Response of crops to conservation tillage and nitrogen fertilization under different agroecological conditions
Effects of soil tillage (CT-conventional, SS-subsoiling, CH-chiselling, DH-disk-harrowing and NT-no-till) and nitrogen rate (reduced N1, optimal N2 and luxury N3) on yield and yield components of maize and winter wheat in two different agricultural subregions of Croatia (Magadenovac and Cacinci site), have been studied in years 2013–2014 as a part of long-term experiment. Maize yield and yield components were influenced by site properties, tillage and nitrogen treatments. The highest yields and yield components were recorded at site Magadenovac on N2 and N3. The lowest values of the yield and yield components of maize were recorded on NT and were significantly lower than CT, SS, CH and DH, among which no significant differences were recorded. Winter wheat yield and yield components were affected by site properties and nitrogen rates while soil tillage treatments had influence only on grain and straw yield and plant height. Winter wheat achieved maximum yield and yield components on a N3 and N2 and at Magadenovac site. Winter wheat grain yield was decreasing in following order: SS > DH > CH > NT > CT. The obtained results indicate the importance of optimal nitrogen fertilization and the possibility of implementation of conservation tillage for maize and winter wheat production in different agroecological conditions.
