Influence of Sowing Time on Yield and Yield Components of Spring Rapeseed in Lithuania

Sowing time, as an element, is important to improving the adaptation of cultivars environmental conditions and achieving high seed yields. The field experiment was conducted from 2018–2019 at Experimental Station Vytautas Magnus University Agriculture Academy. experimental design included treatments with different sowing dates: eight dates in 2018 10 2019. first spring rapeseed carried out when soil reached its physical maturity, i.e., it did not stick agricultural implements crumbled well. other were every seven subsequent days. From 2018–2019, emerged best early May (3 4 May), later reduced emergence rapeseed. In 2018, most pods formed on one plant sown (on 1 June), compared sowings, average 2.8 times more. 2019, by latest-sown (7 1.4 2.7 more previously crops. time have a significant effect number seeds pod. found that pod similar 2018: sowings 19 April 7 June. significantly (5 April). highest 1000-seed weight earliest-sown crop April), which 18.0% higher sowings. last-sown June) lowest. yields early-sown (20 April) highest.
