In order to study the effect of phosphate biofertilizer and chemical fertilizers of nitrogen, phosphorus and sulfur on some growth and yield components of Camelina sativa L., a study was conducted based on a factorial experiment; this was done in a randomized complete block design with three replications at Kazeroon during the 2016 growing season. Treatments included bio-based phosphorus (P)...
Background: The declining soil fertility is a severe bottleneck for crop production in Ethiopia. application of inorganic fertilizer helps to correct site-specific nutrient deficiency. Methods: research was conducted at Achura kebele Farmers Training Center (FTC) from December 2020 July 2021. Soil samples and data were collected analyzed by standard procedures. Result: reaction revealed that th...
to study the effects of biological and manure fertilizer on quantity and quality characteristics of roselle (hibiscus sabdariffa l.), an experiment was conducted as split plot based on a randomized complete block design with three replications at the agricultural research center of zabol university, iran during growing season of 2012-2013. treatments included three manure level; 0, 10 and 20 t....
In order to study the effects of foliar application of potassium (K) and boron (B) and dificit irrigation treatments on quantitative and qualitative traits of sugar beet (Beta vulgaris L.), a split plot experiment was conducted based on randomized complete block design with three replications in the Research Field of Shahrekord University, Shahrekord, Iran, in 2019. The main plots were allocate...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
A boron isotope study combined with analyses of elemental boron, lithium, and chlorine is used to suggest that brines from the Dead Sea and on-shore hypersaline thermal springs (Hamme Yesha, Hamme Zohar, and Hamme Mazor) are the products of interaction of evaporated seawater with detrital sediments. The high 6”B values of the Dead Sea brines (55.7 to 57.4%0 versus NBS-951) and the hot springs (...
The absorption of the H2S on the small boron nitride fullerene (B12N12) and its Al-inserted analog was theoretically analyzed by density functional theory. The structural stability was based on the minimum energy and non-complex vibrational frequencies. Different sites and orientations of H2S, using the monomer unit, were considered. Compared with the...
A field experiment was carried out at the Research Center of Barkat-e-Jovein, Jovein agro-industries, Northeastern Iran, during 2008 to evaluate the effect of concentration and time of boron foliar application on root yield and quality of sugar beet (Beta vulgaris). Treatments consisted of 3 application times (30, 45 and 60 DAP) and 4 application rates (spraying with concentrations of 0, 4, 8 a...
the role of calcite as related to the chemical behavior of boron (b) in calcareous soils was investigated through an assessment of b adsorption and desorption reactions on and from calcite in four ratios of solid to solution rate, three levels of ionic strength, and within a ph range of 7.5 to 11.5. experimental data indicated that b adsorption is increased by an increase in the solid to soluti...
