this experiment was conducted to study the effects of single and combined application of organic, biological and chemical fertilizers on qualitative and quantitative characteristics of vegetative part of coriander, (coriandrum sativum l.). the experiment was carried out as split plot in time based on complete randomized block design with three replications and 12 treatments at research station,...
in order to prevent the shrinkage of olive fruit and maintain its fresh being, and also to increase the oil content and dry matter, the effect of kaolin at three levels of application (0, 2.5% and 5%) on four varieties of olive (mission, conservolea, keillet, blady) was evaluated within a period of four months, in ahwaz, the tests being repated in 3 replicates. results revealed significant eff...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
the aim of this study was to evaluate the effect of different potassium (k) and nitrogen (n) concentrations in nutrient solution and their interaction on growth and quality of tomato transplants. a full factorial experimental design was carried out with three potassium concentrations (1.5, 3 and 6 meql-1) and three nitrogen concentrations (1.5, 3 and 6 meql-1) for 27 days after seed germination...
Plant growth and development was affected greatly through salinity. Appropriate nutrients application on salinity condition can reduce its harmful effects and increased productivity of salinized soils. A pot experiment was carried out in 2007 in cs Lab., Department of Agronomy, Kyungpook National University, Korea to assess the effects of potassium nitrate on Gycine max (Var. Daewonkong) under ...
Using bacteria for producing plant nutrients, applying proper methods of soil fertility, and nutrition of plants, other than preserving environment and human health, eliminates unnecessary and wasteful use of chemical fertilizers. Thus, in order to achieve this aim, a greenhouse experiment was carried out, based on completely randomized design with three replications, in Damavand city, during 2...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
In order to study the efficacy of nicosulfuron in the control of redroot pigweed (Amaranthus retroflexus L.) using adjuvants, a greenhouse experiment was conducted at the Research Greenhouse, Faculty of Agriculture, University of Ferdowsi, Mashhad, Iran. The experiment was carried out as a factorial based on a randomized complete block design with four replications. Treatments included adjuvant...
This study examined the lodging resistance of mulberry tree (Morus bombycis Koidz. cv Kenmochi) shoots treated or not treated with succinic acid 2,2-dimethylhydrazide (SADH). The lodging safety factor, an indicator of lodging resistance, was defined as the ratio of critical lodging load to the leaf fresh weight observed, provided that the distribution of the critical lodging load along the stem...
In this study, the role of abscisic acid (ABA) in altered stomatal responses of Tradescantia virginiana leaves grown at high relative air humidity (RH) was investigated. A lower ABA concentration was found in leaves grown at high RH compared with leaves grown at moderate RH. As a result of a daily application of 20 microM ABA to leaves for 3 weeks during growth at high RH, the stomata of ABA-tr...
