Effect
Increased produce quality
Kelpak SL treated Winter Rapeseed, cv.Chagall, grown in different fertilization regimes had at flowering on average a 13.6 % higher dry matter accumulation and a 13.3 % higher Mg accumulation, at development of fruits a 8.1 % higher dry matter accumulation and a 10.5 % higher Mg accumulation and at fruit ripening a 12.2 % higher dry matter accumulation and a 12.9 % higher Mg accumulation compared to the untreated control. Kelpak had most effect on Rapeseed cultivated with the high dose of NPK + S fertilization.
