Résumé:
Considering the advance of soil degradation that severely compromises the quality of
life and food security, sobreturo in the areas of family agro-ecosystems of semiarid
region, it is essential that research enable viable alternatives for farmers, for the
establishment of economic, ecological and social balance of region. In this sense it is
important to identify forage species with a short cycle that can contribute to animal feed
and the promotion of soil fertility, identifying the best means of production. It is important
to know the best spacing for biomass production of short-cycle fodder, to promote a
productivity that is interesting for local producers. This study aimed to evaluate the
fitometria of pearl millet and sorghum produced under organic fertilization and in two
spaces, when grown in Cariri of Paraiba. The experiment was conducted in a Luvisol. It
was used the experimental randomized block design, with four replications. The
treatments were two spacings, and two fodder. The survey results indicate that the
reduction in spacing influenced the growth in height of the two cultures, and although
the sorghum has shown higher values, millet was evident as good fodder for the
production of green biomass. Depending on the results and considering the demand for
forage species of short cycle, linked the need for conservation of the family agro soils, it
is possible to recommend the use of millet without losses to the farmer, due to its
potential, its tolerance conditions edaphoclimatic local and culture has potential use in
any of the phenological stages, by the absence of hydrogen cyanide (HCN) and tannins
that are toxic to cattle, and that millet exceeds sorghum in crude protein, being great
alternative for the production of straw.
