The paper presents the results of strict field experiments with irrigation on sandy soil of faba bean (Vicia faba L. minor) varieties "Bobas" conducted in 2005-2009 at the Research Station of the Faculty of Agriculture and Biotechnology, University of Technology and Life Sciences in Mochełek near Bydgoszcz. Subsequent growing seasons were very differential, especially rainfall, which determined the amount of applied irrigation doses. In 2009 there was no need for irrigation, and in 2008 an additional 200 mm of water was distributed. Faba bean seed yield for the control plots ranged in successive years from 0.58 t.ha-1 (2008) to 5.26 t.ha-1 (2009r.). The sprinkler irrigation influenced the significant increase of yield up to 3.12 t.ha-1, it was highly correlated with total precipitation in May-July period and the dose of irrigated water. The lower rainfall and the higher doses of irrigation, the greater were the effects of irrigation production. In the experiment, it was found a high efficiency of irrigation, which ranged from 14.8 to 34.8 kg of an additional yield received from each 1 mm of wa-ter, depending on the year.

The paper presents the results of a field experiments with irrigation faba bean cultivar 'Olga' which were carried out on sandy soil in the years 2010-2012 nearby Bydgoszcz in the Research Centre of University of Technology and Life Science - Mochełek. Particular vegetation seasons were different, especially related to rainfall, which determined the amount of applied irrigation doses. The highest-level need for irrigation occurred in 2010, when 180 mm of irrigated water was used; while in subsequent years rainfalls were distributed more preferably thus for irrigation were used 65 mm. Based on the results, it was found that the water needs of faba bean cultivated on sandy soil in the period from April to August amounted to about 400 mm. Seed yield of faba bean collected from control plots ranged in successive years from 1.23 t.ha-1 (2010) to 5.55 t.ha-1 (2012). Irrigation increased the yield significantly by an average of 1.59 t.ha-1, the highest increase in crop (3.66 t.ha-1) was obtained in 2010 by using the highest dose of irrigation. Yield collected from irrigated plots were not stable in the subsequent years, they averaged 5.00 t.ha-1, varying between 3.84 t.ha-1 (2011), and 6.27 t.ha-1 (2012). Based on the results of ...
The field experiment was carried out in 2004-2006 in Chlebówko localized 20 km from Stargard Szczeciński and 5 km north-east from Stara Dąbrowa commune - 53°27'N and 15°10'E. The area is elevated 62-72 m above mean se level (ASL). The influence of irrigation, tillage system, and NPK mineral nutrition on weed infestation of faba bean variety ‘Titus' with determined development rate, was evaluated. The weed infestation degree in the faba bean plantation depended on moisture conditions, fertilization rates, and tillage system. Irrigation increased the number, fresh weight, and dry matter of weeds, respectively by 92%, 130%, and 138%. Likewise, increasing nutrition elevated values of these parameters by 46%, 80%, and 95%. The tillage simplifications enhanced the weed population, particularly on irrigated and fertilized objects. Irrigation, mineral nutrition, and simplified tillage caused compensation of spring, winter and perennial weed species on plantation of faba bean ‘Titus'. Chenopodium album, Stellaria media, and Polygonum convolvulus predominated on studied plots. ...
The paper presents the production effects of irrigation of sugar beet, winter rape, spring barley, soybean and faba bean, obtained in long-term (2005-2020) field experiments. The experiments were carried out on light soil with compact subsoil in the Bydgoszcz area. Significant, rectilinear relationships were found between increases in plant yields under the influence of sprinkler irrigation and precipitation totals in the vegetation periods of these plants, especially in the phases of increased water demand. The average long-term production effects of irrigation of the surveyed crops, which are presented in the work and their variability over the long-term period, may be the basis for assessing the desirability of irrigation of plants in areas of comparable soil and precipitation conditions. ...
