Effects of fall and spring primary tillage on soybean yield and 1000-grain weight in agro ecological conditions Serbia

Abstract

The effect of fall and spring primary tillage on soybean yield and 1000-grain weight was examined in a three-year study (2013-2015). The trial included cultivars with different maturity periods, developed at the Institute of Field and Vegetable Crops Novi Sad: Valjevka and Galina 0 maturity group, Sava and NS Maximus I maturity group, Rubin and Venera II maturity group. Trial subplots were prepared using different periods of primary tillage, which was conducted in fall (01–05 November) and spring (25–31 March) in Bačka Topola. The highest yields and 1000-grain weight were obtained after fall primary tillage in all the three study years.
