In a sustainable agriculture system, application of the fertilizers which are nature friendly and suitable for plants is essential. This becomes more important when dealing with medicinal plants. Therefore, a factorial experiment in a randomized complete block design with three replications was set up in the 2012-2013 on Nigella sativa L. Treatments were nano­fertilizer (Pharmks®) (at 2 levels ...

zinc sulphate is currently used for treatment of zinc deficiency. its uptake by the body is poor, necessitating the administration of high doses. this leads to a range of unpleasant side effects. in order to increase the bioavailability of zinc, several zinc complexes have been designed and synthesized using bidentate ligands of hydroxypyranones and hydroxypyridinones. elemental analysis in eac...
