Spring is the period when winter rapeseed plants are speeding up their development. All the activities are increasing: biomass accumulation, leaf area development, photosynthesis. To support the intensification, necessary to maximize the number of seeds and therefore the yield, the plant has to uptake big amounts of nutrients.
ZOOM ON TWO ESSENTIAL NUTRIENTS:
NITROGEN
BORON
Boron is also important at the spring period. The plant has to uptake about 300 g / ha of Boron to avoid the «flowering without seed setting» syndrome.
During this phase, the plant must grow in the best conditions: climatic stresses or assimilation problems can limit the potential of the plant to develop its photosynthetic organ and hence the yield.
