KAYMAK, H. C., 2013. Effect of nitrogen forms on growth, yield and nitrate accumulation of cultivated purslane (portulaca oleracea l.). Bulg. J. Agric. Sci., 19: 444-449 The present investigation was carried out to determine not only the most appropriate nitrogen form but also the effect of these forms on growth, yield, element content and nitrate accumulation of cultivated purslane (portulaca ...

The effect of carbon nanotubes, calcium chloride and potassium nitrate on germination traits Iranian Oak seed (Quercus brantii)

The asymmetric unit of the title compound, [Ni(C(3)H(10)N(2))(2)(H(2)O)(2)](C(4)O(4))·4H(2)O, contains one-half of the diaqua-bis(1,3-propane-diamine)nickel(II) cation, one-half of the centrosymmetric squarate anion and two uncoordinated water mol-ecules. In the cation, the Ni(II) atom is located on a crystallographic inversion centre and has a slightly distorted octa-hedral coordination geomet...

minoodasht which is located 18 km. far from the east of gonbad-kaboos, is one of the most important agricultural areas of iran. a great development in the agriculture of this area has been achieved by drilling wells, building canals, constructing the dams and also irrigation of the farms by pump. for determination of the physical and chemical characteristics of the waters from different sources...

The crystal structures of the tri- and tetrahydrate of tin tetrachloride, viz. diaquatetrachlorotin(IV) monohydrate, [SnCl(4)(H(2)O)(2)].H(2)O, and diaquatetrachlorotin(IV) dihydrate, [SnCl(4)(H(2)O)(2)].2H(2)O, are reported and shown to contain the cis-[SnCl(4)(H(2)O)(2)] species and water molecules in both cases. The trihydrate contains chains of the tin species linked by a single hydrogen-bo...
