Effect of mineral fertilizers with different sulphur content on the yield of winter wheat in a small plot experiment
Published November 2, 2009

We can find more and more references on the importance of sulphur and sulphur fertilization, mainly in the case of most important field crops, as cereals, maize, and the oilseeds. The traditional sulphur sources continuously lost their importance by the stringent air pollution orders and nowadays they are not able to meet the demands of plants.... Besides, the application of superphosphate, as phosphorus mineral fertilizer, decreased in several countries. Sulphur fertilization is required in most cases to reach the required yields and quality parameters. The lack of
sulphur causes decreased nitrogen utilization and yield by cereals as winter wheat, moreover, results less favourable baking parameters.
We have examined the N and S content of different parts of winter wheat plants in a small plot experiment at the University of Debrecen, Centre of Agricultural Sciences, Látókép Experimental Station. We have also studied the effect of different sulphur fertilization forms and doses on the baking quality parameters and yield. Our aim was to contribute to the development of yield and quality improving sulphur fertilization methods, adaptable by practice.
We have measured the lowest yield in the case of one of the control plots, and 100 kg/ha nitrogen, 80 kg/ha potassium and 70 kg/ha phosphorus nutrient supply resulted the lowest yield (8.7 kg/plot). The maximum yield, 10.2 kg/plot was also experienced on superphosphate fertilized plot by the application of 140 kg/ha phosphorus dose. Application the first dose of both Biofert and FitoHorm 32 S leaf fertilizers raised the yield from
9.1 to 9.9 kg/plot. ANOVA proved that Biofert and FitoHorm 32 S had no significant effect on the amount of yield, the increase is only a tendency.

Response of sugar beet to different foliar fertilizers
Published December 21, 2008

The yield and quality of the sugar beet are mainly determined by level crop production system; therefore the effects of foliar fertilization were studied. Our field trials were carried out in 2005  and 2006 in Hajdúböszörmény, at two experimental sites. In our trials the effects of Biomit Plussz, Fitohorm and Kelcare Cu (having high Cu... content) as foliar fertilizers, as well as a fungicide with high sulphur content, Cosavet DF, were studied and
compared. Effects of treatments were studied in four replicates. 
We took root samples at 4 week intervals, starting in August. The quality of root (sucrose, potassium, sodium and alfa-amino N content) was determined from filtrated beet broth, by an automatic beet laboratory system, called VENEMA. Leaf samples were taken three times in the growing season, element composition was measured by ICP-OES.
We found that the crop and the sugar yield were significantly influenced by the foliar treatments both of the two years.

Results of a Fertilization Experiment Performed with Sulphur on Rape Seed Plants
Published May 4, 2004

The sulphur fertilizing experiment was introduced in the cropping year of 2001/2002, with winter rapeseed. The experiment was performed on a farm in Magyarhomorog, Hajdú-Bihar County. By selecting the location for the experiment, we had to consider the effect of the hard winter that was very unfavourable for rapeseed production, as there was s...erious frost damage on the sown area previously used for the experiment. In the arable land experiment, results of three different doses of treatment were compared in two replicates, on meadow soil. FitoHorm 32 S solution was used as a sulphur fertilizer, in doses of 3, 6 and 10 l/ha. Evaluating the results, we tried to find a correlation between the amount of fertilizer and the amount of seed-crop or the oil content of the seed. The nitrogen and sulphur contents of the samples were determined using classical methods and an Elementar VarioMax analyser. By this way, it was possible to examine not only the role of Sulphur in rapeseed production, but also to compare and evaluate results obtained by Kjeldahl and the modern, environmentally-friendly combustion method.

Results of Sulphur Fertilization Experiment with Oilseed Rape
Published September 8, 2020

The rape is definitely a sulphur-demanding crop, which yield and the quality of its oil is threaten by the emerging shortage of sulphur nowadays. We made sulphur fertilising trials on two places in the northeastern rape growing area (in Felsőzsolca and Mezőkövesd), in the season 2001/2002. We compared the result the 5 five treating set in 2 ...repeats on brown forest soil with the results of the control plots. We used FitoHorm 32 S sulphur solution as sulphur fertiliser, with the dose of 3, 6 and 10 litres per hectare, as well as the joint effects of sulphur and boron; and the effect of boron alone. On the assessment of our results we looked for relation between the sulphur fertilising, the seed production, the oil content and the protein content.
