Winter Oilseed Rape: Agronomic Management in Different Tillage Systems and Seed Quality

A three-year study was conducted to analyze agronomic management in the production of winter oilseed rape (WOSR) under different tillage systems. field experiment at University’s Agricultural Experiment Station Bałcyny (north-eastern Poland), three growing seasons (2016/2017, 2017/2018, and 2018/2019). The had a 35–2 resolution III fractional factorial design with five fixed factors that were tested levels intensity. experimental were: A—tillage: (A0) strip-till, (A1) low-till, (A2) conventional tillage; B—weed control: (B0) pre-emergent, (B1) foliar, (B2) sequential; C—growth regulation: (C0) none, (C1) fall, (C2)—in fall spring; D—rate nitrogen (N) fertilizer applied spring: (D0) 160, (D1) 200, (D2) 240 kg ha−1; E—rate sulfur (S) (E0) 0, (E1) 40, (E2) 80 ha−1. crude fat (CF) content WOSR seeds highest strip-till system (498 g kg−1 dry matter, DM), total protein (TP) (196 DM) low-till neutral detergent fiber (NDF) higher harvested from systems than system. plants grown accumulated more (by 0.4%) polyunsaturated fatty acids (PUFAs) less 0.5–0.6%) monounsaturated (MUFAs). An increase N rate 160–200 ha−1 decreased CF (495 vs. 484 increased TP (191 199 DM). Sulfur fertilization induced 34% glucosinolate (GLS) concentrations seeds, mainly by enhancing biosynthesis alkenyl GLS 39%).
