In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...
In order to study the effects of salinity of irrigation water on the growth and quality of 10 bermudagrass cultivars under saline soil, a factorial plot experiment using a complete randomized block design with three replications was carried out at College of Agriculture, Isfahan University of Technology in 2002-2003. Ten cultivars under five levels of irrigation water salinity (3.30, 6.93, 10.2...
Although considerable effort is being spent studying exotic plant pests, little consideration has been given as to how invasive plants might react to the increasing concentration of CO(2) in the atmosphere. Tropical spiderwort (Commelina benghalensis L.) is considered one the world's worst weeds and is becoming more of a problem in agricultural settings of the southeastern USA. Growth responses...
To evaluate the effects of row spacing and plant density on yield and yield components of sweet corn, variety KSC403, an experiment was conducted in Research Farm of Isfahan University of Technology, Isfahan, Iran, in 2007, as randomized complete block design with a split-plot layout and three replications. The main plots were allocated to two row spacing (60 and 75 cm) and the sub-plots accomm...
Salinity stress is an important challenge for wheat production in the world. Plant growth promoting rhizosphere bacteria, isolated from halophytic plants, can increase the tolerance of crop plants to salinity by direct and indirect mechanisms. In this study, plant growth-promoting traits of bacterial strains (Bacillus safensis, Bacillus pumilus and Zhihengliuella halotolerans), isolated from th...
Mutations induced by gamma irradiation are part of improving some important agronomic traits in crops. Identifying the optimal mutagenic dose is considered to be the most crucial step in trials and generating mutated genetic materials. The goal of this study was to evaluate the effect of different doses of gamma ray (0, 150, 200, 250 and 300 Gy) on some plant early stages traits and bioch...
Tomato (L.ycopersicon esculentum Mill.) cv. Rio Grande seedlings were nutritionally conditioned with solutions complete fertilizer N(60% NO3+40% NH4)-P-K (20-20-20) , N(30%NO3+70% NH4)-P-K (15-5-30) , the first two week N(60% NO3+40% NH4)-P-K (20-20-20) and later two week N(30%NO3+70% NH4)-P-K...
This study was aimed to evaluate the possibility of using enriched vermicompost with salt-tolerant strains of Streptomyces as a bio-fertilizer in growth and nutrition of cucumber under salinty stress. For this purpose, a pot experiment was set up in a completely randomized factorial design with three replications. Treatments included different salinity levels (0, 30, 60 and 90 mM sodium chlorid...
Context Rock phosphate reserves are decreasing, and requirements to mitigate environmental impacts of farming soils with excess phosphorus (P) increasing.Aims White clover is an allotetraploid hybrid between Trifolium pallescens T. occidentale. Understanding the P response characteristics these progenitor species will allow selection germplasm for development synthetic white clovers improved ph...
the present study examined the effects of mycorrhizal fungus glomus sp. on pistachio growth parameters and root-rot disease of pistachio seedlings under greenhouse conditions. the experiment was conducted in factorial arrangement based on completely randomized design with six replications. examined factors included: levels of glomus inoculation (with (m1) and without inoculation (m0) and two le...
