Melt-free and basaltic (complex alumino-silicate) melt-bearing specimens of fine-grained polycrystalline olivine (Mg0.9Fe0.1)2SiO4, tested at igh temperature and low frequency in torsional forced oscillation and microcreep, display markedly different behavior. For the melt-bearing aterials, superimposed upon the high-temperature background is a dissipation peak whose height varies systematicall...
In years 2007-2008 field experiment with spring wheat was conducted on the parcels (14 m ) with 2m deep concrete walls, filled with six different soils. The goal of this experiment was to evaluate the influence of soil quality on yield and technological properties of spring wheat varieties. The results of the conducted experiment showed that the highest level of spring wheat yielding were obtai...
in order to study the effects of foliar application of si (5/1000 ratio), k (2/1000 ratio) and zn (2/1000 ratio) on rice (cv. tarom hashem), an on-farm experiment carried out based on randomized complete block design with three replications in 2012. some traits such as paddy yield and yield components, neck blast disease and stem borer damage were evaluated. results showed that the effect of fo...
One component of integrated weed management is use of cultivars with high competitive ability against weeds. Balance between competitiveness and productivity of rice under condition of presence or absence of weeds, is complicated the breeding of rice cultivars to increase competitiveness against weeds. Path coefficient analysis has been widely used in crop breeding to determine the nature of re...
Considering to drought stress importance as most important limiting factor in rice production in world, identification of tolerant genotypes to drought can be a valuable approach to deal with the drought stress. In the present experiment plant materials contains 53 rice genotypes including 31 aerobic and 22 lowland (landrace) rice that were grown in two conditions under drought stress and norma...
A finite element model was used to study the dielectric constant and breakdown strength of polymer composite filled with high aspect ratio fillers. The impact of composite microstructure and filler aspect ratio on the dielectric properties was investigated. The results were used to explain the experimental data for BaTiO3 fiber filled poly(dimethyl siloxane) published previously. The effect of ...
A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...
Ratooning means regrowing of rice plant after harvesting of first product which is specific physiologic characteristic of rice plant. It is an effective method for increasing of efficiency of production along with less investment and also lack of necessity for increasing of the field of rice plant. Ratooning more over, affects on the optimal usage of agricultural field. In order to achieve this...
Mazandaran province is an important area in rice cultivation but salinity is one the biggest constraint to obtain crop potential yield in some part of the coastal line of rice cultivated area in northern Iran. In order to find tolerant varieties and study the reaction of some newly released high yielding varieties to different levels of salinity of irrigation water a Factorial experiment was c...
