Influence of rain during harvest on quality traits of wheat

Abstract

In the past 50 years, climatic changes affects cropping systems across Europe. Generally, Pannonian basin is one of the most vulnerable area of Europe influenced by climate changes characterized by a relatively short growing season, winter frosts, occasional spring heats and frequent drought stresses at the end of grain filling period. Besides the temperature increase and precipitation decrease, high year-to-year weather variability represent additional threat to the high winter wheat production. Appearance of prolonged heavy-rainfall periods, especially during harvest, causing harvest delay, leading to significant grain yield losses. Moreover, heavy rain decrease wheat quality traits effects additional economic impact. Therefore the aim of this study was to estimate influence of high amount of precipitation during harvest on wheat quality traits. The field trial was arranged in split-split plot system with nitrogen fertilization and harvest date as main factors and variety as sub-plot factor. The trial was performed in three replications, with size of experimental plot of 5 m2 (5m x 1m). Trial treatments included fertilization with four growing nitrogen in-use doses: 0, 50, 100 and 150 kg N ha-1, six wheat cultivars and two date of harvest: 25th June 2018 and 13th July 2018 (106 mm of rain from 25th June). Six novel wheat cultivars: NS Todorka, NS Javorka, NS Petrija, NS Obala, NS Epoha and NS Mila were used as material.
