In the area of influence of the Integrated Territorial Intervention (ITI) of Castro Verde, field trials were carried out in the year of 2012/13, to study the behaviour of three species of cereal crops (wheat, triticale and oat), each with two varieties, subjected to three fertilization strategies. These strategies fertilizer units applied in each species / variety were identical, varying only the design and establishment of fertilizer according to the company supplier / manufacturer (ADP Fertilizantes, Cadubal/Yara e Deiba). In all three tested species (wheat, triticale and oats) were obtained different grain yield values. The oatmeal reached the lowest grain yield (1 686 kg ha^-1), with identical values for each of the varieties under study (‘Sta. Eulália’ and ‘Sta. Rita’). In wheat and triticale grain yield was similar with respectively 2 212 and 2 280 kg ha^-1. However, in these species, it is an advantage of the varieties under study. For wheat variety ‘Ingenio’ with 2 428 kg ha^-1 and triticale variety ‘Trimour’ with 2 617 kg ha^-1 were the varieties that achieved the highest grain yield, although with significant differences only in triticale. It was found in this way, better adaptation to soil and climatic conditions of some species / varieties, while the effect of fertilization strategy did not influence significantly grain yield.
