Fertigation Experiment on Saaz Hops in 2017-2019

Popis výsledku v původním jazyce

The three year (2017–2019) fertigation experiment with fine aroma hop variety Saaz was established in the Czech Republic in Saaz hop growing region. The control treatment included the contemporary growing technology without fertigation, just soil and foliar fertilization with 300 kg/ha of ammonium sulphate, 300 kg/ha of ammonium phosphate and 300 kg/ha of potassium chloride in the early spring, followed by 250 kg/ha of ammonium nitrate with limestone in May. Foliar fertilization mainly consisted of N, P, K, Zn and Mg application. The treatment with fertigation got basic dose of fertilizers (640 kg/ha of fertilizer containing NPK 20-7-10 + 4 % S, 2 % MgO) during sprouting, followed by fertigation 5-times (42,5 kg/ha of fertilizer containing NPK 12-12-36 + micro) and foliar application during vegetation period (various fertilizers containing mainly N, P, K, Zn, Mg, B, S). The amount of applied nitrogen, phosphorus and potassium was lower at the treatment with fertigation by 8,3 % N, 53,6 % P and 22,5 % K. The experiment proved the significant increase of yield by 27 %, 33 % and 16 % in 2017, 2018 and 2019 respectively at treatment with fertigation compared to control treatment and also the alpha-bitter acids content in hop cones was significantly higher in 2018 (by 14 %) at treatment with fertigation compared to control tretament. Nevertheless, in the years 2017 and 2019 there was no significant difference in alpha-bitter acids content between treatments. The results suggest that fertigation can intensify hop cultivation.
