to study the effect of humic acid and drought stress on some physiological characteristics of roselle (hibiscus sabdariffa) an experiment was conducted in the research field of agricultural education centre of jiroft in 2013. field experiment was carried out as split plot design with three replications. water deficit stress as main factor with three levels (a1 = irrigation after 50, a2 = 100 an...
Plants are faced with various environmental stresses during their growing period. Each of these stresses have different effects on growth, metabolism and yield according to the sensitivity level and stage of the plant growth. One way of reducing the negative effects of the stresses is to use humic substances. The present study was carried out to evaluate the effects of humic acid and drought st...
in order to investigate the effect of different irrigation regimes on yield and leaf proline content of a spring isfahan local variety of safflower, a field experiment was conducted as split plot in randomized complete block design with three replications at the research station of shahrekord university in 2013-2014. the main factor consisted of four different irrigation regimes (irrigation aft...
This experiment was conducted to investigate the positive effects of foliar and soil application of humic acid on chlorophyll content, flower longevity, antioxidant enzymes activity, proline, malondialdehyde and protein content in a completely randomized design with two factors: humic acid at 4 concentrations (0, 500, 1000 and 2000 ppm) and 2 application method of humic acid (foliar spray and d...
In order to investigate the effect of different levels of water deficit and foliar application of humic acid on the physiological characteristics of lima bean, a field experiment was arranged as split-split plot based on randomized complete block design with three replications in the research station of Shahrekord University in 2014. The main plot included four levels of drought stress (50, 70,...
In order to investigate the effect of salicylic acid and humic acid to mitigate the impact of drought tension during pollination of forage maize, the present experiment was conducted as split plots based on randomized complete blocks design with three replications at Isfahan University of Technology. Drought tension levels included: without tension (control), mild tension (75 percent crop capa...
Lily (Lilium longiflorum L.) is one of the most important potted flowers, which is used largely as cut flower. An experiment, arranged as a factorial besed on completely randomized dasign with three replications, was carried out to evaluate the effects of pre-harvest foliar application of humic acid, salicylic acid and calcium chloride on quality and longevity of lilium cut flowers. Treatments ...
In order to study the effects of humic acid foliar spraying on morphological traits, photosynthetic pigmentation, and essential oil content of Dracocephalum moldavica, a factorial experiment was conducted based on a randomized complete block design with three replications in Saveh. The investigated factors included the use of humic acid at four levels 0 (control), 200, 400, and 800 mg/L and eth...
abstractin order to evaluate the effect of vermicompost and humic acid on quantitative and qualitative traits of sod turf, a factorial experiment based on completely randomized design with three replications was established in research farm in shahrekord university. treatments were vermicompost (zero, 5, 10 and 15 v/v percent) and humic acid (zero, 150 and 250 g/m2), respectively. some traits s...
