AbstractThis study was conducted on Department of Horticulture, collage of Agriculture, University of Baghdad to investigated the effect of soil and foliar fertilizer application on fenugreek seeds content of medical compounds.
The experiment was adapted using Split plot Design with three replicates for each treatment except the tow cultivars of fenugreek, Iraqi and Yemeni as plots while N, P, K, in four level for each of them as sub plots and the foliar application of Fe, Mn, Zn, B, Co as sub- sub plots. The application of P were done before planting. N and K were divided into tow groups, the first addition was at planting and the second addition was after 75 days from planting. The foliar application of the nutrients were applied after 45 days from planting and the second sprays were done after one month from the first spray.
200 gm of seeds were taken for each treatment for both seasons and extraction of these seeds were done to investigate the effect of the experimental treatments in the medical compounds of these seeds.
The experimental results shows that the treatment with third level of NPK and tow foliar spray, with nutrient significantly superior than other treatment on oil content as compared with the control, with the ratio of 40 and 37.5% for the Iraqi and Yamni cultivars respectively. Treatment the plants with the second level of PNK and the tow foliar application with the nutrients significantly gave the highest Mucilage compound and with a percentage of 50% and 60% as compared with the control for the Iraqi and Yamni cultivars respectively.
The extraction and diagnosis of fenugreek seeds using HPLC shows that treating fenugreek plants with the second level of NPK and tow foliar spray with nutrients significantly gave the highest Alkaloids content which increased by a percentage of 61% and 67% for Yamni cultivar and 67% and 65% for Iraqi cultivar on compared with the control. The same treatment significantly superior than the control in the asteroid sapponin with a percentage of 56% 50% for the Yamni and Iraqi cultivars for both season.
