In order to investigate the effect of humic acid (HA) and nano-calcium chelate on the cut flowers of gerbera cv. Dune, an experiment was performed as a completely randomized design with two factors and three replications in hydroponic conditions. The first factor included humic acid at 4 concentrations of 0 (control), 500, 1000, and 2000 mg L-1 as drench and the second factor was ass...

The use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. One of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. This research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

an experiment was conducted to determine the effect of paclobutrazol (pbz) and different irrigation amount on growth of aerial parts, leaf minerals and root performance in young olive plants cv. ‘manzanillo’ in the department of horticulture, faculty of agriculture, tarbiat modarres university in 2000. a split plot experiment in time was used based on a completely randomized block design with f...

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

wheat crop, considering its high planting area and consumption at national scale, demand a regular yield increase. humic acid, as an organic acid obtained from humus and organic sources without any environmental destructive effects, improves wheat yield particularly in variable environment conditions. in order to evaluate the effects of different levels of humic acid on shoot and wheat yield, a...

a new species from iran is described and illustrated here as kickxia iranica (plantaginaceae). kickxia iranica is morphologically similar to k. commutata, a species native to mediterranean region, however it can be distinguished from the latter by leaf shape, color of corolla, habit, stem branching and length of leaf, petiole, pedicel and corolla. notes on its distribution, ecology and phenolog...
