To evaluate the economic efficiency of irrigation in corn cultivated for grain, production effects were used, which were obtained from studies conducted by researcher team from the Department of Land Reclamation and Agrometeorology at the Experiment Station of the UTP University of Science and Technology in Bydgoszcz in 2005-2016. The research covered the effect of irrigation on yielding of the crop. Economic efficiency calculations were made using the direct surplus increase calculation method. In each variant irrigation enhanced production effects. It was not always economically justified, however. The irrigation costs (for drip and sprinkler irrigation systems) per hectare were decreasing with an increase in acreage. Applying drip irrigation was economically unjustified in moist years and on average in the multi-year period. In the years with dry and average precipitation conditions the direct surplus was positive, except for irrigation of 1 ha. As for the sprinkler-irrigation system, a lack of economic efficiency was reported in moist years, whereas in dry and average years as well as on average in the multi-year period, except for 1 hectare acreage, corn sprinkler-irrigation was economically justified. ...
The aim of the research was to evaluate the effect and interaction of sprinkler irrigation and nitrogen fertilisation on the grain yield and baking value of ‘Monsun' spring wheat cultivar grown in light compacted soil. A field experiment was performed in 2013-2014 in an experimental field of the Department of Land Improvement and Agrometeorology, the UTP University of Science and Technology, at Mochełek, in the vicinity of Bydgoszcz. It was found that sprinkler irrigation significantly increased the spring wheat grain yield. The grain from sprinkler-irrigated stands demonstrated greater plumpness; it contained significantly less protein and gluten and showed a lower sedimentation value, as compared with the grain of non-sprinkler-irrigated plants. However, the protein yield produced under sprinkler irrigation conditions was on average 11% higher, compared to the control conditions. The effect of nitrogen fertilisation on the spring wheat grain yield and quality correspond to earlier findings. Similarly to other research reports, a regular yield increase and enhanced quality of baking features along with an increase in the nitrogen rate were identified. Considering the quantitative and baking features of the grain yield, it was found that the optimal nitrogen fertilisation rate in ‘Monsun' spring wheat, in both water variants, was ...
The aim of the research was the evaluation of sprinkler irrigation and nitrogen fertilization on some selected features of the quality of malt and wort from ‘Marthe' and ‘Mauritia' malting barley grains. The field experiment was carried out in the years 2010-2012 at the Research Station of the University of Science and Technology in Mochełek near Bydgoszcz. As a result of 3-year field experiment and laboratory test of grain, malt and wort, it was found that introducing sprinkler irrigation into the production process of malting barley is a step justified by the obtained quality effects. It was found that in the case of irrigated malting barley cultivations nitrogen fertilization at the rate of 30 kg∙ha-1 provides (in relation to control, non-irrigated treatment) the highest values of such parameters as weight of the technical barley crops, content of protein, extractivity of Pilsen type malt, amount of obtained wort and simplified mashing efficiency. The combination of sprinkler irrigation of malting barley plants with their nitrogen fertilization at the increased rates of 60 and 90 kg∙ha-1, resulted in the following effect - high mass of the usable grain of crops remained but their quality deteriorated. Malt produced from malting barley fertilized with nitrogen ...
The paper presents results of a controlled field experiment with sprinkler irrigation of winter oilseed rape (Latin name) cv. Arsenal F1 Linagrain and winter wheat (Latin name) cv. Franz, conducted in the vegetation season of 2016 (dry in terms of the recorded precipitation total) on a family farm in Kobylata, the Kłodawa commune, the Wielkopolskie Province. Water requirement observed as early as April was balanced by sprinkler irrigation in seasonal application rates ranging from 75 mm (rape) to 105 mm (wheat). Sprinkling of winter rape was the factor having a highly significant effect on seed yield volume, on average from 4 plots amounting to 4.1 t·ha-1 and by 17.4% greater than the yield harvested in the non-irrigated plots (control) - of 0.6 t·ha-1. Winter wheat, at the application of sprinkler irrigation, also produced greater yields (by 24%) in comparison to the non-irrigated plots. Mean grain yield of wheat in the irrigated plots was by 1.9 t·ha-1 greater. Advisability of irrigation, apart from higher yielding, may also be indicated by water use efficiency in these crops. Every mm of sprinkled water caused an increase in of rape by 7.9 kg, while in wheat by 17.8 kg. ...
