The compostion of the oils from flower and leaf of Achillea mellifolium L. subsp. mellifolium were collected during the flowering priod from Lar area to Damavand montain, altitude 3400 m in July 2003. The essential oils obtained by different methods of distillation (steam distillation and hydro-distillation), the percentage of oils for flower and leaf by steam distillation were 0.2 and 0.05% an...

a research trial was conducted during 2011-2012 to elucidate the effects of humic acid (ha) and npk to determine the optimum rate against different growth and floral attributes on tulip cultivar viz. ‘triumph’. the following five treatments t0 : (control), t1: 10 g/m2 npk (17:17:17), t2 : ha 0.75 ml (8%) + 10 g/m2 npk (17:17:17), t3: ha 1.00 ml (8%) + 10 g/m2 npk (17:17:17) and t4: ha 1.25 ml (...

Pollination is a key ecosystem service, and appropriate management, particularly in agricultural systems, is essential to maintain a diversity of pollinator guilds. However, management recommendations frequently focus on maintaining plant communities, with the assumption that associated invertebrate populations will be sustained. We tested whether plant community, flower resources, and soil moi...

to study the effect of different concentrations of potassium in thenutrient solution and water stress on the quality and quantity yield of lilium la cv.termoli, a pot experiment was conducted based on completely randomized design in sand and perlite medium (50:50) in three levels of potassium (kfree, 6 mm k and and 12 mm k in hoagland solution) with three replications. in the present study, the...

a field experiment was conducted under controlled conditions in completely randomized factorial design with three soil application doses of zn sulphate and drought stress with three replications in chalus, mazandaran province, iran on 1th march, 2015. the treatments were included three amounts of zinc sulphate (0, 30 and 60 kg.ha-1) and three amounts of stress (90, 70 and 50% of field capacity)...

To investigate the effect of irrigation and urea levels on some agronomic traits essential oil content pot marigold, a study was conducted in split-plot based completely randomized block design with three replications. The treatments included four (irrigation after 5, 10, 15, 20 days) nitrogen (0, 80, 160, 240 kg ha-1 urea). plant height, flower number, dry weight, number seeds/head, thousand k...
