New Effect of Treatment with Yeast Extract and Salicylic Acid on Plant Growth of Trigonella Foenum-graecum l. Seedling

Abstract

This study was conducted at the Mosul University / College of Education for Girls /Department of Biology, in November on the local variety fenugreek to study the plant response to organic fertilizer (dry yeast suspension) with three concentrations: 0, 1 and 2 g/L and soaking with salicylic acid in three concentrations. They are: 0, 40 and 80 mg/l, the factorial experiment was carried out in a completely randomized design with three replications. The results of the experiment were analyzed and tested statistically by Duncan's multiple range test at a probability level of p=0.05%. The most important results obtained can be summarized as follows: - Fertilizing with organic fertilizer (dry yeast suspension) improved most of the studied characteristics, as the germination period was reduced and its speed increased, in addition to the homogeneity of germination, especially at the concentration of 2 g/L. "Soaking the seeds in salicylic acid had a clear effect of improving most of the studied traits, especially at concentrations of 40 mg/L The results of the binary interaction between the factors under study also indicate that the best values ​​were recorded for most of the studied traits when the factors overlapped with each other, especially when fertilizing at a concentration of 2 g/L with a concentration of 40 mg/L.
