Abstract/Contents: | "Nitrogen concentration in leaves at the beginning of growth responds to nitrogen rates applied in autumn, which gives a possibility of using this indicator for predicting needs for spring fertilization. Diversification of the chlorophyll index at the beginning of shooting according to fertilization level in early spring can be useful for determination of the supplementary rate. In respect of seed yield, in the first production year applying of 20 kg N ha-1 in autumn and 40 kg ha-1 in spring during starting of growth is sufficient. For maintaining a similar productivity in the second year, at the autumn application of 20 or 40 kg N ha-1 it is necessary to apply not less than 60 kg ha-1 in early spring." |
