Resumo(s)
Through this work it was meant to analyse grain legumes evolution, confirming their
role in agriculture. Its study is associated to fundamental issues related with sustainable
agriculture concerns, combined with environmental issues and also the role of this sector on
Portuguese economy.
Grain legumes have always been associated to human consumption and animal
nutrition, besides its particularity of N2 -fixation, being considered good cultural precedents.
The main goal was to stimulate both economic and environmental benefits of beans
and grain legumes productions and area expansion.
For this analysis, and in order to achieve the main goal some research data, which
could explain both bean (Phaseolus vulgaris L.) and chickpea (Cicer arietinum L.) sectors
evolution in portugues market, were collected; in addition, experimental tests in where these
same legumes were included were selected.
So the objective was fulfilled and, on a national scope, was predicted how much can
be saved on fertilizer, which can be expressed by 22 euros per hectare, and, on an
environmental scope, about 9,6 kg of leached Nitrogen/ ha can be reduced. In the same way
the net return of both products can be expressed by 88 million euros through the increase of
production
