“…The growth of WOR plants can be strongly modified with the use of chemical growth regulators. These compounds can be applied in fall to inhibit the growth of rosettes (decrease terminal bud height, increase root collar diameter, and stimulate the development of the root system), which increases their winter hardiness, especially in early-sown WOR and during a prolonged fall growing season [36][37][38][39]. When applied in spring, growth regulators suppress the growth of the main stem and stimulate the formation of side shoots, thus minimizing the susceptibility to lodging and promoting greater sunlight interception by siliques on side shoots [22,38,40,41].…”

The aim of this study was to analyze agronomic management in the production of winter oilseed rape (WOR) in different tillage systems. The field experiment (Poland, 2016–2019) had a 35–1 fractional factorial design with two replications, where five fixed factors were tested at three levels. The experimental factors were as follows. 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) in fall, (C2)—in fall and spring; D—rate of spring nitrogen (N) fertilizer: (D0) 160, (D1) 200, (D2) 240 kg ha−1; E—rate of spring sulfur (S) fertilizer: (E0) 0, (E1) 40, (E2) 80 kg ha−1. Seed yields were the highest in the strip-till system (5.95 Mg ha−1). The effectiveness of weed control methods varied across different tillage systems. Foliar herbicides exerted the highest yield-forming effect in the strip-till system, pre-emergent and sequential herbicides were most effective in the low-till system, and pre-emergent herbicides were most effective in the conventional tillage system. Seed yields increased up to the N rate of 200 kg ha−1. The highest N rate of 240 kg ha−1 was justified only when S was applied in spring. Sulfur significantly increased seed yields (by 17%). The results of the study indicate that low-till and strip-till systems can be viable alternatives to the conventional tillage system in WOR production.

Branch during the growing seasons of 2011/2012-2012/2013. Three different varieties of winter oilseed rape were sown at their optimal sowing time after a cereal forecrop. To protect the crop against Sclerotina sclerotiorum and pod diseases three fungicides, approved for use in Poland, based on active substances that belong to different chemical groups were applied at three different timings: at the beginning of flowering (BBCH 60-61), full flowering (BBCH 64-65) and end of flowering (BBCH 67-69). The results indicate that both weather conditions and the timing of fungicide treatment significantly affect oilseed rape yield quality and quantity. Under the conditions of early infection, the application of fungicides at the beginning of the flowering stage decreases the level of infection in harvested seeds, caused mostly by Alternaria genera of fungi, which significantly worsen the quality of sowing material. Fungicides applied in the crop under stress or in poor condition had a negative impact on the content of oilseed in rape seeds. This reaction was observed to be the stronger: the weaker was the condition of oilseed rape plants.
