Evaluation of efficiency of sprinkling irri-gation in the brewing barley cultivation technology – preliminary results

A field experiment was conducted during the growing season 2010 on sandy soil in Mochełek near Bydgoszcz. The effects of irrigation and the four variants of nitrogen fertilization on yield and quality of grain from brewing barley varieties 'Mauritia' and 'Martha' were inwestigated. Growing season of barley in terms of total rainfall belonged to the wet, however, was marked by an extremely uneven distribution of rainfall in different decades. During the period of tillering and ripening stage of barley rainfall amounted to only 16.3 mm, which resulted in the need for irrigation of plants. A total of five doses of 105 mm of water was used. It was found that yields of barley grain ranged from 3.05 kg.ha-1 to 6.34 kg.ha-1, depending on the variety, irrigation and nitrogen fertilization variant. Regardless of the factors used, higher average yields of 31% was characterized by a variety of 'Martha'. The average increase in grain yield due to application of irrigation was 37.3%. This indicates the high desirability of introducing this treatment to the malting barley production technologies as a factor which increases the amount of grain yield in growing seasons characterized by the occurrence of atmospheric and agricultural dry spells in ...

Impact of sprinkling irrigation and nitrogen fertilization on yield and its quality in two malting barley cultivars

The aim of the research was an evaluation the impact of sprinkling irrigation, nitrogen fertilization as well as an interaction of the two factors on yield and malting quality of grain of two malting barley varieties‘Mauritia' and ‘Marthe'. A field experiment was conducted during the growing seasons in years 2010-2011 on sandy soil with dense subsoil in the Research Centre of University of Technology and Life Science - Mochełek nearby Bydgoszcz. This is an area in Poland of the highest average precipitation shortages and the needs of use the supplemental irrigation in terms of the climate criterion. On such type of soil, the irrigation had an interventionist role which is typical for the climatic conditions in Poland. It complemented periodic shortages of precipitation during the increased water needs of barley. Research hypothesis assumed that the use of irrigation in the technology of barley cultivation will increase and stabilize yields of grain and contribute to the acquisition of raw material that meets the criteria of brewing, regardless of the agricultural droughts occurring in a growing season. It was also assumed that, in terms of irrigation it would be possible to use higher doses of fertilizer than in conventional ...
