Abstract

[Autom. eng. transl.] Biomass sorghum, due to its high productivity and low crop inputs, is considered a very interesting species for bioenergy production. However, its effect on successive crops is not widely known. To evaluate the effect of sorghum, and in particular the management of its recurrences, on the endowment of mineral nitrogen of the soil and on the production of the wheat cultivated in succession, a plot experimentation was carried out in which the effect of the burying of the sprouts is was evaluated in a factorial combination with four doses of nitrogen fertilization in wheat. From an environmental point of view, a first aspect to note is the low presence of nitrates at the end of the cultivation of biomass sorghum (14 kg N ha-1) and above all after the sprouts (9.1 kg N ha-1). Nitrogen fertilization did not significantly affect the growth of sprouts, proving to be useless and potentially harmful to the environment. The burying of the sorghum sprouts was a potentially advantageous practice, both for the yield of the wheat in succession (+ 9.3%), and for the endowment in N of the soil given that only 16.1 of the 106.8 kg N ha-1 present in the sprouts underground they are mineralized and made available to wheat.
