Plant ambiance studies the environmental condition favorable to plant growth at initial stage of seedlings or complete production cycle. This study aimed evaluate cultivation ornamental pepper ‘Pyramid’ under protected environments and growing benches with without reflective material. The consisted a greenhouse covered low-density polyethylene film 42/50% shading thermo-reflective screen film, ...

in order to evaluate the effects of organic, biological and chemical fertilizers on yield and yield components of milk thistle (silybum marianum l.), an experiment was conducted at the research station of ferdowsi university of mashhad based on complete randomized block design with three replications and six treatments during year 2007. treatments included inoculated seeds with azotobacter, com...

A study was carried out to assess the genetic variability and association among yield attributing traits in 60 different safflower genotypes over six environments. The pooled analysis of variance (ANOVA) revealed that all attributes had a considerable degree variation.The parameters phenotypic coefficients variation (PCV) higher than genotypic (GCV)for characteristics evaluated, indicating expe...

The gas-steam power plant combines a gas and steam plant, where Heat Recovery Steam Generator (HRSG) is unit for generating steam. waste heat from this system channelled to the chimney with Thermoelectric (TEG) module generate electrical energy. TEG uses thermal conduction process wall, height, diameter, velocity variables are considered analysis. To optimize analysis, we used dimensional analy...

the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...

this study was conducted to determine the effect of cliniptilolite natural zeolite on deficit irrigation stress tolerance on maize cultivar ksc704. the experiment was laid out as a factorial design based on randomized complete block with three replications at seed and plant improvement institute, karaj in 2012. four irrigation levels, including irrigation after 70, 95, 120 and 145 mm cumulative...

to study the effect of seed density and plant distance on yield and growth parameters of radish, an experiment was conducted in research of station rice at office rasht in 2008-2009. this study was set in secondary culture after rice by factorial experiment with randomized complete block design with 3 replications. treatments consisted of factorial arrangement of three seed density levels (5, 1...

A Split plot experiment based on randomized complete block design (RCBD) with three replications was conducted in 2012,Treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (Sardari, Rijav, Biseton and Rashid) as the second factor. Plant characteristics such as plant height, length o...

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...

The introduced tree, Sapium sebiferum, is a serious invader throughout the southeastern United States. Low herbivore loads, commonly attributed to high herbivore resistance, are assumed to give Sapium a competitive advantage over native vegetation. Because herbivory resistance is considered energetically expensive, we predicted that if Sapium experienced higher levels of damage its growth would...
