In the present work ESR study of potassium borovanadate (K2O-B2O3-V2O5) glasses is reported at room temperature and liquid nitrogen temperature. The spectra similar to except indusial hyperfine lines are sharper more intense which might be ascribed a spin-lattice relaxation effect. parameters were calculated shows that in-plane π bonding somewhat covalent covalency nearly independent concentrat...

This study evaluated the influence of combinations nitrogen and potassium doses on physiology fruit production West Indian cherry irrigated with waters different salinities in second year cultivation. The experiment was conducted municipality Pombal-PB, Brazil, plastic containers adapted as lysimeters installed field, a randomized block design, 5 x 4 factorial scheme corresponding to five level...

Physico-chemical characteristics and industrial potentials of lepidolites from Ijero-Aramoko pegmatite fields were investigated . Systematic mapping indicates that the lepidolite is associated with steeply inclined pegmatite intruded into the basement rocks of gneisses and schistose assemblages that are in places pulsed with isolated Pan-African granite. The lepidolite has a layered structure, ...

The 41K/39K isotope ratio profiles in diffusion couple experiments have been measured by Secondary Ion Mass Spectrometry (SIMS). One goal of this research is to push the use SIMS measuring non-traditional stable ratios. second, more important goal, quantify for first time diffusive fractionation K isotopes and its dependence on temperature different counter-diffusion elements. data show that pr...

Global food production needs to be increased by 60-110% between 2005 and 2050 to meet growing food and feed demand. Intensification and/or expansion of agriculture are the two main options available to meet the growing crop demands. Land conversion to expand cultivated land increases GHG emissions and impacts biodiversity and ecosystem services. Closing yield gaps to attain potential yields may...

Two glass ceramics in the CaO--P2O5--MgO system with the incorporation of K2O or TiO2 oxides were prepared with the goal of using them as potential bone graft substitutes. The incorporation of TiO2 and K2O led to the preparation of specific crystalline phases in the structure of the glass ceramics, which show different degrees of biodegradation. In fact, the 45CaO--45P2O5--5MgO--5K2O has been p...

A field experiment was conducted during rabi 2021-22 at Agronomy Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat on loamy sand soil to study the response of coriander (Coriandrum sativum L.) potassium and sulphur. The laid out in factorial randomized block design (FRBD) consisted three level each (0, 20 40 kg/ha) sulphur 15 30 replicated four ...
