The aim of this study was to determine the effect of mixed multi-component fertilizers on spring wheat yield, the content and uptake of macronutrients. A three-year field experiment (2005–2007) was carried out in a randomized block design at the Research and Experimental Station in Tomaszkowo, at the University of Warmia and Mazury in Olsztyn. The experiment comprised three fertilization treatments...
The aim of our research was to determine the potential of waste generated during the production of chlorine for the synthesis of polyvinyl chloride as plant fertilizer in agriculture. For the production of fertilizer sludge produced when cleaning the saline solution, 78 vol % waste sulphuric acid from the dehydration of chlorine and calcinated magnesite were used. The product contains minimum: MgO...
A three-year-lasting field experiment involved investigation on the effect of nitrogen and boron fertilization: 80, 120, 160 kg N∙ha-1; 80 N + 2 kg B, 120 N + B, 160 N + B kg∙ha-1 on fat and protein yield, as well as energy value of spring rape seeds. The experiment was conducted on brown and grey-brown podsolic soil of slight acidity. The experiment followed a „split-plot” method, with two variables...
In a field experiment carried out in 2003/04 and 2004/05 growing season in the Agricultural Experimental Station Grabów on the Vistula river, Mazovia Province, the influence of foliar nutrition of winter wheat and oilseed rape with mixed micronutrient fertilizers (Plonvit Z/R) on the volume and quality of grain yield of wheat and rape seed was studied. The fertilizers were used alongside balanced...
The trifactor experiment was conducted at the Gorzyń Research and Didactic Institute in the years 2002-2004. Its aim was to investigate the influence of foliar fertilization with microelements and seed inoculation on the crop yield and quality of seeds of the leguminous plants. The yield of seeds and the weight of 1000 of them as well as their sowing value and chemical composition depended on the...
This study examined the sensitivity of different wheat cultivars to Cu deficiency. Winter wheat is considered as one of the most sensitive crops to the Cu shortage in the soil. Copper fertilization of wheat seams to be a necessity in our country, because of common Cu deficiency in the Polish soils. The response of ten wheat cultivars to foliar copper application was investigated in this research....
The effect of various forms of nitrogen fertilizer and dates of application on Ocimum amercianum yield and essential oil (ton/feddan, 1 feddan = 4200 m2) was studied in two successive seasons. In both seasons the total yields of fresh and dry herb after the application of ammonium sulfate surpassed that of ammonium nitrate and urea. Dividing the full amount of fertilizer into two equal portions gave...
