Fertilisation systems and rape biomass production.

Starting from the presence on the market of some various assortments of fertilizers, from the critical situation in the field of fertilisers with a view to supporting agricultural production in many agricultural exploitations, as well as from the need to implement some sustainable agricultural systems, we tested a few fertiliser assortments (Bionat Plus, Bionex, and Terrasorb) at different rates and fertilisation times. Testing was done in winter rape as a result of the increasing share of the rape and of the increasing interest in rape. Production results we obtained, such as presented in Table 2 and in Figure 2, point out the favourable fertilising contribution of the three tested fertilisers, materialised in significant increases in yield; to note the fertiliser Terrasorb, with the most constant yields in all the variants applied and with the highest yield in the experiment.
