key words: sprinkler irrigation, faba bean, increase of yield, nitrogen fertilization, the yield of protein


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 experiments, it was not found an influence of nitrogen fertilizer on the amount of yield of seed, the best results were obtained in conditions without nitrogen or with the dose of 30 kg.ha-1. The yield of seed, the subsequent years of research and factors used in the experiment affected the yield of protein. In 2010 from the control plots were collected only 0,39 t.ha-1 of protein, and in 2012 from the irrigated plots were received more than 2 tons.
