Opis:
In the past few years, Poland has been growing into a leader in the cultivation of highbush blueberry in Europe and now occupies a very high 3rd place in world production, just behind the USA and Canada. The leading position on the European market, the growing demand for the fruit and the possibility of entering new markets present to Polish producers new opportunities and increase the number of new plantings. In the cultivation of blueberry, irrigation is a factor determining the size and quality of the crop, as the blueberry plant, due to its shallow root system, requires adequate moisture and permeability in the topsoil, generally throughout the entire growing period. The results obtained in several studies confirm the high effectiveness of blueberry irrigation, particularly on plantations at their full fruiting potential. The rise in yield achieved through the use of irrigation averaged 95%, corresponding to 4.51 t·ha-1. The average irrigation efficiency coefficient was a 41.37 kg rise in fruit yield per 1 mm (10 m3) of water used for irrigation.

Opis:
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.

Opis:
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.

Opis:
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 at the rates of 60 and 90 kg·ha-1, in spite of applied sprinkler irrigation, was characterized by unacceptable – from the technological point of view - increased content of protein in malt in the amount of over 11.5% d.m., as well as huge decrease in malt extractivity (even by 2%) and lower, simplified mashing efficiency (below 70%).

Opis:
The work presents the research results of impact and effects of applying irrigation by sprinkling machine on the yield of medium-early potatoes. The research and observation conducted in growing seasons 2011, 2012 and 2013, on the private agricultural and production farm, in Kurów, located in the Ostrów Wielkopolski district, in the borough of Nowe Skalmierzyce, in the Wielkopolska Province. The area of the farm was 31 ha and 4 ha of potatoes were irrigated. The study confirmed that by using interventional irrigation in periods of water deficits, the medium-early potato yield increased by 30%, against the non-irrigated area. The evaluation of the research results also showed that patchy distribution of precipitation, in the analyzed growing season had an adverse influence on the crop. Frequent and long dry periods contributed to losses and decrease in potato yield.
