| Summary: | Cowpea is a widely grown legume, mainly in northeastern Brazil. In their cultivation, high
solubility mineral fertilizers are often employed which can cause numerous environmental impacts and
considerably increase production costs. Thus, cultivation practices that may decrease the use of mineral
fertilizers should be studied and rated. Therefore, the objective of this work was to evaluate vegetative
and productive components of cowpea submitted to different organic, inoculant and mineral fertilizers.
The treatments were distributed in randomized blocks, with nine treatments and three repetitions:
Witness (T), without fertilization; biofertilizer (B); inoculant (I); milk residue (R); biofertilizer + inoculant
(BI); dairy residue + biofertilizer (RB); milk residue + inoculant (RI); milk residue + inoculant +
biofertilizer (RIB) and the formulated NPK (M). Organic fertilizers and inoculant alone or associated do
not contribute to cowpea productivity if compared with mineral fertilizer. The use of mineral fertilization
increased cowpea productivity.
