTRACT
Fenugreek [Trigonellafoenum -graecum L.] is an annual medicinal plant belongs to the legume family and has anti-diabetic, anti-fertility, anticancer, anti-microbial, anti-parasitic and hypocholesterolaemic effects. Evaluation of growth and trigonelline /mucilage content in fenugreek under application of plant growth regulators [PGR]. The experiment was conducted on randomized complete blocks design [RCBD] with 13 treatments and 3 replications. The treatments were consist of control [distilled water application], Giberrellic Acid [GA[3]] 25 and 50 ppm and Naphthalene Acetic Acid [NAA] 25 and 50 ppm [for each concentration by soaking the seeds before planting, spray after planting, and soaking seeds before planting with spray after planting]. Application of plant growth regulators significantly increased trigonelline and mucilage content of seed, shoots and pods dry weight per plant and 1000-seed weight. Application of plant growth regulators had no significant effect on the SPAD value. Mean comparisons showed that the highest shoot dry weight was related to NAA, GA[3] 50 ppm [soaking seeds before planting with spray after planting], and also the highest pods dry weight, 1000-seed weight, mucilage and trigonelline content of seeds were obtained from GA[3] 50 ppm [soaking the seeds before planting with spcay after planting]. Application of GA[3] 50 ppm as the soaking seeds before planting with spray after planting are effective to obtain maximum trigonelline and mucilage content in fenugreek
