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...
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...
in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...
Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...
In order to evaluate salt tolerance in seedling stage, seeds of 11 hybrid and new varieties of cotton, compared to commercial cultivars of Golestan as control were planted in pot. Factorial experiment in a completely randomized design with three replications was conducted at the Cotton Research Institute of Iran in 2014. The first factor was salinity levels and the second factor was 12 genotype...
Salinity and waterlogging are two important abiotic stresses to plants growth and yield in the world. These two stresses can occur simultaneously and have additive effects on plants, including corn, growth. In a greenhouse experiment, the effects of NaCl salinity and waterlogging and their interactive effect on the growth characteristics of forage corn (Zea mays cv. single cross 704) were studi...
Uromyces phaseoli, the causal agent of bean rust, suppressed shoot and root growth of three bean cultivars, reducing root weight more than shoot weight. The greatest suppression of root weight was on the cultivar that appeared most susceptible by visual ratings of shoot symptoms. Meloidogyne incognita suppressed shoot and root growth of all test cultivars; root weight reductions differed among ...
abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...
Fungus-plant associations are of the most important mutually beneficial relationships in the ecosystem which positive effects on growth, physiology and ecology of different plants have been already demonstrated. Biological methods such as employing symbiotic (arbuscular mycorrhizal) fungi to roots of plants are considered as potential effective ways of reducing the stressful effects of soil con...
a greengouse experiment was conducted to evaluation of salinity stress on growth parameters of two olive cultivars during 2013-2014 at agricultural and natural resources research center of tehran. in the experiment, effects of five levels of irrigation water salinity including 0, 4, 8, 12 and 16 ds.m-1 were evaluated on ʻzardʼ and ʻmissionʼ olive cultivars under soilless culture. data showed th...
