This research was conducted to study the impact of potassium and nitrogen fertilizers on trace element content maize (Zea mays L.). Higher doses fertilizer led a linear increase in cadmium, lead, nickel, zinc, manganese content, lower Fe:Zn Fe:Mn ratios. Moreover, cobalt level increased upon decreased higher potassium. The levels other elements (iron chromium) determined by dose and, particular...

To investigate whether the fertilizers N, P or K individually affect plant growth, oil content and the gender of sweet gale, two trials, pot and field trials, were carried out at Orkney College UHI in Scotland. A pot trial was established with eight soils which were collected from different sweet gale trial sites in the north of Scotland. Although neither shoot yield nor oil concentration in sh...

in order to evaluate the effects of organic fertilizer complements application (aminol forte, fosnutren and kadostim) on grain yield, milling properties and nitrogen use efficiency of two rice (oryza sativa l.) cultivars, a field experiment in factorial layout and a randomized complete block design with 10 treatments and 3 replications was conducted at rice research institute of iran in 2009. t...

in order to effects of fertilizer source and intercropping ratios on macronutrients concentration and uptake of fenugreek and black cumin, a factorial experiment was conducted as randomized complete block design with three replications at shahrekord university research farm in 2013. sole cropping of fenugreek (f) and sole cropping of black cumin (b) and three intercropping ratios (f:b 2:1, f:b ...

rose flower (rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. to study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of alandasht, astane ghods garden, mashhad, iran, during 2009-2010. the first factor was six cultivars of rose flower ...

This study aimed to analyze the ecotoxicity of nitrogen-, phosphorus-, and potassium-based compounds to organisms of two different trophic levels in order to compare the toxic effect between high-purity substances and these substances as components of fertilizers. Dilutions were made with the fertilizers' potassium chloride, potassium nitrate, superphosphate, urea, and their equivalent reagents...

Drought stress is a major environmental stress that restricts plant growth and production in the majority of agricultural fields of the world. The application of different fertilizers, especially biofertilizers and organic fertilizers, might play an important role in the production of medicinal plants in order to improve their resistance to deficit water stress. In order to evaluate the effects...
