This experiment was performed to investigate the effect of Azolla and rice straw mixed compost in peat substitution on Dieffenbachia amoena. Factorial experiment based on a completely randomized design with two factors of nutrient solution in 2 levels (1- without solution, 2- with 130 mg N/ l, 32 mg P /l and 117 mg K/ l) and 5 levels of Azolla and rice straw mixed compost (zero, 15, 30, 45 and ...
Biofertilizers are important sources for plants' supplementing nutrition program, which have significant effect on reduction of costs and adverse effects of mineral fertilizers on the environment. This research was conducted as two different experiments. In experiment 1, effect of biofertilizer (0, 1 and 1.5 L nitroxin/ 500 m2), paclobutrazol (0, 25 and 50 mg/L) with/without pinching, and in ex...
Abstract In order to assess reduced nitrogen level impacts on butterhead lettuce (Lacttuca sativa L.) growth and yield, an experiment was done from May to August 2015 in research greenhouse of Shahrekord University. The experiment was conducted through randomized completed design with three replications and four treatments. The lettuce plants were grown in floating system using 60, 80, 100 a...
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...
Abstract In order to investigate the effects of nano silver and multi wall carbon nanotube levels on some morphological and physiological traits of faba bean the present study was done. This factorial experiment was conducted in a completely randomized design with three replications and two treatments with four concentrations (0,100,200 and 300 mgl-1). The results showed the total number o...
perenial rygrass (lolium perenne cv. “numan”)belongs to poaceae family as an important lawn in landscape design. the objective of this research was to evaluate effects of different concentrations of salicylic acid to enhance the growth and biochemical characteristics of lolium perenne l. under drought conditions. factorial experimental design was arranged in a completely randomized block design...
tuberose (polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. tests were done to examine the effects on of nano-silver (ns) (0, 15, 30 and 45 mg l-1) and sucrose (0, 4 and...

the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
stress management is considered as an important factor in nowadays landscape. therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (lolium...
