in order to study the effects of planting date and sugar beet cultivars on infection to curly top virus, vector population, damping off, root rot, and sugar yield, an experiment was conducted in mobarakeh region during 1999-2000 in a split plot design. the main factor was three planting dates and sub factor was six sugar beet cultivars: ic1 as a susceptible cultivar to beet curly top, t41r, 723...

This study was carried out to evaluate drought stress tolerance in Thymus kotschyanus accessions using a factorial experiment based on a Completely Randomized Design (CRD) with 5 replications during 2013-2014 in Qom, Iran. The first factor was the accession with 17 levels and the second factor was drought stress with three levels of irrigation including 80% (control), 60% and 40% Field Capacity...

a field study was conducted at abourehan research farm of tehranuniversityin 2009 to find out the effects of slow releasing nitrogen from pellet fertilizer of nitrogen and manure on grain yield and some physiological characteristics of corn (single cross 704). the factorial design of the study comprised of randomized complete block with three replications. factors this experiment involved: firs...

In order to investigate the effect of vermicompost and Nano Iron on yield and yield components of maize, a farm experiment was done in a factorial based on completely randomized blocks design with three repetitions in Damavand in 2013. The first factor was vermicompost in two levels included no applying and applying (vermicompost 1kg.m-2) and the second factor was Nano iron fertilizer with four...

tomato (solanum lycopersicum l.) is one of the most important vegetable plants in the world. it originated in western south america, and domestication is thought to have occurred in central america. in order to study the effect of polyethylene sheet as mulch on water requirement and yield of tomato, an experiment was carried out as factorial layout based on a randomized complete block design wi...

to study  the effect of powdery mildew on sugar beet yield and percentage of sugar losses sugar percent losses, ten genotypes were compared in a factorial  experiment based on  randomized complete block design with 3 replications and two factors. the first factor was spraying treatment with two levels and the second were genotypes. inoculation was carried out using the pathogens' conidial ...

management of soil fertility via biological fertilizers inoculation is one of the most important components based on sustainable agriculture. in order to investigate the effects of biological and chemical fertilizers on yield and some morphological traits of forage yield sorghum, a field experiment was conducted as factorial based on randomized complete block design with three replications at a...

We present here a novel, cost-effective method for increasing and controlling the ortho-para H2 (o-p H2) conversion yield. First, we invoke two processes derived from fundamental, surface science insights, based on the effect of molecular orientation on the hydrogen-solid surface reaction, i.e., dynamical quantum filtering and steering, and apply them to enhance the o-p H2 conversion yield. Sec...
