Abstract Book - 3rd International Symposium on Medicinal Plants ...

Plant height was not affected by P fertilizer significantly. There were positive and synergistic
interactions between factors like interactions between factors on essential oil yield. The results of
this study indicated that application of 25 kg N fertilizer per ha. and 50 kg P per ha. were the most
suitable treatments.
Key words: Essential oil yield, Cuminum cyminum, nitrogen fertilizer, Phosphate fertilizer.

<strong>Abstract</strong>: Japenese mint (Mentha arvensis.) oil is widely used for pharmaceuticals, agrochemicals
and flavoring industries all over the world. Apart from menthol, oil contains many
valuable terpenes and other minor constituents. The aim of the work was to test the efficacy of the
spray of selected phytohormones to increase the foliage growth and possibly ensure the oil yield of
crop, since a large portion of essential oil is extracted from foliage. The pot experiment was carried
out on Mentha arvensis at department of botany, Aligrah Muslim university, India to study the
Individual effect of foliar spray of 10 -5 M or10 -4 M of gibberellic acid (GA 3 ), 10 -6 M or 10 -5 M kinetin
(Kn), and deionized water(control test).The best results were obtained with 10 -5 M Kn for root
length, underground plant fresh weight and dry weight, leaf area, above ground dry matter, leaf
and stem dry weight, photosynthetic rate, stomatal conductance, chlorophyll content,
photosynthetic water use efficiency and yield parameters. However, plant height, leaf and branch
number were maximally affected with 10 -5 M GA 3 . Maximum percent increase for most of the
characters was recorded at 105 days after planting (DAP) and 10 -5 M Kn was found best
concentration in present study. Thus, the spray of 10 -5 M Kn may be used for greatest foliage
growth, photosynthetic potential and oil yield, and 105 DAP growth stage holds promising potential
for essential oil productivity and overall performance of the crop.
Key words: Dry matter, essential oil yield , herb yield, Phytohormones Mentha arvensis.

<strong>Abstract</strong>: Evaluation of growth, yield and active constituents of two varieties of Artichoke
(Cynara cardunculus ) and (Cynara scolymus) wild artichoke under different organic fertilization
was carried out. Three levels of compost (10, 20 and 30 m3 per feddan( 4200 m2 ) and /or 20 L /
fed. of compost tea were arranged in the field experiment during two successive seasons (2010
and 2011). Three cuts have been taken during the growing season. Artichoke (C.cardunculus )
produced maximum fresh leaves yield when fertilized with 20 m3 of compost + 20 L. of compost
tea , while the ideal dose for wild artichoke was 30 m3 of compost + 20 L. of compost tea. The
favonoids percentage in dried leaves ranged from 0.59---0.67 %. Poly-phenols percentage
recorded 1.26---1.43 %, where an adverse relation between these two major components was
observed.
Key words: Artichoke, compost tea, fertilization, leaves, Poly-phenols.
