to evaluate the effect of chemical and bio-fertilizer on nitrogen, phosphorus and potash concentration, biochemical traits and calyxes yield of roselle, an experiment was conducted in the split plot based on randomized coplete block design with three replications, at the research station in zabol university, during 2013 and 2014. the main plot consisted of three levels: phosphorus, nitrogen and...
Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...
wheat (triticum aestivum l.) was grown in earthen pots containing soil of balkasar soil series (sandy loam) in green house at the department of soil science and swc, pir mehr ali shah arid agriculture university, rawalpindi during rabi season, 2007. the crop was treated with two levels of phosphorus (40 and 80 kg p ha-1 ) in the form of ssp, tsp, np and dap. a basal doze of 100 kg n and 60 kg k...
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
From this equation the value of n is easily found. In a similar manner the values of p and k are found. The value of A is then found by substitution of the known values of n, p and k in (8). Equation (4) is then available for calculating the yield to be expected from any amounts of nitrogen, phosphoric acid and potash applied as fertilizers. This matter will be presented in detail in a paper so...
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...
It is in this connection that it becomes very difficult at times for the agricultural scientist and practical agriculturist to meet on common ground, for very often a popular version of scientific reasoning may appear ambiguous, and in this case it would appear better to sacrifice the facile version (since the layman can always get an interpreter to explain if he is sufficiently interested) tha...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
Background and purpose: Fertilizer is one of the sources of heavy metal contamination in soil and underground water. The purpose of this study was to investigate the concentration of cadmium, lead and arsenic in paddy soil and underground water and its relationship with chemical fertilizer in Ghaemshahr City. Materials and methods: During the spring and summer in 2010, samples of soil were ran...
25 normal and healthy human volunteers were engaged in this investigation. The different concentration of potash alum solution have different effects on sperm, motility/death and fructose level of the semen. Higher concentration have higher effects.
