Utjecaj različitih sustava konzervacijske obrade tla i gnojidbe dušikom na infekciju zrna pšenice vrstama Fusarium

Abstract

The effect of different conservation soil tillage (CST) treatments and different level of nitrogen fertilization on Fusarium wheat grain infection on two locations are presented in this paper. The research was conducted on winter wheat with different soil tillage treatments: conventional tillage to 30 cm depth, subsoiling to 35-40 cm depth, chiselling up to 25 cm, disk-harrowing to 10-15 cm and no-tillage, without any tillage treatments and three different nitrogen rates (N1 - amount reduced by 30% of recommended; N2 - according to standard recommendation and N3 - amount increased by 30% of recommended). The occurrence of Fusarium species was determined in all the tested variants of tillage and fertilization treatments. The effect of reduced fertilization (N1) on Fusarium sp. grain infection in all tillage treatments was statistically lower in comparison with other (N2 and N3) nitrogen treatments. The lowest percentage of wheat grains infected with Fusarium sp. was recorded in conventional tillage on location Magadenovac and no tillage treatments on location Cacinci.

Oxidative Status and Antioxidative Response to Fusarium Attack and Different Nitrogen Levels in Winter Wheat Varieties

“…Considering different experimental conditions, various reports on the effect of nitrogen fertilization on FHB are available in the literature. According to some studies, high nitrogen levels increase disease incidence and intensity [16][17][18], whereas others reported restriction impact of nitrogen on Fusarium infection [19][20][21]. In the present study, in, Ficko, Galloper, and Felix varieties high nitrogen levels caused an increase in visual symptoms, compared to low nitrogen levels.…”

“…Step 3. Calculation of objective weights ( ) The last step is the linear normalization of dr to find the relative weight of each criterion is calculated using Equation (18). The results are presented in Table 15.…”

Tillage and straw management impact on soil structure, compaction and soybean yield on fluvisol

“…Previous research reveals that straw residue can have positive and negative implications for crop production. Most common negatives are associated with stronger disease and pest development (Vrandečić et al, 2014;Krupinsky et al, 2002), demanding tillage and sowing (Bogunović et al, 2018a;Đekemati et al, 2019), the onset of nitrogen depression, and the need for more knowledge and acquisition of specialized machinery (Jug et al, 2008).…”

The effect of tillage systems and dosages of cow manure on weed and soybeans yield (Glycine max, Merrill)

“…Soil tillage systems and application of fertilizers, whether inorganic or organic can increase the production of soybeans. Soil tillage is the essential components of soil management (Vrandecic et al, 2014). Tillage can improve environmental conditions and make them suitable for plant growth (Royyani et al 2018).…”
